Before synctest, timers was needed to allow the events to flow into the
test bus. There is still a timer, but this one is not derived from the
test deadline and it is mostly arbitrary as synctest will render it
practically non-existent.
With this approach, tests that do not need to test for the absence of
events do not rely on synctest.

Android's altNetInterfaces implementation now returns net.IPAddr
types which netmon wasn't handling.

This makes things work slightly better over the eventbus.
Also switches ipnlocal to use the event over the eventbus instead of the
direct callback.

In prep for most of the package funcs in net/interfaces to become
methods in a long-lived netmon.Monitor that can cache things. (Many
of the funcs are very heavy to call regularly, whereas the long-lived
netmon.Monitor can subscribe to things from the OS and remember
answers to questions it's asked regularly later)

This removes a lot of API from net/interfaces (including all the
filter types, EqualFiltered, active Tailscale interface func, etc) and
moves the "major" change detection to net/netmon which knows more
about the world and the previous/new states.

We're using it in more and more places, and it's not really specific to
our use of Wireguard (and does more just link/interface monitoring).
Also removes the separate interface we had for it in sockstats -- it's
a small enough package (we already pull in all of its dependencies
via other paths) that it's not worth the extra complexity.
