Remove support for FreeBSD 8 systems. These workarounds and ways of rescanning

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 sure we check for CAM_CDB_POINTER for all drivers. Also, for the
drivers I've touched, filter out CAM_CDB_PHYS.

CALLOUT_MPSAFE has lost its meaning since r141428, i.e., for more than ten
years for head. However, it is continuously misused as the mpsafe argument
for callout_init(9). Deprecate the flag and clean up callout_init() calls
to make them more consistent.

Prevent overflow issues in timeout processing

Previously, any timeout value for which (timeout * hz) will overflow the
signed integer, will give weird results, since callout(9) routines will
convert negative values of ticks to '1'. For unsigned integer overflow we
will get sufficiently smaller timeout values than expected.

Switch from callout_reset, which requires conversion to int based ticks
to callout_reset_sbt to avoid this.

Also correct isci to correctly resolve ccb timeout.

This was based on the original work done by Eygene Ryabinkin
<rea@freebsd.org> back in 5 Aug 2011 which used a macro to help avoid
the overlow.

Panic should the SCI framework ever request a pointer into the ccb's
data buffer for a ccb that is unmapped.

This case is currently not possible, since the SCI framework only
requests these pointers for doing SCSI/ATA translation of non-
READ/WRITE commands. The panic is more to protect against the
unlikely future scenario where additional commands could be unmapped.
