If this is set, and it normally shouldn't be, the config file will not
add the in tree Godeps to the GOPATH. So all of them must be solved by
the KUBE_EXTRA_GOPATH
This fixes `hack/test-go.sh pkg/apiserver -test.run=<a_specific_test_name>`
which was broken by PR #1116.

add usage
verify flag value for -i is numeric
allow multiple targets on the command line
actually capture coverage output
fix lingering GOFLAGS undef issue
fix issue with -i not working at all: ((x++)) returns 1 when x is 0, which is
incompatible with "set -e"
Set the values of major and minor version based on the output of the
`git describe` command, which uses annotated tags as source of
versioning information.
Minor will get a "+" appended whenever the annotated tag does not match
the tree exactly (including when the tree is dirty.) So that only
official releases will have a "bare" minor version, all others will have
a "+" to indicate the binaries contain changes from the released version
in minor.
(This is similar to how versions of development builds of the Linux
kernel work.)
Tested:
- With no annotated tags:
$ hack/build-go.sh
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"0", Minor:"1+", GitVersion:"v0.1+", GitCommit:"7d29873bdee87efacaace30ab3602297cacf1b4f", GitTreeState:"clean"}
- Tagging current version on a clean git tree:
$ git tag -a -m 'Test tag v2.3' v2.3
$ hack/build-go.sh
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"2", Minor:"3", GitVersion:"v2.3", GitCommit:"7d29873bdee87efacaace30ab3602297cacf1b4f", GitTreeState:"clean"}
- Tagging current version on a dirty git tree:
$ git tag -a -m 'Test tag v2.3' v2.3
$ touch test.txt # this is enough to mark the tree as dirty
$ hack/build-go.sh
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"2", Minor:"3+", GitVersion:"v2.3-dirty", GitCommit:"7d29873bdee87efacaace30ab3602297cacf1b4f", GitTreeState:"dirty"}
- Tagging a previous version on a clean tree:
$ git tag -a -m 'Test tag v2.3' v2.3 HEAD~5
$ hack/build-go.sh
$ _output/go/bin/kubecfg -version=raw
version.Info{Major:"2", Minor:"3+", GitVersion:"v2.3-6-g7d29873bdee87e", GitCommit:"7d29873bdee87efacaace30ab3602297cacf1b4f", GitTreeState:"clean"}

when building on a tree with modified files in it.

Run the snippet that creates the output/go/ tree in a subshell.
Tested:
- Built it with hack/build-go.sh
- Ran release/build-release.sh successfully.
- Moved away the git tree to confirm no regression in PR #1073.
- Sourced hack/config-go.sh in the shell, confirmed no variable or
function other than the expected ones leaked into the environment.
- Used `git grep` to confirm the no longer exported variables were
not in use by any script other than config-go.sh.

The old method (using `readlink`) was convoluted and not portable. We
can achieve the same result using only bash builtins.

Add a section for environment variables in config-go.sh. Document the
three public environment variables defined by this script. Make sure the
variables get exported so that they can be used by commands spawned by a
shell that sourced the config script.

This is caused by bash thinking that an empty array is the same as an
undefined variable and `set -o nounset` treating that as an error.
Fix that by using an empty string as the default for the expansion.
Fixes PR #1069 (6e25f60288).
Tested:
- Before this patch:
$ mv .git .gitbackup
$ hack/build-go.sh
/home/filbranden/devel/kubernetes/hack/config-go.sh: line 55: ldflags[*]: unbound variable
- After this patch:
$ mv .git .gitbackup
$ rm -rf output/
$ hack/build-go.sh
$ output/go/bin/kubelet -version
