Introduce rq_for_each_segment replacing rq_for_each_bio
...
Every usage of rq_for_each_bio wraps a usage of
bio_for_each_segment, so these can be combined into
rq_for_each_segment.
We define "struct req_iterator" to hold the 'bio' and 'index' that
are needed for the double iteration.

[BLOCK] Get rid of request_queue_t typedef
...
Some of the code has been gradually transitioned to using the proper
struct request_queue, but there's lots left. So do a full sweet of
the kernel and get rid of this typedef and replace its uses with
the proper type.

ps3: Disk Storage Driver
...
Add a Disk Storage Driver for the PS3:
- Implemented as a block device driver with a dynamic major
- Disk names (and partitions) are of the format ps3d%c(%u)
- Uses software scatter-gather with a 64 KiB bounce buffer as the hypervisor
doesn't support scatter-gather
