When we decide to mark an inode sick, clear the DONTCACHE flag so that
the incore inode will be kept around until memory pressure forces it out
of memory. This increases the chances that the sick status will be
caught by someone compiling a health report later on.

for_each_perag_tag() is defined in xfs_icache.c for local use.
Promote this to xfs_ag.h and define equivalent iteration functions
so that we can use them to iterate AGs instead to replace open coded
perag walks and perag lookups.
We also convert as many of the straight forward open coded AG walks
to use these iterators as possible. Anything that is not a direct
conversion to an iterator is ignored and will be updated in future
commits.

They are AG functions, not superblock functions, so move them to the
appropriate location.

Introduce a new version of the in-core bulkstat structure that supports
our new v5 format features. This structure also fills the gaps in the
previous structure. We leave wiring up the ioctls for the next patch.

There are many, many xfs header files which are included but
unneeded (or included twice) in the xfs code, so remove them.
nb: xfs_linux.h includes about 9 headers for everyone, so those
explicit includes get removed by this. I'm not sure what the
preference is, but if we wanted explicit includes everywhere,
a followup patch could remove those xfs_*.h includes from
xfs_linux.h and move them into the files that need them.
Or it could be left as-is.

If we know the filesystem metadata isn't healthy during unmount, we want
to encourage the administrator to run xfs_repair right away. We can't
do this if BAD_SUMMARY will cause an unclean log unmount to force
summary recalculation, so turn it off if the fs is bad.

Add the necessary in-core metadata fields to keep track of which parts
of the filesystem have been observed and which parts were observed to be
unhealthy, and print a warning at unmount time if we have unfixed
problems.
