The windows key timeout is longer than the wgengine watchdog timeout,
which means we never reach the timeout, instead the process exits.
Reduce the timeout so if we do hit it, at least the process continues.

On Win10, there's a hardcoded GUID and this works.
On Win7, this GUID changes and we need to ask the tun for its
LUID and convert that from the GUID.
This commit uses the computed GUID that is placed in InterfaceName.
Diagnosed by Jason Donnenfeld. (Thanks!)
Log levels can now be specified with "[v1] " or "[v2] " substrings
that are then stripped and filtered at the final logger. This follows
our existing "[unexpected]" etc convention and doesn't require a
wholesale reworking of our logging at the moment.
cmd/tailscaled then gets a new --verbose=N flag to take a log level
that controls what gets logged to stderr (and thus systemd, syslog,
etc). Logtail is unaffected by --verbose.
This commit doesn't add annotations to any existing log prints. That
is in the next commit.

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.

In practice, we already provide IPv6 endpoint addresses via netcheck,
and that address is likely to match a local address anyway (i.e. no NAT66).
The comment at that piece of the code mentions needing to figure out a
good priority ordering, but that only applies to non-active-discovery
clients, who already don't do anything with IPv6 addresses.

Lazy wg configuration now triggers if a peer has only endpoint
addresses (/32 for IPv4, /128 for IPv6). Subnet routers still
trigger eager configuration to avoid the need for a CIDR match
in the hot packet path.

This caused some confusion in issue #460, since usually raw format
strings aren't printed directly. Hopefully by directly logging that
they are intended to be raw format strings, this will be more clear.
Rate limited format strings now look like:
[RATE LIMITED] format string "control: sendStatus: %s: %v"
Closes#460.

The previous code used a lot of whole-function variables and shared
behavior that only triggered based on prior action from a single codepath.
Instead of that, move the small amounts of "shared" code into each switch
case.

Before, tailscaled would log every 10 seconds when the periodic noteRecvActivity
call happens. This is noisy, but worse it's misleading, because the message
suggests that the disco code is starting a lazy config run for a missing peer,
whereas in fact it's just an internal piece of keepalive logic.
With this change, we still log when going from 0->1 tunnel for the peer, but
not every 10s thereafter.

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

Upgrading staticcheck upgraded golang.org/x/sync
(one downside of mixing our tools in with our regular go.mod),
which introduced a new dependency via
https://go-review.googlesource.com/c/sync/+/251677
That CL could and probably should be written without runtime/debug,
but it's not clear to me that that is better at this moment
than simply accepting the additional package as a dependency.

These ignore built files that don't exist anymore, and just serve
to clutter up the .gitignore file. (I was initially confused when
I saw those lines, since I (correctly) thought that the only
Tailscale binaries were tailscale and tailscaled):
- taillogin was removed in d052586
- relaynode was removed in a56e853

This is a repeat of commit 3aa68cd397
which was lost in a rework of version.sh.
git worktrees have a .git file rather than a .git directory, so building
in a worktree caused version.sh to generate an error.
