RT-safe jack transport time-master
Prefer a try-lock, instead of locking the tempo-map.

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

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.

4dc63966f0 globally remove all trailing whitespace from ardour code base.
Paul Davis was responsible for introducing almost all of this.
