a96a26c62f Handle compressed tars in ApplyLayer
When pulling from a registry we get a compressed tar archive, so
we need to wrap the stream in the right kind of compress reader.

Unfortunately go doesn't have an Xz decompression method, but I
don't think any docker layers use that atm anyway.

78c22c24b3 ApplyLayer: Fix TestLookupImage
The TestLookupImage test seems to use a layer that contains
/etc/postgres/postgres.conf, but not e.g. /etc/postgres.

To handle this we ensure that the parent directory always
exists, and if not we create it.

818c249bae archive: Implement ApplyLayer directly
Rather than calling out to tar we use the golang tar parser
to directly extract the tar files. This has two major advantages:

1) We're able to replace an existing directory with a file in the
   new layer. This currently breaks with the external tar, since
   it refuses to recursively remove the destination directory in
   this case, and there are no options to make it do that.

2) We avoid extracting the whiteout files just to later remove them.

006e2a600c ApplyLayer() use RemoveAll to handle removing directories
rmTargetPath can be a directory, so we have to use RemoveAll() or we
will fail to whiteout non-empty directories.

6f3c32eb18 archive.ApplyLayer() - handle directory whiteouts
When directories are white-outed we can get called with the previously
removed directories. Handle this with os.IsNotExist(error).

484804abff archive.ApplyLayer() remove files recursively
Some aufs metadata are directories, and whiteouts can be for
directories, so use os.RemoveAll() for these.
