Do not try to close xmon fd if we don't have one
...
Also, ignore errors if we can't close it. Fixes #134 .

Wait forever, rather than having timeouts
...
The goal here is to not have constant wakeups due to timeout. Do
not attempt to clean things up nicely before termination -- just
terminate instead. We can setup a proper termination system in
the future, I first want to see if this makes a difference.
Also, change xmon to use pipes for communication, so that it can
wait without timers as well.
Also, `write` directly for logging, so that we know the logs will
make it to the file after the logging call returns (since we now
do not have the chance to flush them afterwards).

Rate limit binnable xmon requests
...
This involved clearly separating non-clearable and clearable alerts,
which simplifies the design and I think satisfies all our needs.

Use homegrown Xmon
...
I got annoyed at the old lib dropping requests when queue gets
full, I could probably fix but this is almost certainly quicker.

Do not re-insert requests in C++ xmon code

It could mess up the ordering.

Never die because of bad Xmon
...
It will alert if we're disconnected anyway, and when restarting
everything this causes crashes.

Actually wait for things to finish terminating before reaping next one
...
Fixes #27 . This is all kind of clunky right now, it would be much
better to just standardize the `run()` function pattern.
