3c471b6588 bcachefs: convert bch_fs_flags to x-macro
Now we can print out filesystem flags in sysfs, useful for debugging
various "what's my filesystem doing" issues.

ad9c7992eb bcachefs: Kill btree_iter->journal_pos
For BTREE_ITER_WITH_JOURNAL, we memoize lookups in the journal keys, to
avoid the binary search overhead.

Previously we stashed the pos of the last key returned from the journal,
in order to force the lookup to be redone when rewinding.

Now bch2_journal_keys_peek_upto() handles rewinding itself when
necessary - so we can slim down btree_iter.

8a443d3ea1 bcachefs: Proper refcounting for journal_keys
The btree iterator code overlays keys from the journal until journal
replay is finished; since we're now starting copygc/rebalance etc.
before replay is finished, this is multithreaded access and thus needs
refcounting.

401585fe87 bcachefs: btree_journal_iter.c
Split out a new file from recovery.c for managing the list of keys we
read from the journal: before journal replay finishes the btree iterator
code needs to be able to iterate over and return keys from the journal
as well, so there's a fair bit of code here.
