Paul Davis was responsible for introducing almost all of this.

The general design here is wrong, because it should be more general and cover all possible sync sources.
But it does work, it is used in Tracks, and my attempt to do it correctly revealed the problem to be
an EXTREMELY difficult design issue (as in: two weeks of work on it did not really solve the
fundamental issues with slave design).
So, here it is for now, c/o Grygorii

incoming MIDI data has to be parsed EVERY process cycle, not just when Slave::speed_and_position() is called.
The private MIDI::Parser owned by the MTC and MClck slaves was irrelevant, since the port has its own.
See comments in midi_port.h on the strangled inheritance heirarchy.

e.g. 44.1k [SPS] / 30 [fps] / 4 [MTC-frames per timecode-frame] = 367.5 [samples per MTC-frame]

There is no actual use-case to set it to anything else than 100.
timecode subframes are only used for ruler marks and the snap to grid.
libtimecode is still /aware/ of the subframe setting.

Many related changes that require atomic update, mostly
because ClockOption slots changed:
* change offset config format to std:string (backwards compat - reads 0)
* make Timecode offset independent from fps
* sample_to_timecode() handle negative sample-num
* audio-clock fix entry and edit of negative numbers
* option editor:
- remove old global internal offset
- add slave & generator TC entry
- still needs UI cleanup, tooltops, maybe sep. tab..
* LTC & MTC slave& generator:
- cache offset
- subscribe to parameter changes

So far only LTC slave, LTC generator and MTC slave.
MTC generator remains to be done.

Close loop of quarter-frame DLL and
also re-enable the deadzone around speed 1.0.
DLL bandwidth have been slightly adjusted empirically.

trade-off constant re-sampling to achieve sample-delta ~0,
with trying to avoid resampling if the delta is within
1% of the sample-rate.

negative delta: Ardour is behind,
positive delta: Ardour is ahead of ext clock.

MIDI only specifies the frame-count, not the rate.
in the vast majority of cases MIDI's
"Count to 30 use drop-frame" is 29.97df fps.
