kerneldump: remove physical argument from d_dumper

The physical address argument is essentially ignored by every dumper
method. In addition, the dump routines don't actually pass a real
address; every call to dump_append() passes a value of zero for
physical.

mfi: Remove unused devclass arguments to DRIVER_MODULE.

Fix "set but not used" warnings in mfi. The one in mfi.c:mfi_data_cb()
was a hidden but likely harmless mistake. The rest were just old code
that was OBE.

Extract eventfilter declarations to sys/_eventfilter.h

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"
in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header
pollution substantially.

EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).

As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions. The remainder of the patch addresses
adding appropriate includes to fix those files.

LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by
sys/mutex.h since r326106 (but silently protected by header pollution prior
to this change).

No functional change (intended). Of course, any out of tree modules that
relied on header pollution for sys/eventhandler.h, sys/lock.h, or
sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

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.

- Extend the prior commit to use the generic SCSI command building
function use that for JBOD and Thunderbolt disk write command. Now
we only have one implementation in mfi.
- Fix dumping on Thunderbolt cards. Polled IO commands do not seem to
be normally acknowledged by changing cmd_status to MFI_STAT_OK.
In order to get acknowledgement of the IO is complete, the Thunderbolt
command queue needs to be run through. I added a flag MFI_CMD_SCSI
to indicate this command is being polled and to complete the
Thunderbolt wrapper and indicate the result. This flag needs to be
set in the JBOD case in case if that us using Thunderbolt card.
When in the polling loop check for completed commands.
- Remove mfi_tbolt_is_ldio and just do the check when needed.
- Fix an issue when attaching of disk device happens when a device is
already scheduled to be attached but hasn't attached.
- add a tunable to allow raw disk attachment to CAM via:
hw.mfi.allow_cam_disk_passthrough=1
- fixup aborting of commands (AEN and LD state change). Use a generic
abort function and only wait the command being aborted not both.
Thunderbolt cards don't seem to abort commands so the abort times
out.
