This set of patches culminates in providing layered
write functionality for rbd clone images. Until the
feature bits get enabled, most of this code is not
yet activated. But it has been tested and it's
ready for review. The feature will be enabled soon,
after a few more things get cleaned up to prepare
for it.

[PATCH] libceph: fix two messenger bugs
Two bugs, two improvements.
[PATCH] libceph: support pages for class request data
This just defines a function that allows a page array
to be specified for the data to be written by an
object class method.
[PATCH 1/4] rbd: define separate read and write format funcs
[PATCH 2/4] rbd: encapsulate submission of image object requests
[PATCH 3/4] rbd: define zero_pages()
[PATCH 4/4] rbd: support page array image requests
The first two of these are just cleanups. The second two
add some functionality to allow image requests to use
page arrays for their object data.
[PATCH 1/2] rbd: implement full object parent reads
[PATCH 2/2] rbd: issue a copyup for layered writes
These last two finally implement the layered copyup
functionality. The first is sort of a half step, to
break up the review into smaller pieces.
