When using a custom http port like 8080, this was resulting in a
constructed hostname of `host.tailnet.ts.net:8080.tailnet.ts.net` when
looking up the serve handler. Instead, strip off the port before adding
the MagicDNS suffix.
Also use the actual hostname in `serve status` rather than the literal
string "host".

We were never resetting the backoff in streaming mapResponses.
The call to `PollNetMap` always returns with an error. Changing that contract
is harder, so manually reset backoff when a netmap is received.

When performing a fallback DNS query, run the recursive resolver in a
separate goroutine and compare the results returned by the recursive
resolver with the results we get from "regular" bootstrap DNS. This will
allow us to gather data about whether the recursive DNS resolver works
better, worse, or about the same as "regular" bootstrap DNS.

This change removes the noV4/noV6 check from addrForSendWireGuardLocked.
On Android, the client panics when reaching `rand.Intn()`, likely due to
the candidates list being containing no candidates. The suspicion is
that the `noV4` and the `noV6` are both being triggered causing the
loop to continue.

This change introduces tstime.NewClock and tstime.ClockOpts as a new way
to construct tstime.Clock. This is a subset of #8464 as a stepping stone
so that we can update our internal code to use the new API before making
the second round of changes.

This commit makes it so that it prints out the package information

Calling both mono.Now() and time.Now() is slow and
leads to unnecessary precision errors.
Instead, directly compute mono.Time relative to baseMono and baseWall.
This is the opposite calculation as mono.Time.WallTime.

The panicLogWriter is too strict, and any panics that occur
get wrapped up in quotes. This makes it so that it will allow
panics to continue writing to Stderr without going through
logger.Logf.
