Implement very basic ALQ logging for net80211. 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.

sys: general 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. No functional change intended.

[net80211] extend the net80211 ALQ code to support variable payloads. 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.

Add the thread id to the net80211 alq records. This will (hopefully) aid in debugging concurrency related issues.
