55095df644 net/interfaces: get Linux default route from netlink as fallback
If it's in a non-standard table, as it is on Unifi UDM Pro, apparently.

5d085a6f41 controlhttp: add some docs, change Dial's path from /switch to /ts2021
When I deployed server-side changes, I put the upgrade handler at /ts2021
instead of /switch. We could move the server to /switch, but ts2021 seems
more specific and better, but I don't feel strongly.

Turns out we're pretty good already at init-time work in tailscaled.
The regexp/syntax shows up but it's hard to get rid of that; zstd even

bb94561c96 net/netutil: fix regression where peerapi would get closed after 1st req
I introduced a bug in 8fe503057d when unifying oneConnListener
implementations.

The NewOneConnListenerFrom API was easy to misuse (its Close method
closes the underlying Listener), and we did (via http.Serve, which
closes the listener after use, which meant we were close the peerapi's
listener, even though we only wanted its Addr)

Instead, combine those two constructors into one and pass in the Addr
explicitly, without delegating through to any Listener.

e31d68d64e hostinfo: use the sentinel value set by the MSI installer to detect MSI package type
The MSI installer sets a special sentinel value that we can use to detect it.

I also removed the code that bails out when the installation path is not
`Program Files`, as both the NSIS and MSI installers permit the user to install
to a different path.
