Some of the xfs source files are missing header includes, so add them
back. Sparse complains about non-static functions that don't have a
forward declaration anywhere.

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.

Teach online scrub how to check the filesystem summary counters. We use
the incore delalloc block counter along with the incore AG headers to
compute expected values for fdblocks, icount, and ifree, and then check
that the percpu counter is within a certain threshold of the expected
value. This is done to avoid having to freeze or otherwise lock the
filesystem, which means that we're only checking that the counters are
fairly close, not that they're exactly correct.

Skip cross-referencing with a btree if the health report tells us that
it's known to be bad. This should reduce the dmesg spew considerably.

Now that we have the ability to track sick metadata in-core, make scrub
and repair update those health assessments after doing work.
