* cmd/tailscale/cli: make `tailscale update` query `softwareupdate`
Even on macOS when Tailscale was installed via the App Store, we can check for
and even install new versions if people ask explicitly. Also, warn if App Store
AutoUpdate is not turned on.
Updates #6995
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".

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.

On some platforms (notably macOS and iOS) we look up the default
interface to bind outgoing connections to. This is both duplicated
work and results in logspam when the default interface is not available
(i.e. when a phone has no connectivity, we log an error and thus cause
more things that we will try to upload and fail).
Fixed by passing around a netmon.Monitor to more places, so that we can
use its cached interface state.

Uses the hooks added by tailscale/go#45 to instrument the reads and

convention is to use "<package>.<type>:<label>" as the annotation for
the responsible code path.
Enabled on iOS, macOS and Android only, since mobile platforms are the
ones we're most interested in, and we are less sensitive to any
throughput degradation due to the per-I/O callback overhead (macOS is
also enabled for ease of testing during development).
For now just exposed as counters on a /v0/sockstats PeerAPI endpoint.
We also keep track of the current interface so that we can break out

to be able to delete the "/tka" dir if it exists.
