CWARNFALGS.$file centrally so we don't have to have it in all the
places. Remove a few warning flags that are no longer needed.
Also, always use -Wno-unknown-pragma to (hopefully temporarily) work
around #pragma ident in debug.h in the opensolaris code. Remove some
stale warning suppression that's no longer necessary.

Because the driver is obtained from upstream, we don't want to modify
it; just silence the warning instead, it is harmless.

This involves significant changes to the mps(4) driver, but is not a
complete rewrite.
Some of the changes in this version of the driver:
- Integrated RAID (IR) support.
- Support for WarpDrive controllers.
- Support for SCSI protection information (EEDP).
- Support for TLR (Transport Level Retries), needed for tape drives.
- Improved error recovery code.
- ioctl interface compatible with LSI utilities.
mps.4: Update the mps(4) driver man page somewhat for the driver
changes. The list of supported hardware still needs to be
updated to reflect the full list of supported cards.
conf/files: Add the new driver files.
mps/mpi/*: Updated version of the MPI header files, with a BSD style
copyright.
mps/*: See above for a description of the new driver features.
modules/mps/Makefile:
Add the new mps(4) driver files.

Bring in a driver for the LSI Logic MPT2 6Gb SAS controllers.
This driver supports basic I/O, and works with SAS and SATA drives and
expanders.
Basic error recovery works (i.e. timeouts and aborts) as well.
Integrated RAID isn't supported yet, and there are some known bugs.
So this isn't ready for production use, but is certainly ready for
testing and additional development. For the moment, new commits to this
driver should go into the FreeBSD Perforce repository first
(//depot/projects/mps/...) and then get merged into -current once
they've been vetted.
This has only been added to the amd64 GENERIC, since that is the only
architecture I have tested this driver with.
