This saves a layer of translation, and saves us having to
pass in extra bits and pieces of the netmap and prefs to
wgengine. Now it gets one Wireguard config, and one OS
network stack config.

For "tailscale status" on macOS (from separately downloaded
cmd/tailscale binary against App Store IPNExtension).
(This isn't all of it, but I've had this sitting around uncommitted.)
Implement rate limiting on log messages
Addresses issue #317, where logs can get spammed with the same message
nonstop. Created a rate limiting closure on logging functions, which
limits the number of messages being logged per second based on format
string. To keep memory usage as constant as possible, the previous cache
purging at periodic time intervals has been replaced by an LRU that
discards the oldest string when the capacity of the cache is reached.

These will be used for dynamically changing the identity of a node, so
its ACL rights can be different from your own.
Note: Not all implemented yet on the server side, but we need this so
we can request the tagged rights in the first place.

We were printing "Shields Up" when the netmap wasn't initialized yet,
which while technically effectively true, turned out to be confusing
when trying to debug things.

When shields are up, no services are available to connect to, so hide
them all. This will also help them disappear from the UI menu on
other nodes.

This sets a default packet filter that blocks all incoming requests,
giving end users more control over who can get into their machine, even
if the admin hasn't set any central ACLs.

- Reset() was not including a Version field, so was getting rejected;
the Logout operation no longer happened when the client got disconnected.
- Don't crash if we can't decode 0-byte messages, which I suspect might
sometimes come through on EOF.

The tests cheat at filling out web forms by directly POSTing to
the target. The target for authURLs has changed slightly, the base
authURL now redirects the user to the login page.
Additionally, the authURL cycle now checks the cookie is set
correctly, so we add cookie jars where necessary to pass the
cookie through.
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.

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)

This removes the need for go-cmp, which is extremely bloaty so we had
to leave it out of iOS. As a result, we had also left it out of macOS,
and so we didn't print netmap diffs at all on darwin-based platforms.
Oops.
As a bonus, the output format of the new function is way better.
Minor oddity: because I used the dumbest possible diff algorithm, the
sort order is a bit dumb. We print all "removed" lines and then print
all "added" lines, rather than doing the usual diff-like thing of
interspersing them. This probably doesn't matter (maybe it's an
improvement).
We weren't setting UsePacketFilter, so the synthetic ping packets
used to establish a connection were never being sent.

* adds new packet "netcheck" to do the checking of UDP, IPv6, and
nearest DERP server, and the Report type for all that (and more
in the future, probably pulling in danderson's natprobe)
* new tailcfg.NetInfo type
* cmd/tailscale netcheck subcommand (tentative name, likely to
change/move) to print out the netcheck.Report.

On unix, we want to provide a full path to the desired unix socket.
On windows, currently we want to provide a TCP port, but someday
we'll also provide a "path-ish" object for a named pipe.
For now, simplify the API down to exactly a path and a TCP port.

This is a prelude to supporting relaynode's --routes in
tailscaled. The daemon needs to remembers routes to
advertise, and the CLI needs to be able to change the
set of advertised routes. Prefs is the thing used for
both of these.

This is a prelude to making it truly optional, once state

- It was only used in one currently-unused client.
- It's an imperative command, not a configuration setting.
- The LoginFlags stuff in controlclient feels like it needs
a refactor anyway.
I'll put this logic back once ipnd owns its state and Backend
commands reflect that.

The linter is strictly correct, but the code is structured
this way to avoid variable shadowing problems in the following
for loop. The context doesn't leak.
Staticcheck is correctly pointing out that this code is hard to
follow. However, this chunk of code is in service of enforcing
one frontend <> one backend, and we want to remove that limitation.
So, we'll just ignore the lint warning until this entire piece of
code goes away.
