Josh Bleecher Snyder 8fb66e20a4 wgengine/magicsock: remove DefaultPort const
Assume it'll stay at 0 forever, so hard-code it
and delete code conditional on it being non-0.

Brad Fitzpatrick f99e63bb17 ipn: don't Logout when Windows GUI disconnects
Logout used to be a no-op, so the ipnserver previously synthensized a Logout
on disconnect. Now that Logout actually invalidates the node key that was
forcing all GUI closes to log people out.

Instead, add a method to LocalBackend to specifically mean "the
Windows GUI closed, please forget all the state".

Fixes tailscale/corp#1591 (ignoring the notification issues, tracked elsewhere)

David Anderson bc4381447f net/tstun: return the real interface name at device creation.
This is usually the same as the requested interface, but on some
unixes can vary based on device number allocation, and on Windows
it's the GUID instead of the pretty name, since everything relating
to configuration wants the GUID.

Brad Fitzpatrick 39b9ab3522 cmd/tailscaled: rename isUserspace to useNetstack
The bool was already called useNetstack at the caller.
isUserspace (to mean netstack) is confusing next to wgengine.NewUserspaceEngine, as that's
a different type of 'userspace'.

Part of overall effort to clean up, unify, use link monitoring more,
and make Tailscale quieter when all networks are down. This is especially
bad on macOS where we can get killed for not being polite it seems.
(But we should be polite in any case)

Brad Fitzpatrick 57dd247376 cmd/tailscaled, logpolicy, logtail: support log levels
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.

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 86c271caba types/logger: move RusagePrefixLog to logger package, disable by default
The RusagePrefixLog is rarely useful, hasn't been useful in a long
time, is rarely the measurement we need, and is pretty spammy (and
syscall-heavy). Disable it by default. We can enable it when we're
debugging memory.

Brad Fitzpatrick 8b94a769be cmd/tailscaled: use the standard flag page instead of getopt
Per discussion with @crawshaw. The CLI tool already used std flag anyway.
If either of them, it would've made more sense for the CLI to use getopt.
