8bb91099c5 wscript: drop configure statements already present in the top level wscript
Avoid repeated pointless configure messages like:
Checking for 'g++' (C++ compiler!)                   : /usr/lib64/ccache/g++
Checking for 'gcc' (C compiler)                      : /usr/lib64/ccache/gcc

Prevent deadlock when disconnecting
The backend holds `_port_callback_mutex` while disconnecting ports.
In some cases disconnecting a port can drop the last reference
resulting in a port-deletion from the connection handler.
This in turn will eventually aquire the `_port_callback_mutex`
and deadlock.

This is now circumvented by using atomic operations instead of
taking a lock to set the `_port_change_flag`.

The flag is also used to trigger a latency update in some cases,
atomic is preferable to taking a lock to set this flag.

Separate user-set pretty-names from hardware I/O names
This allow to restore original engine port-names as set
by the backend. ALSA MIDI, CoreAudio, CoreMIDI and PortAudio
drivers can provide human readable physical port names for
some devices.

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.

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

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

37df98d0af CoreAudio/MIDI: add locks for port-registration
CoreMIDI ports are dynamic. When dis/connecting a device CoreAudio's
AudioHardware-PropertyListener triggers a callback which can
add/remove ports.

This can not happen concurrently with processing, but it may happen
concurrently with a user creating tracks using Ardour's UI
and/or session-load/setup.

ab3889fff8 Propagate Latency to backend/system ports
Set accumulated capture-latency for physical-outputs
and accumulated playback-latency for physical-inputs
after Ardour is done setting all non-physical port latencies.

This will be needed for latency-compensation of the complete graph.

467c801ce8 Abstract definition of rt-scheduler policy
pthread-w32 does not support pthread_setschedparam() with

and sets the priority regadless.

This only affects ctrl-surface event-loops & AutomationWatch on Windows.
