improvements to mpt_sas debug logging and mdb module
Along with the 12G support for mpt_sas, Andy Giles created a set of changes to improve the mpt_sas debug logging to be more useful, and he also made improvements to the mdb module for mpt_sas.

The changes include a few bits of cleanup in the existing messages mpt_sas prints, plus a few new messages. The mdb module received a bit of cleanup, and now prints additional information. The flag to display command slots (-s) does now work, although only when used in kmdb and on core dumps.
Also, Andy added debug log ring buffer, only active in debug mode. Debug messages can be logged to this buffer, a new tunable selects which messages are logged. This should have less impact on a system than printing them to the console and system log. The debug log ring buffer can be viewed with mdb ::mptsas.
