Introduce a new file /proc//blockio (and equivalently per-thread
/proc//task//blockio files) to export per block device i/o statistics
of each process to userspace applications.

The objective of this patch is to provide an efficient method to quickly
identify the top i/o consumers on specific block devices and, more in general,
to collect more detailed informations about specific block device usage.

See the documentation (PATCH 1/4) for more information.

Tested against 2.6.27-rc1-mm1.
