Using the new publish/discovery stuff from the past couple of commits,
if we can find a matching socket path for a running gui, and the
configuration is likely a match, then use the mux protocol to talk
to the already running gui and ask it to spawn the equivalent program
into the same process.

This was broken by the changes in
aad493ab2a. The issue was that the
channel send didn't wakeup the receiver. I'm not sure why, and I tried
a couple of different async channel implementation.
Doing the simplistic solution here works reliably.
kindof a lot going on in this commit, unintentionally:
* Need the lua context set to be moved into the config crate
otherwise configs cannot be parsed by the server and we end
up with the default configs
* Make the server use smol for async io
* Drop the use of the daemonize crate, which I had forked anyway.
Just inline our own tighter daemonize module
* Improve daemon spawning synchronization, however, it still needs
work for windows to avoid blocking forever where we don't do
daemonizing.
The future won't ever complete if you don't connect the waker
from the context!
Prove this out by making the windowops functions async and
verifying them in the async example
