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

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

30b087ab3d globally change all use of "frame" to refer to audio into "sample".
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
and video in order to keep the legible

7258c6334d Namespace PBD::RingBuffer
class RingBuffer<> is a very generic name and should not pollute the
global namespace.

TODO find out how to make std::set::find() work with custom sort order,
as std::find may only be O(N) and not O(log (N)).

d1874d4685 optimize port lookup, adding/removing/reconnecting routes
xxxAudioBackend::connected_to() is called O(N^2) when building the graph.
Mitigate this by using an O(log(N)) lookup.

This duplicates the storage (both set and map and both are kept in sync.
Changing this to a boost:bidirectional might be nice, before updating
other backends.
