David Anderson 22507adf54 wgengine/magicsock: stop depending on UpdateDst in legacy codepaths.
This makes connectivity between ancient and new tailscale nodes slightly
worse in some cases, but only in cases where the ancient version would
likely have failed to get connectivity anyway.

Brad Fitzpatrick f85769b1ed wgengine/magicsock: drop netaddr.IPPort cache
netaddr.IP no longer allocates, so don't need a cache or all its associated
code/complexity.

This totally removes groupcache/lru from the deps.

Also go mod tidy.

Brad Fitzpatrick 5efb0a8bca cmd/tailscale: change formatting of "tailscale status"
* show DNS name over hostname, removing domain's common MagicDNS suffix.
  only show hostname if there's no DNS name.
  but still show shared devices' MagicDNS FQDN.

* remove nerdy low-level details by default: endpoints, DERP relay,
  public key.  They're available in JSON mode still for those who need
  them.

* only show endpoint or DERP relay when it's active with the goal of
  making debugging easier. (so it's easier for users to understand
  what's happening) The asterisks are gone.

* remove Tx/Rx numbers by default for idle peers; only show them when
  there's traffic.

* include peers' owner login names

* add CLI option to not show peers (matching --self=true, --peers= also
  defaults to true)

* sort by DNS/host name, not public key

* reorder columns

Josh Bleecher Snyder 56a7652dc9 wgkey: new package
This is a replacement for the key-related parts
of the wireguard-go wgcfg package.

This is almost a straight copy/paste from the wgcfg package.
I have slightly changed some of the exported functions and types
to avoid stutter, added and tweaked some comments,
and removed some now-unused code.

To avoid having wireguard-go depend on this new package,
wgcfg will keep its key types.

We translate into and out of those types at the last minute.
These few remaining uses will be eliminated alongside
the rest of the wgcfg package.

Christine Dodrill 7ea809897d ipn/ipnserver: enable systemd-notify support
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.

Josh Bleecher Snyder aa9d7f4665 tstime: add Parse3339B, for byte slices
Use go4.org/mem for memory safety.
A slight performance hit, but a huge performance win
for clients who start with a []byte.
The perf hit is due largely to the MapHash call, which adds ~25ns.
That is necessary to keep the fast path allocation-free.

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.

Brad Fitzpatrick 8b94a769be cmd/tailscaled: use the standard flag page instead of getopt
