XFS stopped using current->journal_info in commit f2e812c1522d ("xfs:
don't use current->journal_info"), so there is no point in saving and
restoring it.

xchk_trans_alloc_empty can't return errors, so return the allocated
transaction directly instead of an output double pointer argument.

All callers of xrep_reap_metadir_fsblocks need to fix up the metabtree
reservation, otherwise they'd leave the reservations in an incoherent
state. Move the call to xrep_reset_metafile_resv into
xrep_reap_metadir_fsblocks so it always is taken care of, and remove
now superfluous helper functions in the callers.

Walk the realtime refcount btree to find the CoW staging extents when
we're rebuilding the realtime rmap btree.

Hook the regular realtime rmap code when an rtrmapbt repair operation is
running so that we can unlock the AGF buffer to scan the filesystem and
keep the in-memory btree up to date during the scan.

Create an in-memory btree of rmap records instead of an array. This
enables us to do live record collection instead of freezing the fs.

Repair the realtime rmap btree while mounted. Similar to the regular
rmap btree repair code, we walk the data fork mappings of every realtime
file in the filesystem to collect reverse-mapping records in an xfarray.
Then we sort the xfarray, and use the btree bulk loader to create a new
rtrmap btree ondisk. Finally, we swap the btree roots, and reap the old
blocks in the usual way.
