For now, the server will only send v6 configuration to mapversion 8 clients
as part of an early-adopter program, while we verify that the functionality
is robust.

Addresses #964
Still to be done:
- Figure out the correct logging lines in util/systemd
- Figure out if we need to slip the systemd.Status function anywhere
else
- Log util/systemd errors? (most of the errors are of the "you cannot do
anything about this, but it might be a bad idea to crash the program if
it errors" kind)
Assistance in getting this over the finish line would help a lot.

final fixups
Signed-off-by: Christine Dodrill <me@christine.website>
After mapver 5's incremental netmap updates & user profiles, much of
the remaining bandwidth for streamed MapResponses were redundant,
unchanged PacketFilters. So make MapRequest.Version 6 mean that nil
means unchanged from the previous value.
Cache DNS results of earlier login.tailscale.com control dials, and use
them for future dials if DNS is slow or broken.
Fixes various issues with trickier setups with the domain's DNS server
behind a subnet router.

When building with redo, also include the git commit hash
from the proprietary repo, so that we have a precise commit
that identifies all build info (including Go toolchain version).
Add a top-level build script demonstrating to downstream distros
how to burn the right information into builds.
Adjust `tailscale version` to print commit hashes when available.
Fixes#841.

Fix from regression in previous commit
(0e3048d8e0) that was caught by e2e
tests.
In that previous commit, the user's own profile was omitted from the
NetworkMap in the case where the user only had one node.
I was going to make support for this advertised from the client, but
turns out only "tailscale status" even uses the UserProfiles field and
fails gracefully (omits that field) if a user profile for a user is
missing, so I think we can just reuse the DeltaPeers field from the
client to ask the control server to also delta encode the user
profiles.
For the few users running 1.1.x (unstable) versions between DeltaPeers
support (1.1.82) and this (~1.1.541), they'll just sometimes have
missing names in "tailscale status --json" or "tailscale status --web"
(the only places the UserProfile is used).
On startup, clients do a MapRequest with empty endpoints while they
learn the DERP map to discover the STUN servers they then query to
learn their endpoints.
Set MapRequest.ReadOnly on those initial queries to not broadcast the
empty endpoints out to peers. The read results will come a half second
later (or less).
Updates tailscale/corp#557
Turns out for the particular error I was chasing, it actually returns
200 and zero data. But this code mirrors the same check in the map
poll, and is the right thing to do in the name of future debugging.

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.)

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.
Updates #483
As part of disabling background STUN packets when idle, we want an
emergency override switch to turn it back on, in case it interacts
poorly in the wild. We'll send that via control, but we'll want to
plumb it down to magicsock via NetworkMap.
