David Anderson 76d99cf01a wgengine/filter: remove the Matches type.
It only served to obscure the underlying slice type without
adding much value.

David Anderson 54e6c3a290 version: use OSS repo's version when building.
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.

Brad Fitzpatrick a6c34bdc28 control/controlclient: also include our own profile (for when no self-owned peers)
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.

Brad Fitzpatrick 0e3048d8e0 control/controlclient: support delta userprofiles from control
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).

Brad Fitzpatrick 82f2fdc194 control/controlclient: adjust some logging point names
The previous code read too explicitly like log.Printf("I am here1"),
log.Printf("I am here2"). It still is with this change, but prettier, and
less subject to code rearranging order.

Brad Fitzpatrick 1819f6f8c8 control/controlclient: set MapRequest.ReadOnly on initial empty endpoint request
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).

Avery Pennarun 6332bc5e08 controlclient: print http errors if result code != 200.
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.

Brad Fitzpatrick 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.)

Brad Fitzpatrick 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.
