Move away from things like "lock if not locked" type code, require the
user has locked prior to geting to that point.
For now we warn if we are taking a lock we already had; however, this
should really be a failure point.
New requirements:
SETCFG -
not implicit commit - requires user has locked candidate DS and they
must unlock after
implicit commit - requires user has locked candidate and running DS
both locks will be unlocked on reply to the SETCFG
COMMITCFG -
requires user has locked candidate and running DS and they must unlock
after
rollback - this code now get both locks and then does an unlock and
early return thing on the adapter side. It needs to be un-special
cased in follow up work that would also include tests for this
functionality.

Effectively a massive search and replace of
`struct thread` to `struct event`. Using the
term `thread` gives people the thought that
this event system is a pthread when it is not

This is a first in a series of commits, whose goal is to rename
the thread system in FRR to an event system. There is a continual
problem where people are confusing `struct thread` with a true
pthread. In reality, our entire thread.c is an event system.
In this commit rename the thread.[ch] files to event.[ch].

The files converted in this commit either had some random misspelling or
formatting weirdness that made them escape automated replacement, or
have a particularly "weird" licensing setup (e.g. dual-licensed.)
This also marks a bunch of "public domain" files as SPDX License "NONE".

frrmod_load() attempts to dlopen() several possible paths
(constructed from its basename argument) until one succeeds.
Each dlopen() attempt may fail for a different reason, and
the important one might not be the last one. Example:
dlopen(a/foo): file not found
dlopen(b/foo): symbol "bar" missing
dlopen(c/foo): file not found
Previous code reported only the most recent error. Now frrmod_load()
describes each dlopen() failure.

Test uses staticd which required some C++ header protections.
Additionally, the test also runs in the ubuntu20 docker container as
grpc is supported there by the packaging system.
