ALSA backend: code cleanup and scoping and indent
...
This is combination of clang-format and manual edits.
The latter mainly to add braces and reduce scope of variables.

ALSA: allow to select different I/O devices
...
This adds a basic support to use multiple sound-cards, currently
limited to two devices: In/Out with shared settings.
Advanced setups still have to resort to using the ARDOUR_ALSA_EXT
environment variable

This is intended to prevent crashes when unregister_port() modifies the contents of these
two members at the same time that something else is iterating over them.

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.

and accumulated playback-latency for physical-inputs
after Ardour is done setting all non-physical port latencies.
