dm-cache: block level disk cache target for device mapper

This is the first cut of a device-mapper target which provides a write-back
or write-through block cache.  It is intended to be used in conjunction with
remote block devices such as iSCSI or ATA-over-Ethernet, particularly in
cluster situations.

In performance tests with iSCSI, gave peformance improvements of 2-10x that
of iSCSI alone when Postmark or Bonnie loads were applied from 8 clients to
a single server.  Evidence suggests even greater differences on larger
clusters.  A detailed performance analysis will be vailable shortly via a
technical report on IBM's CyberDigest.

This module was developed during an intership at IBM Research by
Ming Zhao.  Please direct comments to both Ming and myself.
