[RFC 2/6] bidi support: request_io_part

[Boaz Harrosh <bharrosh@panasas.com>]

The patch was probably too big and did not go through the mailing list.
I have compressed and attached it, is that OK or must I put it online somewhere?


- Extract all I/O members of struct request into a request_io_part member.
- Define API to access the I/O part
- Adjust block layer accordingly.
- Change all users to new API.

At this stage it is all still uni-directional but the intention is clear.
