Change from a single-case type switch to a type assertion
with an early return.
That exposes that the name arg to gen is unneeded.

Spelling out the command to run for every type
means that changing the command makes for a large, repetitive diff.
Stop doing that.

Real goal is to eliminate some allocs in the STUN path, but that requires

The earlier 382b349c54 was too late,

Add a mode control for derp server, and add a "manual" mode
to get derp server certificate. Under manual mode, certificate
is searched in the directory given by "--cert-dir". Certificate
should in PEM format, and use "hostname.{key,crt}" as filename.
If no hostname is used, search by the hostname given for listen.

* types/key: add ControlPrivate, with custom serialization.
ControlPrivate is just a MachinePrivate that serializes differently
in JSON, to be compatible with how the Tailscale control plane
historically serialized its private key.

cmd/derper: listen on host of flag server addr for port 80 and 3478
When using custom derp on the server with multiple IP addresses,
we would like to bind derp 80, 443 and stun 3478 to a certain IP.
derp command provides flag `-a` to customize which address to bind
for port 443. But port :80 and :3478 were hard-coded.

rsc.io/goversion is really expensive.
Running version.ReadExe on tailscaled on darwin
allocates 47k objects, almost 11mb.
All we want is the module info. For that, all we need to do
is scan through the binary looking for the magic start/end strings
and then grab the bytes in between them.
We can do that easily and quickly with nothing but a 64k buffer.
