meta_oodate: resolve relative paths

Fix a bug where meta_oodate fails to detect a missing file.
This can happen when the path name in .meta file is relative to
a subdir.

When faced with a relative path, call meta_resolve_path to
attempt to resolve it via
latestdir	the last dir we read/accessed
lcwd		the last dir we chdir to
cwd		the original cwd

If the path is "." just return lcwd.
If a relative path is not found, and should have been the target of
'W'rite, 'M'ove or 'L'ink, that we would normally add to missingFiles,
add $lcwd/$path to missingFiles - even if we guessed wrong, we will
make the target out-of-date as needed.

When removing a relative path from missingFiles due to a 'D'elete or 'M'ove
search using each of latestdir, lcwd and cwd as prefix.
