Godep scripts cleanup

Another try at sanitizing godep scripts.  Instead of messing with containers, or assuming anything about GOPATHs, let's just work with whatever GOPATH we are given.  If you want sane godep/restore behavior you can use `./hack/run-in-gopath.sh ./hack/godep-restore.sh`.  This will restore into your _output dir.  You can update deps yourself, and then run `./hack/run-in-gopath.sh ./hack/godep-save.sh`.

xref  #44873

This also checks out godep into your working GOPATH.  Without this, we have to `go get` it every time.  We should just vendor it.

#v71 (2016/05/24)
* Preserve permissions on copied files.
#v70 (2016/05/20)
* Fix the May changelog dates

#v69 (2016/05/16)
* Make sure `devel-<short sha>` enabled `vendor/` unless there is a classic Godep _workspace already.
#v68 (2016/05/16)
* `devel-<short sha>` is always considered newer than any released go version
#v67 (2016/05/13)
* Attempt to handle missing deps a little better.
#v66 (2016/05/10)
* Use `git remote show origin` to find the default branch when restoring a git based package repository that is in detached head state
#v65 (2016/05/09)
* Rewrite update so that it considers new transitive dependencies, both in the same repo and outside of it.
#v64 (2016/05/09)
* godep update golang.org/x/tools/go/vcs
#v63 (2016/05/03)
* Support recording devel-<short sha> so development versions of Go can be matched
#v62 (2016/04/07)
* Note new go1.6+ behavior of not checking out master in README / restore help text.

#v60 (2016/03/18)
* Make the $GOPATH check a warning.
#v59 (2016/03/18)
* Enforce requirement to be inside of a go src directory. A lot of time is usually spent
tracking down bug reports where people are doign stuff from outside of their $GOPATH. This
should help with that, at least until there it time to properly test godep use outside of a
$GOPATH and fix the issues.
#v58 (2016/03/15)
* Add GodepVersion to Godeps.json file so that as godep changes / adds features / fixes bugs we can know which version of godep most recently wrote out the file.
#v57 (2016/03/07)

# v55 2016/02/22
* re-saved deps to clean out extra stuff (see v54; godep restore; godep save -r=false; rm -rf Godeps; godep save -r). We're still using a workspace with rewrites so users of older go version can still go get this tool.
* Replace simple == with strings.EqualFold in listFiles to avoid problems with case insensitive filesystems ("Code" != "code" when doing a byte by byte comparison)
# v54 2016/02/22
* Update some docs around vendor/
* More precise recording of dependencies. Removed recursive copying of sub directories of a package (precise vendoring). This should allow using `./...` with the go tool for compilation of project using `vendor/`. See https://github.com/tools/godep/pull/415

* Better error messages when parsing Godeps.json: Fixes #372
# v42 2015/12/22
* Fix a bunch of GO15VENDOREXPERIMENT issues
* Find package directories better. Previously we used build.FindOnly which didn't work the way I expected it to (any dir would work w/o error).
* Set the VendorExperiment bool based on go version as 1.6 defaults to on.
* A bunch of extra debugging for use while sanity checking myself.
* vendor flag for test structs.
* Some tests for vendor/ stuff:
* Basic Test
* Transitive
* Transitive, across GOPATHs + collapse vendor/ directories.
* Should Fix #358
# v41 2015/12/17

an external package for vendoring when you ran `goodep save -r ./... github.com/some/other/package`
# v40 2015/12/17

* Fixes #186
* Don't bother restoring/downloading if already done.
# v37 2015/12/15
* Change up how download/restore works a little
* Try to load the package after downloading/restoring. Previously
that was done too early in the process.

* Remove the deprecated copy option.
# v3 2015/08/26
* Ignore testdata directories
# v2 2015/08/11
* Include command line packages in the set to copy
This is a simplification to how we define the behavior
of the save command. Now it has two distinct package
parameters, the "root set" and the "destination", and
they have clearer roles. The packages listed on the
command line form the root set; they and all their
dependencies will be copied into the Godeps directory.
Additionally, the destination (always ".") will form the
initial list of "seen" import paths to exclude from
copying.
In the common case, the root set is equal to the
destination, so the effective behavior doesn't change.
This is primarily just a simpler definition. However, if
the user specifies a package on the command line that
lives outside of . then that package will be copied.
As a side effect, there's a simplification to the way we
add packages to the initial "seen" set. Formerly, to
avoid copying dependencies unnecessarily, we would try
to find the root of the VCS repo for each package in the
root set, and mark the import path of the entire repo as
seen. This meant for a repo at path C, if destination
C/S imports C/T, we would not copy C/T into C/S/Godeps.
Now we don't treat the repo root specially, and as
mentioned above, the destination alone is considered
seen.
This also means we don't require listed packages to be
in VCS unless they're outside of the destination.
# v1 2015/07/20
* godep version command
Output the version as well as some godep runtime information that is
useful for debugging user's issues.
The version const would be bumped each time a PR is merged into master
to ensure that we'll be able to tell which version someone got when they
did a `go get github.com/tools/godep`.

