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

David Crawshaw 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.

Brad Fitzpatrick 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).

David Crawshaw 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.

David Crawshaw 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.

David Crawshaw 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.

David Anderson 98eceae55e tsweb: add a Handler type.
Handler is like http.Handler, but returns errors. ErrHandler
converts back to an http.Handler, with added error handling

Brad Fitzpatrick 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:

name       old time/op    new time/op    delta
GetList-8    9.92ms ± 8%    9.64ms ±12%     ~     (p=0.247 n=10+10)

name       old alloc/op   new alloc/op   delta
GetList-8     931kB ± 0%     869kB ± 0%   -6.70%  (p=0.000 n=10+10)

name       old allocs/op  new allocs/op  delta
GetList-8     4.59k ± 0%     3.69k ± 1%  -19.71%  (p=0.000 n=10+10)

Brad Fitzpatrick db2436c7ff wgengine/magicsock: don't interrupt endpoint updates, merge all mutex into one
Before, endpoint updates were constantly being interrupted and resumed
on Linux due to tons of LinkChange messages from over-zealous Linux
netlink messages (from router_linux.go)

Now that endpoint updates are fast and bounded in time anyway, just
let them run to completion, but note that another needs to be
scheduled after.

Now logs went from pages of noise to just:

root@taildoc:~# grep -i -E 'stun|endpoint update' log
2020/03/13 08:51:29 magicsock.Conn: starting endpoint update (initial)
2020/03/13 08:51:30 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor")
2020/03/13 08:51:31 magicsock.Conn: starting endpoint update (link-change-minor)
2020/03/13 08:51:31 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor")
2020/03/13 08:51:33 magicsock.Conn: starting endpoint update (link-change-minor)
2020/03/13 08:51:33 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor")
2020/03/13 08:51:35 magicsock.Conn: starting endpoint update (link-change-minor)
2020/03/13 08:51:35 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor")

Or, seen in another run:

2020/03/13 08:45:41 magicsock.Conn: starting endpoint update (periodic)
2020/03/13 08:46:09 magicsock.Conn: starting endpoint update (periodic)
2020/03/13 08:46:21 magicsock.Conn: starting endpoint update (link-change-major)
2020/03/13 08:46:37 magicsock.Conn: starting endpoint update (periodic)
2020/03/13 08:47:05 magicsock.Conn: starting endpoint update (periodic)
