This patch introduces
- bpos_eq()
- bpos_lt()
- bpos_le()
- bpos_gt()
- bpos_ge()
and equivalent replacements for bkey_cmp().
Looking at the generated assembly these could probably be improved
further, but we already see a significant code size improvement with
this patch.

Long ago, bkey_unpack_key() was added to bset.h instead of bkey.h
because bkey.h didn't include btree_types.h, which it needs for the
compiled unpack function.
This patch finally moves it to the proper location.

We now update the alloc info (bucket sector counts) atomically with
journalling the update to the interior btree nodes, and we also set new
btree roots atomically with the journalled part of the btree update.
