7744037c86 Timecode: fix subframe rounding 
if sub-frames are used, frames are rounded up for the later half of
a sub-frame.  e.g. @48KSPS, 25fps, 100 subframes per frame
audio-samples >=1910 already yield 00:00:00:01

e1581242ca implement TC offset for slave&generator. 
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

b8ff65ea1b overhaul timecode calculations 
in particular proper SMPTE12M drop-frame support
and subframe rounding.

5eeefbb3a5 Don't notify user if fps changes only affect speed but not counting. 
also unify labels for 29..97XX and simplify fps display.

8c9c0836a3 experimental option to support LTC 29.97000 fps generators. 
also change 29.97ndf frame-rate to 30000/1001.

a9abe3b1e1 move TimecodeFormat to libtimecode 
provide a way to convert any TimecodeFormat to float frame-rate,
not only the currently active timecode_foramt.

e9b4f14668 rename Timecode::BBT_Time::ticks_per_beat to Timecode::BBT_Time::ticks_per_bar_division which is a more accurate and informative name. The number doesn't describe the smallest division of a "beat" (which is only defined contextually anyway), but rather the smallest division of the the divisions of a bar. If using a meter of 4/8, there are 4 divisions per bar, and we can divide each one into ticks_per_bar_division pieces; in a separate meter (section) of 3/8, there are 3 divisions per bar, each of which can be divided into ticks_per_bar_division_pieces.
