Make "bup meta -tvv" output identical to "bup xstat".

Move the bits of xstat-cmd.py that generate the detailed metadata
representation to metadata.py and xstat.py to support their use from
both "bup xstat" and "bup meta -tvv".

Add size to detailed metadata description when available.

Change metadata "owner" to "user" everywhere to match stat(2), tar, etc.

Save metadata during "bup save".

Record metadata in a hidden/mangled file named .bup in each directory,
so that the metadata for /foo/ is stored in /foo/.bup, with the first
entry being the metadata for foo itself.  Record an empty index file
for each special file so that the index entries and .bupm entries
correspond.

For now, record "/" metadata only when there are no strip/graft
options.

Restore any metadata during "bup restore"; add "bup meta --edit".

Use "bup meta --edit" to test "bup restore" and the new tar/rsync-like
restoration behaviors.

Re-enable metadata tests by default since this is the metadata dev branch.

Disable the root-level test-meta.sh tests when the uname output
doesn't match Linux since they're not likely to work elsewhere right
now.

Defer errors when the restore target doesn't support relevant metadata.

When the restore target doesn't support POSIX1e ACLs, extended
attributes, or Linux attributes, handle the failures via add_error()
(i.e. defer them).

Test these cases by creating a loopback VFAT filesystem
(testfs-limited) and using it as a restore target.
