Message:

First go at sigwait-based signal handling

Instead of relying on pselect and signal masking to listen for signals,
which glib doesn't support, we spawn a dedicated signal thread that
loops in sigwait. These signals are posted back to the main message loop
which may handle them at will. This avoids the need for complex
reentrant code and sig_atomic_t.

This removes the final pre-select action.

SIGINT doesn't quite work right yet because we can no longer take it in
the middle of an event loop iteration.
