ceph: messenger and osdc changes for rbd
Allow the messenger to send/receive data in a bio. This is added
so that we wouldn't need to copy the data into pages or some other buffer
when doing IO for an rbd block device.
We can now have trailing variable sized data for osd
ops. Also osd ops encoding is more modular.
