If 'changelog' is enabled and 'changelog.capture-del-path' option is on
it calls 'resolve_pargfid_to_path' which modifies 'pargfid' sent by
caller.  'changelog_unlink' calls this routine directly with
'loc->pargfid' resulting it being modified and point to root instead of
actual pargfid. This is a nasty bug and could cause the deletion of
entry on root directory instead on actual parent when 'loc->path' is
not present.  Hence this fix to make 'pargfid' a const pointer and
'resolve_pargfid' to work on copy of pargfid.

Glusterfind session creation enables these options by default to
capture deleted entry path in changelog.

Thanks Pranith for root causing this.

On Linux systems we should use the libuuid from the distribution and not
bundle and statically link the contrib/uuid/ bits.

libglusterfs/src/compat-uuid.h has been introduced and should become an
abstraction layer for different UUID APIs. Non-Linux operating systems
should implement their compatibility layer there.

Once all operating systems have an implementation in compat-uuid.h, we
can remove contrib/uuid/ from the repository completely.
