derp: reduce DERP memory use; don't require callers to pass in memory to use
...
The magicsock derpReader was holding onto 65KB for each DERP
connection forever, just in case.
Make the derp{,http}.Client be in charge of memory instead. It can
reuse its bufio.Reader buffer space.

derp: change NewClient constructor to an option pattern
...
(The NewMeshClient constructor I added recently was gross in

derp, cmd/derper: add frameWatchConns, framePeerPresent for inter-DERP routing
...
This lets a trusted DERP client that knows a pre-shared key subscribe
to the connection list. Upon subscribing, they get the current set
of connected public keys, and then all changes over time.
This lets a set of DERP server peers within a region all stay connected to
each other and know which clients are connected to which nodes.
