f5c52f500a 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.

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

355183f1ab partially revert some of the recent work on tempo to reflect new understanding of the problem. behaviour is now believed to be totally correct but awaiting a bit more testing

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.
