This allows for xattr keywords to include spaces and other such options
(which is perfectly valid according to the definition of Lsetxattr --
any character except '\x00' is fair game).

Because of how xattr works (it will not be set on all files, but it's
possible for it to be added to a file without changing any other key)
it's necessary that we _always_ compute a diff when we hit an inode that
has xattr keys set.

In certain circumstances (such as the manifest generation of a
filesystem as an unprivileged user) it is important to provide hooks
that override the default os.* implementation of filesystem-related
functions.
In order to avoid merging too much code from outside projects (such as
umoci) this is implemented by providing FsEval hooks to Walk() and
Check(). This allows for users of go-mtree to modify how filesystem
checks are done, without compromising the simplicity of go-mtree's code.

The current Vis() and Unvis() are using the C implementation from
MTREE(8).
But that means that cgo is used, which is not always desired.

This cleans up the Makefile target, and drops the dependency to point to
the $root path of the repo.

The BSD format needed a slight tweak to handle mtree.Extra
and mtree.Missing cases. It currently only handled the 'Modified'
cases and therefore was not showing missing or extra files during
validation.
Since not every keyword applies to every type entry, include a comment
with the keywords the manifest was generated with.

Adding another test validated from the FreeBSD workflow.
Just because the keywords requested to be validated are not present in
the manifest, it is not an error.
Also, if the keywords from a new manifest are not present in a prior
manifest, then only compare the common keywords.

symlink(2) is a very dumb syscall, and allows you to put any damn value
you please inside a symlink. In addition, spaces are valid path
characters which causes issues with keyword parsing. So use Vis() and
Unvis() to safely store an encoded version of the path.
This also adds a cli test for this behaviour.
