Add a xbitmap_hweight helper function so that we can get rid of the
open-coded loop.

Shorten the name of xfs_bitmap to xbitmap since the scrub bitmap has
nothing to do with the libxfs bitmap.

xfs_iread_extents open-codes everything in xfs_btree_visit_blocks, so
refactor the btree helper to be able to iterate only the records on
level 0, then port iread_extents to use it.

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.

As mentioned previously, the xrep_extent_list basically implements a
bitmap with two functions: set and disjoint union. Rename all these
functions to xfs_bitmap to shorten the name and make it more obvious
what we're doing.

Move the xrep_extent_list code into a separate file. Logically, this
data structure is really just a clumsy bitmap, and in the next patch
we'll make this more obvious. No functional changes.
