The notable changes are:
- instead of explicitly stat'ing the object to see if it exists before
issuing the write, send the write optimistically along with the stat
in a single OSD request
- zero copyup optimization
- all object requests are associated with an image request and have
a valid ->img_request pointer; there are no standalone (!IMG_DATA)
object requests anymore
- code is structured as a state machine (vs a bunch of callbacks with
implicit state)
