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.

Dummy: Engine-Pulse audio/midi generators 
This produces synchronous events on Audio and MIDI ports.
One rvent per second, exactly at every second since engine-start.

MIDI: C-4 Note-on/off (1 sample long)
Audio: +1/-1 transition:
       +1 in sync with Note-on,
       -1 in sync with Note-off

NO-OP: fix some Wimplicit-fallthrough 
gcc can recognize various regexps in comments. Since C++17 provides
[[fallthrough]], using /* fallthrough */ consistently seems
appropriate until we switch to C++17.

Prefix all env variable with "ARDOUR_" 
In particular "CONCURRENCY" can be problematic. But in general
it's good practice to use a namespace prefix for app-specifics.

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.

Remove ambiguous API implementation 
* PortEngine::available() implementation
* AudioEngine::connected() wrapper

Eventually we may re-introduce PortEngine::available along
with a libardour internal port-engine.
