Dummy backend: add realtime option
On windows this is still limited by the timer resolution, but
it's a start. This is mainly intended to be used with NDI or
other external sources without actual audio hardware.

b35518e212 switch from boost::{shared,weak}_ptr to std::{shared,weak}_ptr
This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.

39ed528e25 std-ize: convert all boost shared/weak ptr includes to <memory>
Also fix stdint.h -> cstdint and alphabetically order std includes

b9cb306e8b use shared_ptr to manage backend port lifetimes (Pulse,ALSA,Dummy,JACK)
JACK is not yet finished.

Changes also include minor reformatting and a spelling correction (latecies to latencies)

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

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

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.
