[RFC C 2/5] libosd: Rename osd_req_write/read to osd_req_write/read_old

[Boaz Harrosh <bharrosh@panasas.com>]

In an attempt to not use bio(s) at the initiator, we want
to convert to something else (array of page pointers).
This patch renames the current bio API to xxx_old.

The next patch will implement the new API.
After all Kernel users (exofs) will convert to the new API
The old can be removed.

The API is marked __deprecated and will spew warnings until
conversion is done.

Note that this patch patches all users (exofs)
