Leave in btrfs by default, but add go build tags to exclude it.
`go build -tags containerd_no_btrfs` will leave that driver out.
As the current containerd/btrfs code needs link to libbtrfs*.so, but not
all distros provide it.

This mainly fixes Linux vs generic Unix differences, with some
differences between Darwin and Freebsd (which are close bit not
identical). Should make fixing for other Unix platforms easier.
Note there are not yet `runc` equivalents for these platforms;
my current use case is image manipulation for the `moby` tool.
However there is interest in OCI runtime ports for both platforms.
Current status is that MacOS can build and run `ctr`, `dist`
and `containerd` and some operations are supported. FreeBSD 11
still needs some more fixes to continuity for extended attributes.

This allows one to edit content in the content store with their favorite
editor. It is as simple as this:
```console
$ dist content edit sha256:58e1a1bb75db1b5a24a462dd5e2915277ea06438c3f105138f97eb53149673c4
```
The above will pop up your $EDITOR, where you can make changes to the content.
When you are done, save and the new version will be added to the content store.
The digest of the new content will be printed to stdout:
```console
sha256:247f30ac320db65f3314b63b908a3aeaac5813eade6cabc9198b5883b22807bc
```
We can then retrieve the content quite easily:
```console
$ dist content get sha256:247f30ac320db65f3314b63b908a3aeaac5813eade6cabc9198b5883b22807bc
{
"schemaVersion": 2,
"mediaType": "application/vnd.docker.distribution.manifest.v2+json",
"config": {
"mediaType": "application/vnd.docker.container.image.v1+json",
"size": 1278,
"digest": "sha256:4a415e3663882fbc554ee830889c68a33b3585503892cc718a4698e91ef2a526"
},
"annotations": {},
"layers": [

"mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip",
"size": 1905270,
"digest": "sha256:627beaf3eaaff1c0bc3311d60fb933c17ad04fe377e1043d9593646d8ae3bfe1"
}
]
}
```
In this case, an annotations field was added to the original manifest.
While this implementation is very simple, we can add all sorts of validation
and tooling to allow one to edit images inline. Coupled with declaring the
mediatype, we could return specific errors that can allow a user to craft
valid, working modifications to images for testing and profit.

To allow the querying of usage for snapshots, we define a new method on
the snapshotter to query the resources in use by a single snapshot.
Conversely, it can be said that if the snapshot was deleted, the
reported amount of usage would be recovered.
There are few problems with this model in the implementation of btrfs
that need to be worked out. In btrfs, it is hard to resolve the amount
of data usage with the use of quotas but these may report valuables that
are incompatible with the model.
