When we map, unmap, or convert an extent in a file's data or attr
fork, schedule a respective update in the rmapbt. Previous versions
of this patch required a 1:1 correspondence between bmap and rmap,
but this is no longer true.
v2: Remove the 1:1 correspondence requirement now that we have the
ability to make interval queries against the rmapbt. Update the
commit message to reflect the broad restructuring of this patch.
Fix the bmap shift code to adjust the rmaps correctly.
v3: Use the deferred operations code to handle redo operations
atomically and deadlock free. Plumb in all five rmap actions
(map, unmap, convert extent, alloc, free); we'll use the first
three now for file data, and reflink will want the last two.
Add an error injection site to test log recovery.
