[PATCHSET v29.0 37/40] xfs_scrub_all: automatic media scan service

Hi all,

Now that we've completed the online fsck functionality, there are a few
things that could be improved in the automatic service. Specifically,
we would like to perform a more intensive metadata + media scan once per
month, to give the user confidence that the filesystem isn't losing data
silently. To accomplish this, enhance xfs_scrub_all to be able to
trigger media scans. Next, add a duplicate set of system services that
start the media scans automatically.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

This has been running on the djcloud for months with no problems. Enjoy!
Comments and questions are, as always, welcome.
