0be475ba46 Revert "tailcfg, controlclient, magicsock: request IPv6 endpoints, but ignore them"
Breaks something deep in wireguard or magicsock's brainstem, no packets at all
can flow. All received packets fail decryption with "invalid mac1".

This reverts commit 94024355ed.

12a6626a94 tsweb: use a ResponseWriter wrapper to log more accurately.
Also adds tests, because the logging handler is acquiring a fair
number of branches.

6ddbcab71e logtail: rename the unused CheckLogs to DrainLogs
Its semantics has changed slightly, this will let us use it to
drive batched logging in special circumstances.

a184e05290 wgengine/magicsock: listen on udp6, use it for STUN, report endpoint
More steps towards IPv6 transport.

We now send it to tailcontrol, which ignores it.

But it doesn't actually actually support IPv6 yet (outside of STUN).

addbdce296 wgengine, ipn: include number of active DERPs in status
Use this when making the ipn state transition from Starting to
Running. This way a network of quiet nodes with no active
handshaking will still transition to Active.

1ad78ce698 magicsock: reconnect to home DERP on key change
Typically the home DERP server is found and set on startup before
magicsock's SetPrivateKey can be called, so no DERP connection is
established. Make sure one is by kicking the home DERP tires in
SetPrivateKey.

455ba751d9 magicsock: start connection to HOME derp immediately
The code as written intended to do this, but it repeated the
comparison of derpNum and c.myDerp after c.myDerp had been
updated, so it never executed.

120273d7f6 portlist: document, clean up, fix an open fd spike, optimize a bit
I noticed portlist when looking at some profiles and hadn't looked at
the code much before. This is a first pass over it. It allocates a
fair bit. More love remains, but this does a bit:
