r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.
Mark all low hanging fruits as MPSAFE.

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.
No functional change intended.
Also - allow driver specific bits to be added, rather than just net80211.
This still isn't as useful as it should be by default; it needs to
be a standalone struct/instance so it can be done before net80211
registration occurs, and it can log per-device items.
But, it's getting there.
* revert a local path change that shouldn't have made it to the commit
* fix some indenting/wrapping
* Fix the ale data copy - i should be copying into the ale data pointer,
not over the ale entry itself.
This is destined to be a lightweight and optional set of ALQ
probes for debugging events which are just impossible to debug
with printf/log (eg packet TX/RX handling; AMPDU handling.)
The probes and operations themselves will appear in subsequent
commits.
