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).

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.

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.

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.

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.

tstun: remove buggy-looking log line. 
This log line looks buggy, even though lacking a filter is expected during bringup.
We already know if we forget to SetFilter: it breaks the magicsock test,
