libata update

A ton of SATA work in the past few weeks, but not a lot terribly new in this update. The update is mainly to rediff against the latest 2.4 and 2.6 kernels. Note that this does not include experimental patches. Notably absent are

* lba48 (large transfer) requests
* splitting up Promise driver into sata_promise (tx2/tx4) and sata_sx4 (sx4) drivers.
* adding better flush-cache / writeback caching support

The above are all experimental patches I have locally.

Finally, per user requests, I have started posting the associated changelog as well.

Drivers for SATA-2 controllers have been in development, and should be making their appearance soon.