## Why do I need to check in `vendor/`?
godep's primary concern is to allow you to repeatably build your project. Your
dependencies are part of that project. Without them it won't build. Not
committing `vendor/` adds additional external dependencies that are outside of
your control. In Go, fetching packages is tied to multiple external systems
(DNS, web servers, etc). Over time other developers or code hosting sites may
discontinue service, delete code, force push, or take any number of other
actions that may make a package unreachable. Therefore it's the opinion of the
godep authors that `vendor/` should always be checked in.
## Should I use `godep restore`?
Probably not, unless you **need** to. Situations where you would **need** to are:
1. Using older Godep Workspaces (`Godeps/_workspace`) and not using `godep go
<cmd>`.
1. Resetting the state of $GOPATH to what is in your `Godeps.json` file in order
to cleanly re-vendor everything w/o upgrading/changing any deps. This is
useful when [migrating](https://github.com/tools/godep#migrating-to-vendor)
from workspaces to `vendor` or when a bug is fixed in `godep` that cleans up
a previous vendoring error.

## Godep
[![Build Status](https://travis-ci.org/tools/godep.svg)](https://travis-ci.org/tools/godep)
[![GoDoc](https://godoc.org/github.com/tools/godep?status.svg)](https://godoc.org/github.com/tools/godep)
godep helps build packages reproducibly by fixing their dependencies.
This tool assumes you are working in a standard Go workspace, as described in
http://golang.org/doc/code.html. We expect godep to build on Go 1.4* or newer,
but you can use it on any project that works with Go 1 or newer.
Please check the [FAQ](FAQ.md) if you have a question.
## Install
```console
$ go get github.com/tools/godep
```
## How to use godep with a new project
Assuming you've got everything working already, so you can build your project
with `go install` and test it with `go test`, it's one command to start using:
```console
$ godep save
```
This will save a list of dependencies to the file `Godeps/Godeps.json` and copy
their source code into `vendor/` (or `Godeps/_workspace/` when using older
versions of Go). Godep does **not copy**:
- files from source repositories that are not tracked in version control.
- `*_test.go` files.
- `testdata` directories.
- files outside of the go packages.
Godep does not process the imports of `.go` files with either the `ignore`
or `appengine` build tags.
Test files and testdata directories can be saved by adding `-t`.
Read over the contents of `vendor/` and make sure it looks reasonable. Then
commit the `Godeps/` and `vendor/` directories to version control.
## The deprecated `-r` flag
For older versions of Go, the `-r` flag tells save to automatically rewrite
package import paths. This allows your code to refer directly to the copied
dependencies in `Godeps/_workspace`. So, a package C that depends on package
D will actually import `C/Godeps/_workspace/src/D`. This makes C's repo
self-contained and causes `go get` to build C with the right version of all
dependencies.
If you don't use `-r`, when using older version of Go, then in order to use the
fixed dependencies and get reproducible builds, you must make sure that **every
time** you run a Go-related command, you wrap it in one of these two ways:
- If the command you are running is just `go`, run it as `godep go ...`, e.g.
`godep go install -v ./...`
- When using a different command, set your `$GOPATH` using `godep path` as
described below.
`-r` isn't necessary with go1.6+ and isn't allowed.
## Additional Operations
### Restore
The `godep restore` installs the
package versions specified in `Godeps/Godeps.json` to your `$GOPATH`. This
modifies the state of packages in your `$GOPATH`. NOTE: `godep restore` leaves
git repositories in a detached state. `go1.6`+ no longer checks out the master
branch when doing a `go get`, see [here](https://github.com/golang/go/commit/42206598671a44111c8f726ad33dc7b265bdf669).
Please see the [FAQ](https://github.com/tools/godep/blob/master/FAQ.md#should-i-use-godep-restore) section about restore.
### Edit-test Cycle
1. Edit code
1. Run `godep go test`
1. (repeat)
### Add a Dependency
To add a new package foo/bar, do this:
1. Run `go get foo/bar`
1. Edit your code to import foo/bar.
1. Run `godep save` (or `godep save ./...`).
### Update a Dependency
To update a package from your `$GOPATH`, do this:
1. Run `go get -u foo/bar`
