r308217:
Add a fallback to the device mapper logic.  We've seen systems in the field
that are apparently misconfigured by the manufacturer and cause the mapping
logic to fail.  The fallback allows drive numbers to be assigned based on the
PHY number that they're attached to.  Add sysctls and tunables to overrid
this new behavior, but they should be considered only necessary for debugging.

r308301:
Record the LogInfo field when reporting the IOCStatus.  Helps in
debugging errors.

r311958:
Print out the number of queues/MSIx vectors.

r312437:
Rework the debug print API. Event printing no longer gets special handling.
All of the printing from the tables file now has wrappers so that the
handling is cleaner and it's possible to print something out (say, during
development) without having to fight the global debug flags. This re-org
will also make it easier to have the tables be compiled out at build time
if desired.

Other than fixing some minor bugs, there are no user-visible changes from
this change

r318188:
Improve error messages during command timeout for the mpr and mps
drivers.

Sponsored by:	Netflix

r318427:
Add tri-mode support (SAS/SATA/PCIe).

This includes NVMe device support and adds support for the following adapters:
    SAS 3408
    SAS 3416
    SAS 3508
    SAS 3516
    SAS 3616
    SAS 3708
