The fuzzing actions are the longest actions in our CI right now. This
would be a good and happy thing if the bulk of the time was spent
fuzzing, but sadly the bulk of the time is spent doing build
preparations due to the nature of the ossfuzz docker setup.
Only two out of our 5 packages that contain fuzzers were ossfuzz
fuzzers, the rest are Go 1.18+ fuzzers. These two are converted to go
fuzzers, and then the github workflow is updated to just go test fuzz.
The action setup contains two separate steps for actions-cache, one that
handles the fuzzing corpus specifically so that we shuttle forward any
interesting corpus over time.
If the action fails, it will upload all the testdata/* directories,
which will include the data necessary to commit interesting cases for
permanent redistribution.

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

The //go:build syntax was introduced in Go 1.17:
https://go.dev/doc/go1.17#build-lines
gofmt has kept the +build and go:build lines in sync since
then, but enough time has passed. Time to remove them.
Done with:
perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build')

This lets clients quickly (sub-millisecond within a local LAN) map
from an ambiguous disco key to a node key without waiting for a
CallMeMaybe (over relatively high latency DERP).
Updates #3088
Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
* fix tailscale status for peers using discovery
* as part of that, pull out disco address selection into reusable
and testable discoEndpoint.addrForSendLocked
* truncate ping/pong logged hex txids in half to eliminate noise
* move a bunch of random time constants into named constants
with docs
* track a history of per-endpoint pong replies for future use &
status display
* add "send" and " got" prefix to discovery message logging
immediately before the frame type so it's easier to read than
searching for the "<-" or "->" arrows earlier in the line; but keep
those as the more reasily machine readable part for later.
Updates #483
Ping messages now go out somewhat regularly, pong replies are sent,
and pong replies are now partially handled enough to upgrade off DERP
to LAN.
CallMeMaybe packets are sent & received over DERP, but aren't yet
handled. That's next (and regular maintenance timers), and then WAN
should work.
