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.

Explicitly use OSX

Previously this was inherited via PBD.
On MacOS/X, this adds
"-undefined dynamic_lookup -flat_namespace"
and various "-framework .." options to linkflags
Without this flag, .dylibs fail to link usually because
of missing `-lintl` (Undefined symbols: "_libintl_dgettext")
On other systems this is a NO-OP:
CFLAGS_OSX, CXXFLAGS_OSX and LINKFLAGS_OSX
are only set on the darwin platform.

NO-OP: fix some Wimplicit-fallthrough

gcc can recognize various regexps in comments. Since C++17 provides
