libceph: separate read and write data
An osd request defines information about where data to be read should be placed as well as where data to write comes from. Currently these are represented by common fields. Keep information about data for writing separate from data to be read by splitting these into data_in and data_out fields. This is the key patch in this whole series, in that it actually identifies which osd requests generate outgoing data and which generate incoming data. It's less obvious (currently) that an osd CALL op generates both outgoing and incoming data; that's the focus of some upcoming work.
