904a91038a tailcfg: add MapRequest.ReadOnly and OmitPeers; remove DebugForceDisco 
DebugForceDisco was a development & safety knob during the the transition
to discovery. It's no longer needed.

Add MapRequest.ReadOnly to prevent clients needing to do two
peer-spamming MapRequest at start-up.

This only adds the field, not the use of the field. (The control server
needs to support it first.)

6298018704 control/controlclient: print disco keys NetworkMap diffs (debug change only) 
NetworkMap text diffs being empty were currently used to short-circuit
calling magicsock's SetNetworkMap (via Engine.SetNetworkMap), but that
went away in c7582dc2 (0.100.0-230)

Prior to c7582dc2 (notably, in 0.100.0-225 and below, down to
0.100.0), a change in only disco key (as when a node restarts) but
without endpoint changes (as would happen for a client not behind a
NAT with random ports) could result in a "netmap diff: (none)" being
printed, as well as Engine.SetNetworkMap being skipped, leading to
broken discovery endpoints.

c7582dc2 fixed the Engine.SetNetworkMap skippage.

This change fixes the "netmap diff: (none)" print so we'll actually see when a peer
restarts with identical endpoints but a new discovery key.

a975e86bb8 wgengine/magicsock: add new endpoint type used for discovery-supporting peers 
This adds a new magicsock endpoint type only used when both sides
support discovery (that is, are advertising a discovery
key). Otherwise the old code is used.

So far the new code only communicates over DERP as proof that the new
code paths are wired up. None of the actually discovery messaging is
implemented yet.

Support for discovery (generating and advertising a key) are still
behind an environment variable for now.

b8edb7a5e9 control/controlclient: add Debug field to NetworkMap 
As part of disabling background STUN packets when idle, we want an

poorly in the wild. We'll send that via control, but we'll want to
plumb it down to magicsock via NetworkMap.
