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 backend: try to recover from poll errors
...
When recover() successfully re-initializes the device,
processing can continue just like after an x-run.
This can happen during initial session load of "expensive"
sessions (in particular on slow systems, e.g. Raspberry Pi)
usually with synths. Worker thread pulls in many external
files in the background which blocks the bus for a long time.
resulting in a poll-timeout.

Use PBD::to_string() from pbd/string_convert.h in JACK utils
...
Use pbd/string_convert.h API instead of std::ostream for numeric formatting to
remain locale independent and not have to use a LocaleGuard.

Drain ALSA raw-midi buffers after 64 bytes
...
Very long sequence of *concurrent* events may otherwise be truncated
because the backend requests a buffer-size of 64 bytes via
snd_rawmidi_params_set_buffer_size().

Fix intermittent hang when stopping PortaudioBackend
...
This issue is not always reproducible but when it does occur it happens
somewhat consistently on both 32bit and 64bit builds(Tested on Windows 7).
The midiOutReset call does not return (or it takes so long that it might as
well be indefinite) and as it is not strictly necessary just remove it.

rename Tempo _beats_per_minute to _note_types_per_minute, provide pulse helpers.
...
- adds quarter_notes_per_minute(), note_divisions_per_minute (double)
pulses_per_minute() and frames_per_quarter_note()
- this should be a no-op except for the use of tempo by
the vst callback which definitely uses quarter notes per minute.
- the XML node for TempoSection named 'beats-per-minute'
has been renamed.