1. Run `godep update foo/bar`. (You can use the `...` wildcard, for example
`godep update foo/...`).
Before comitting the change, you'll probably want to inspect the changes to
Godeps, for example with `git diff`, and make sure it looks reasonable.
## Multiple Packages
If your repository has more than one package, you're probably accustomed to
running commands like `go test ./...`, `go install ./...`, and `go fmt ./...`.
Similarly, you should run `godep save ./...` to capture the dependencies of all
packages in your application.
## File Format
Godeps is a json file with the following structure:
```go
type Godeps struct {
ImportPath string
GoVersion string // Abridged output of 'go version'.
GodepVersion string // Abridged output of 'godep version'
Packages []string // Arguments to godep save, if any.
Deps []struct {
ImportPath string
Comment string // Description of commit, if present.
Rev string // VCS-specific commit ID.
}
}
```
Example Godeps:
```json
{
"ImportPath": "github.com/kr/hk",
"GoVersion": "go1.6",
"Deps": [
{
"ImportPath": "code.google.com/p/go-netrc/netrc",
"Rev": "28676070ab99"
},
{
"ImportPath": "github.com/kr/binarydist",
"Rev": "3380ade90f8b0dfa3e363fd7d7e941fa857d0d13"
}
]
}
```
## Migrating to vendor/
Godep supports the Go 1.5+ vendor/
[experiment](https://github.com/golang/go/commit/183cc0cd41f06f83cb7a2490a499e3f9101befff)
utilizing the same environment variable that the go tooling itself supports
(`GO15VENDOREXPERIMENT`).
godep mostly works the same way as the `go` command line tool. If you have go
1.5.X and set `GO15VENDOREXPERIMENT=1` or have go1.6.X (or devel) `vendor/`
is enabled. **Unless** you already have a `Godeps/_workspace`. This is a safety
feature and godep warns you about this.
When `vendor/` is enabled godep will write the vendored code into the top level
`./vendor/` directory. A `./Godeps/Godeps.json` file is created to track
the dependencies and revisions. `vendor/` is not compatible with rewrites.
There is currently no automated migration between the old Godeps workspace and
the vendor directory, but the following steps should work:
```term
# just to be safe
$ unset GO15VENDOREXPERIMENT
# restore currently vendored deps to the $GOPATH
$ godep restore
# The next line is only needed to automatically undo rewritten imports that were
# created with godep save -r.
$ godep save -r=false <pkg spec>
# Remove the old Godeps folder
$ rm -rf Godeps
# If on go1.5.X to enable `vendor/`
$ export GO15VENDOREXPERIMENT=1
# re-analyze deps and save to `vendor/`.
$ godep save <pkg spec>
# Add the changes to your VCS
$ git add -A . ; git commit -am "Godep workspace -> vendor/"
# You should see your Godeps/_workspace/src files "moved" to vendor/.
```
## Releasing
1. Increment the version in `version.go`.
1. Tag the commit with the same version number.
1. Update `Changelog.md`.

Short: "list and copy dependencies into Godeps",
Long: `
Save writes a list of the named packages and their dependencies along
with the exact source control revision of each package, and copies
their source code into a subdirectory. Packages inside "." are excluded
from the list to be copied.
The list is written to Godeps/Godeps.json, and source code for all
dependencies is copied into either Godeps/_workspace or, if the vendor
experiment is turned on, vendor/.
The dependency list is a JSON document with the following structure:
type Godeps struct {
ImportPath string
GoVersion string // Abridged output of 'go version'.
Packages []string // Arguments to godep save, if any.
Deps []struct {
ImportPath string
Comment string // Tag or description of commit.
Rev string // VCS-specific commit ID.
}
}
Any packages already present in the list will be left unchanged.
To update a dependency to a newer revision, use 'godep update'.
If -r is given, import statements will be rewritten to refer directly
to the copied source code. This is not compatible with the vendor
experiment. Note that this will not rewrite the statements in the
files outside the project.
If -t is given, test files (*_test.go files + testdata directories) are
also saved.
For more about specifying packages, see 'go help packages'.

mismatched versions while migrating
It looks like you are switching from the old Godeps format
(from flag -copy=false). The old format is just a file; it
doesn't contain source code. For this migration, godep needs
the appropriate version of each dependency to be installed in
GOPATH, so that the source code is available to copy.
To fix this, run 'godep restore'.
