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.)

e6b84f2159 all: make client use server-provided DERP map, add DERP region support 
Instead of hard-coding the DERP map (except for cmd/tailscale netcheck
for now), get it from the control server at runtime.

And make the DERP map support multiple nodes per region with clients
picking the first one that's available. (The server will balance the
order presented to clients for load balancing)

This deletes the stunner package, merging it into the netcheck package
instead, to minimize all the config hooks that would've been
required.

Also fix some test flakes & races.

Fixes #387 (Don't hard-code the DERP map)
Updates #388 (Add DERP region support)
Fixes #399 (wgengine: flaky tests)

9d1f48032a cmd/tailscale: add --advertise-tags option. 
These will be used for dynamically changing the identity of a node, so
its ACL rights can be different from your own.

Note: Not all implemented yet on the server side, but we need this so
we can request the tagged rights in the first place.

65fbb9c303 wgengine/filter: support subnet mask rules, not just /32 IPs. 
This depends on improved support from the control server, to send the
new subnet width (Bits) fields. If these are missing, we fall back to
assuming their value is /32.

Conversely, if the server sends Bits fields to an older client, it will
interpret them as /32 addresses. Since the only rules we allow are
"accept" rules, this will be narrower or equal to the intended rule, so
older clients will simply reject hosts on the wider subnet (fail
closed).

With this change, the internal filter.Matches format has diverged
from the wire format used by controlclient, so move the wire format
into tailcfg and convert it to filter.Matches in controlclient.
