e6b84f2159 all: make client use server-provided DERP map, add DERP region support
Instead of hard-coding the DERP map (except for cmd/tailscale netcheck
for now), get it from the control server at runtime.

And make the DERP map support multiple nodes per region with clients
picking the first one that's available. (The server will balance the
order presented to clients for load balancing)

This deletes the stunner package, merging it into the netcheck package
instead, to minimize all the config hooks that would've been
required.

Also fix some test flakes & races.

Fixes #387 (Don't hard-code the DERP map)
Updates #388 (Add DERP region support)
Fixes #399 (wgengine: flaky tests)

af9328c1b7 log rate limiting: reformat limiter messages, and use nonempty burst size.
- Reformat the warning about a message being rate limited to print the
  format string, rather than the formatted message. This helps give a
  clue what "type" of message is being limited.

- Change the rate limit warning to be [RATE LIMITED] in all caps. This
  uses less space on each line, plus is more noticeable.

- In tailscaled, change the frequency to be less often (once every 5
  seconds per format string) but to allow bursts of up to 5 messages.
  This greatly reduces the number of messages that are rate limited
  during startup, but allows us to tighten the limit even further during
  normal runtime.

Implement rate limiting on log messages (#356)
Implement rate limiting on log messages

Addresses issue #317, where logs can get spammed with the same message
nonstop. Created a rate limiting closure on logging functions, which
limits the number of messages being logged per second based on format
string. To keep memory usage as constant as possible, the previous cache
purging at periodic time intervals has been replaced by an LRU that
discards the oldest string when the capacity of the cache is reached.

b4897e7de8 controlclient/netmap: write our own b.ConciseDiffFrom(a) function.
This removes the need for go-cmp, which is extremely bloaty so we had
to leave it out of iOS. As a result, we had also left it out of macOS,
and so we didn't print netmap diffs at all on darwin-based platforms.
Oops.

As a bonus, the output format of the new function is way better.

Minor oddity: because I used the dumbest possible diff algorithm, the
sort order is a bit dumb. We print all "removed" lines and then print
all "added" lines, rather than doing the usual diff-like thing of
interspersing them. This probably doesn't matter (maybe it's an
improvement).

5bc632271b Introduce a state store to LocalBackend.
The store is passed-in by callers of NewLocalBackend and
ipnserver.Run, but currently all callers are hardcoded to
an in-memory store. The store is unused.

21280ca2d1 Make ipn.Options.Prefs a pointer.
This is a prelude to making it truly optional, once state
management has moved into the backend. For now though, it's
still required. This change is just isolating the bubbling-up
of the pointerification into other layers.

f6f154193f Remove LoginFlags from Backend options.
- It was only used in one currently-unused client.
- It's an imperative command, not a configuration setting.
- The LoginFlags stuff in controlclient feels like it needs
  a refactor anyway.

I'll put this logic back once ipnd owns its state and Backend
commands reflect that.

3d5ef74f26 tailscaled: add tunnel name and port flags
OpenBSD tunnel names are prefixed with `tun`.

Controlling the port allows for deterministic configuration of firewall
rules (using `pf` in this case).

ea11d58e96 debian: fix changelog generation.
It seems changelog generation got broken by moving the code between
corp and OSS repos, because one of the commit SHAs doesn't have an
associated tag.

In the interest of fixing the build, and because we're not yet trying
to upstream the debian package, I fixed this by allowing hash-based
versions to show up in the changelog. This maybe wrong from a
debian standards perspective, but for our current point in life
it'll work until we learn to do it better.
