These accidentally make the tag syntax more flexible than was intended,
which will create forward compatibility problems later. Let's go back
to the old stricter parser.

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.

This partially (but not yet fully) migrates Windows to tailscaled's
StateStore storage system.
This adds a new bool Pref, ForceDaemon, defined as:
// ForceDaemon specifies whether a platform that normally
// operates in "client mode" (that is, requires an active user
// logged in with the GUI app running) should keep running after the
// GUI ends and/or the user logs out.
//
// The only current applicable platform is Windows. This
// forced Windows to go into "server mode" where Tailscale is
// running even with no users logged in. This might also be
// used for macOS in the future. This setting has no effect
// for Linux/etc, which always operate in daemon mode.
Then, when ForceDaemon becomes true, we now write use the StateStore
to track which user started it in server mode, and store their prefs
under that key.
The ipnserver validates the connections/identities and informs that
LocalBackend which userid is currently in charge.
The GUI can then enable/disable server mode at runtime, without using
the CLI.
But the "tailscale up" CLI was also fixed, so Windows users can use
authkeys or ACL tags, etc.
Updates #275
When the network link changes, existing UDP sockets fail immediately
and permanently on macOS.
The forwarder set up a single UDP conn and never changed it.
As a result, any time there was a network link change,
all forwarded DNS queries failed.
To fix this, create a new connection when send requests
fail because of network unreachability.
This change is darwin-only, although extended it to other platforms
should be straightforward.

Part of unforking our winipcfg-go and using upstream (#760), move our
additions into our repo. (We might upstream them later if upstream has
interest)
Originally these were:
@apenwarr: "Add ifc.SyncAddresses() and SyncRoutes()."
609dcf2df5
@bradfitz: "winipcfg: make Interface.AddRoutes do as much as possible, return combined error"
e9f93d53f3
@bradfitz: "prevent unnecessary Interface.SyncAddresses work; normalize IPNets in deltaNets"

We depend on DERP for NAT traversal now[0] so disabling it entirely can't
work.
What we'll do instead in the future is let people specify
alternate/additional DERP servers. And perhaps in the future we could
also add a pref for nodes to say when they expect to never need/want
to use DERP for data (but allow it for NAT traversal communication).
But this isn't the right pref and it doesn't work, so delete it.
Fixes#318

This change is to restore /etc/resolv.conf after tailscale down is called. This is done by setting the dns.Manager before errors occur. Error collection is also added.
Fixes#723
Also remove rebinding logic from the windows router. Magicsock will
instead rebind based on link change signals.
