The bucket_gens array and gc_buckets array known their own size; we
should be using those members, and returning an error.

fsck_err() does a goto fsck_err on error; factor out check_fix_ptr() so
that our error label can drop our device ref.

Now explicitly allocate and free the buckets_nouse bitmap - this is
going to be used for online fsck.
To go RW when we haven't check allocations, we'll do a much slimmed down
version that just initializes the buckets_nouse bitmaps.

Currently, the reflink_p gc trigger does repair as well - turning a
reflink_p key into an error key if the reflink_v it points to doesn't
exist.
This won't work with online check/repair, because the repair path once
online will be subject to transaction restarts, but BTREE_TRIGGER_gc is
not idempotant - we can't run it multiple times if we get a transaction
restart.
So we need to split these paths; to do so this patch calls
check_fix_ptrs() by a new general path - a new trigger type,
BTREE_TRIGGER_check_repair.

If we hit an inconsistency when updating allocation information, we
don't want to fail the update if it's for a deletion - only if it's for
a new key.
Rename check_bucket_ref() -> bucket_ref_update() so we can centralize
the logic to do this.

We're working on potentially unifying bch2_check_bucket_ref() and
bch2_check_fix_ptrs() - or at least eliminating gratuitious differences.
Most immediately, there's a bunch of cleanups to be done regarding
BCH_DATA_stripe.

Combine iter/update/trigger/str_hash flags into a single enum, and
x-macroize them for a to_text() function later.
These flags are all for a specific iter/key/update context, so it makes
sense to group them together - iter/update/trigger flags were already
given distinct bits, this cleans up and unifies that handling.

Consolidate mark_superblock() and trans_mark_superblock(), like we did
with the other trigger paths.

Remove some duplication, and inconsistency between check_fix_ptrs and
the main ptr marking paths

The disk space accounting rewrite is splitting out accounting for each
replicas set - those are moving to btree keys, instead of percpu
counters.
This breaks bch2_trans_fs_usage_apply() up, splitting out the part we
will still need.

Split out base filesystem usage into its own type; prep work for
breaking up bch2_trans_fs_usage_apply().

Prep work for disk space accounting rewrite: we're going to want to use
a single callback for both of our current triggers, so we need to change
them to have the same type signature first.

This counter is redundant; it's simply the sum of BCH_DATA_stripe and
BCH_DATA_parity buckets.

This introduces bch2_bucket_sectors() and bch2_bucket_sectors_dirty(),
prep work for separately accounting stripe sectors.
