0d668b9beb ALSA backend: always register ports with systemic latency

bf5864aaca Use PBD::to_string() from pbd/string_convert.h in JACK utils 
Use pbd/string_convert.h API instead of std::ostream for numeric formatting to
remain locale independent and not have to use a LocaleGuard.

6968c9f909 Drain ALSA raw-midi buffers after 64 bytes 
Very long sequence of *concurrent* events may otherwise be truncated
because the backend requests a buffer-size of 64 bytes via
snd_rawmidi_params_set_buffer_size().

f9db9bf5fd Retain order of concurrent MIDI events 
This fixes an issue with FaderPort8 (and maybe other surfaces or synths).

d10913e2de Fix intermittent hang when stopping PortaudioBackend 
This issue is not always reproducible but when it does occur it happens
somewhat consistently on both 32bit and 64bit builds(Tested on Windows 7).

The midiOutReset call does not return (or it takes so long that it might as
well be indefinite) and as it is not strictly necessary just remove it.

Resolves: http://tracker.ardour.org/view.php?id=7095

33e95a1577 rename Tempo _beats_per_minute to _note_types_per_minute, provide pulse helpers. 
- adds quarter_notes_per_minute(), note_divisions_per_minute (double)
	  pulses_per_minute() and frames_per_quarter_note()

	- this should be a no-op except for the use of tempo by
	  the vst callback which definitely uses quarter notes per minute.

	- the XML node for TempoSection named 'beats-per-minute'
	  has been renamed.

34c9ac9dd7 Tempo ramps - rename bbt_time() -> bbt_at_frame(), frame_time() -> frame_at_bbt() 2016-05-27 23:38:17 +10:00

7fc3b0c34c Initial stab at tempo ramps. 
Replaces the list of points in TempoMap with TempoSection functions, which
compute tempo-at or tick-at time relative to tempo section start.
TempoMap consults them additively to determine things like bbt_time(),
frame_time() get_grid() etc.
This has a marked effect on scrolling speed along with the code simplification
in the places it has been attempted.

Several things are broken here.
Currently every ramp except the last one is an exponential ramp. this may
be simple to fix :).
Mouse-over midi grid doesn't match mouse click grid. should also be simple.

Many things seem to work, but their accuracy should be in question until
each area has been addressed.

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.
