Tweak engine startup, initial silence
...
This can help when running with very low latency and the
initial process callback is [indirectly] expensive.
E.g. load a heavy session the a RPi4, initial setup can pull
in a lot of data, which blocks the bus.
In particular with the ALSA backend this can lead to poll timeout
which effectively stops the backend.

ALSA: add locks to safely add/remove MIDI devices

Theoretically this could be lock-free by using a queue of device
ports to be added/remove in sync in the process-callback, but
realistically adding/removing devices doesn't have to be rt-safe.

Unfortunately it seems that in zita-alsa-pcmi doesn't set state() correctly in

first guess would be that set_hwpar is failing and state() is not
representative of the actual error.
