sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

- Make tables, device ID strings etc const. This includes #ifdef'ing 0
aac_command_status_table, which is actually unused since r111532.
While at it, make aac_if a pointer to the now const interface tables
instead of copying them over to the softc (this alone already reduces the
size of aac.ko on amd64 by ~1 KiB).
- Remove redundant softc members.
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.
- Remove redundant bzero(9)'ing of the softc.
- Use pci_enable_busmaster(9) instead of duplicating it.
- Remove redundant checking for PCIM_CMD_MEMEN (resource allocation will
just fail).
- Canonicalize the error messages in case of resource allocation failures.
- Add support for using MSI instead of INTx, controllable via the tunable
hw.aac.enable_msi (defaulting to on).

Update to current version of head.

Merge svn+ssh://svn.freebsd.org/base/head@206571

Use enums in the aac_command_status_table rather than duplicating the same
values in two places.

Sync some minor items with the upstream driver. Should have no functional
change.

Mega Update to the aac driver to support a whole new family of cards and
the modified interface that they use. Changes include:

- Register a different interrupt handler for the new interface. This

Mega Update to the aac driver to support a whole new family of cards and
the modified interface that they use. Changes include:

- Register a different interrupt handler for the new interface. This one is
INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs.
- Add an event registration and callback mechanism for the ioctl and CAM
modules can know when a resource shortage clears. This condition was
previously fatal in CAM due to programming oversights.
- Fix locking to play better with newbus.
- Provide access methods for talking to cards with the NEWCOMM interface.
- Fix up the CAM module to be better suited for dealing with newer firmware
on the PERC Si/Di series that requires talking to plain SCSI via aac.
- Add a whole slew of new PCI Id's.

Thanks to Adaptec for providing an initial version of this work and for
answering countless questions about it. There are still some rough edges in
this, but it works well enough to commit and test for now.

Add functionality and fix bugs so the driver will work with soon-to-be
released management apps.

1. Implement poll(). This will check for queued aif's so that a
subsequent ioctl call to retrieve the next aif will not block.
2. Don't catch signals when sleeping on a fib sent from userland. This
causes a race and panic due to the pthread context switcher waking
up the tsleep at inopportune times.
3. Fix some whitespace nits.
