Brad Fitzpatrick a89d610a3d wgengine/tstun: move sync.Pool to package global
sync.Pools should almost always be packate globals, even though in this
case we only have exactly 1 TUN device anyway, so it matters less.
Still, it's unusual to see a Pool that's not a package global, so move it.

Brad Fitzpatrick 05a79d79ae control/controlclient: rewrite, test NetworkMap.ConciseDiffFrom
It stood out a lot in hello.ipn.dev's profiles for generating a lot of
garbage (and thus GC CPU).

Brad Fitzpatrick 2545575dd5 cmd/tailscale: default to not reporting daemon version
That's what I meant to do when I added "tailscale version" but
apparently I didn't.

David Anderson 189d86cce5 wgengine/router: don't use 88 or 8888 as table/rule numbers.
We originally picked those numbers somewhat at random, but with the idea
that 8 is a traditionally lucky number in Chinese culture. Unfortunately,
"88" is also neo-nazi shorthand language.

Use 52 instead, because those are the digits above the letters
"TS" (tailscale) on a qwerty keyboard, so we're unlikely to collide with
other users. 5, 2 and 52 are also pleasantly culturally meaningless.

ipn: load hostname in Start.
This prevents hostname being forced to os.Hostname despite override
when control is contacted for the first time after starting tailscaled.

Brad Fitzpatrick a6559a8924 wgengine/magicsock: run test DERP in mode where only disco packets allowed
So we don't accidentally pass a NAT traversal test by having DERP pick up our slack
when we really just wanted DERP as an OOB messaging channel.

wgengine/magicsock: make time.Sleep in runDerpReader respect cancellation.
Before this patch, the 250ms sleep would not be interrupted by context cancellation,
which would result in the goroutine sometimes lingering in tests (100ms grace period).

wgengine/magicsock: make receive from didCopy respect cancellation.
Very rarely, cancellation occurs between a successful send on derpRecvCh
and a call to copyBuf on the receiving side.
Without this patch, this situation results in <-copyBuf blocking indefinitely.

Brad Fitzpatrick a2267aae99 wgengine: only launch pingers for peers predating the discovery protocol
Peers advertising a discovery key know how to speak the discovery
protocol and do their own heartbeats to get through NATs and keep NATs
open. No need for the pinger except for with legacy peers.

David Anderson 45578b47f3 tstest/natlab: refactor PacketHandler into a larger interface.
The new interface lets implementors more precisely distinguish
local traffic from forwarded traffic, and applies different
forwarding logic within Machines for each type. This allows
Machines to be packet forwarders, which didn't quite work
with the implementation of Inject.

control/controlclient: eliminate race in loginGoal access.
This code is currently racy due to an incorrect assumption
that goal is never modified in-place, so does not require extra locking.
This change makes the assumption correct.
