Brad Fitzpatrick	0be26599ca	cmd/derper: refactor STUN path for testing, add serverSTUN benchmark ... Real goal is to eliminate some allocs in the STUN path, but that requires work in the standard library. See comments in #2783.

Brad Fitzpatrick	484b7fc9a3	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.
