3606e68721 net/interfaces: fix default route lookup on Windows
It wasn't using the right metric. Apparently you're supposed to sum the route
metric and interface metric. Whoops.

While here, optimize a few little things too, not that this code
should be too hot.

Fixes #2707 (at least; probably dups but I'm failing to find)

f35b8c3ead derp: fix meshing accounting edge case bug
If a peer is connected to multiple nodes in a region (so
multiForwarder is in use) and then a node restarts and re-sends all
its additions, this bug about whether an element is in the
multiForwarder could cause a one-time flip in the which peer node we
forward to.  Note a huge deal, but not written as intended.

Thanks to @lewgun for the bug report in #2141.

1dd2552032 wgengine: actively log FlushDNS.
Intended to help in resolving customer issue with
DNS caching.

We currently exec `ipconfig /flushdns` from two
places:
- SetDNS(), which logs before invoking
- here in router_windows, which doesn't

We'd like to see a positive indication in logs that flushdns
is being run.

As this log is expected to be spammy, it is proposed to
leave this in just long enough to do an unstable 1.13.x build
and then revert it. They won't run an unsigned image that
I build.

adf696172d wgengine/userspace: reduce allocations in getStatus
Two optimizations.

Use values instead of pointers.
We were using pointers to make track the "peer in progress" easier.
It's not too hard to do it manually, though.

Make two passes through the data, so that we can size our
return value accurately from the beginning.
This is cheap enough compared to the allocation,
which grows linearly in the number of peers,
that it is worth doing.

278e7de9c9 logtail: always send a json array
The code goes to some effort to send a single JSON object
when there's only a single line and a JSON array when there
are multiple lines.

It makes the code more complex and more expensive;
when we add a second line, we have to use a second buffer
to duplicate the first one after adding a leading square brackets.

The savings come to two bytes. Instead, always send an array.

93284209bc logtail/filch: preallocate a scanner buffer
Scanning log lines is a frequent source of allocations.
Pre-allocate a re-usable buffer.

This still doesn't help when there are giant log lines.
Those will still be problematic from an iOS memory perspective.
For more on that, see https://github.com/tailscale/corp/issues/2423.

(For those who cannot follow that link, it is a discussion
of particular problematic types of log lines for
particular categories of customers. The "categories of customers"
part is the reason that it is a private issue.)

There is also a latent bug here. If we ever encounter
a log line longer than bufio.MaxScanTokenSize,
then bufio.Scan will return an error,
and we'll truncate the file and discard the rest of the log.
That's not good, but bufio.MaxScanTokenSize is really big,
so it probably doesn't matter much in practice now.
Unfortunately, it does prevent us from easily capping the potential
memory usage here, on pain of losing log entries.
