[PATCH 01/32] block/fs: add REQ_OP definitions.

[mchristi@redhat.com]

From: Mike Christie <mchristi@redhat.com>

This patch adds definitions for request/bio operations which
will be used in the next patches.

In the initial patches the REQ_OPs match the REQ ones for compat reasons
while all the code is converted in this set. In the last patches
that will be removed.
