Remove ambiguous API implementation
...
* PortEngine::available() implementation
* AudioEngine::connected() wrapper
Eventually we may re-introduce PortEngine::available along
with a libardour internal port-engine.

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.

Abstract definition of rt-scheduler policy
...
pthread-w32 does not support pthread_setschedparam() with
SCHED_FIFO and bails out. While pthread_create() simply ignores the policy
and sets the priority regadless.
This only affects ctrl-surface event-loops & AutomationWatch on Windows.

being skipped because PortAudioBackend::available() still false
until the first callback.

Fix latency compensation for audio data in portaudio backend
...
For drivers that correctly report latency values(ASIO) this should result a
much closer alignment of audio in a loopback test. Measurement and
adjustment may still be needed, especially for non-ASIO drivers.
Testing with the RME HDSP Multiface and Yamaha AG06 using ASIO drivers results
in maximum offset of a couple of samples.

Use portaudio error codes in the PortaudioIO class.
...
Having error codes defined in PortaudioIO means it is not dependent on the
ErrorCodes in AudioBackend but it doesn't really make sense to have another
set, so just use the PA ones until they become insufficient.
