Patch implements better way to control playback speed than it is
possible to do with speed effect. Speed factor property can be set in
Time panel.
There are 2 layers of control:
Option to retime movie to match scene FPS rate.
Custom speed factor to control playback rate.
Since playback rate is strip property, it is now possible to manipulate
strip as normal one even if it is retimed.
To facilitate manipulation, some functions need to consider speed factor
and apply necessary corrections to strip offset or strip start. These
corrections may need to be float numbers, so start and offsets must be
float as well.
Sound strips now use speed factor instead of pitch. This means, that
strips will change length to match usable length. In addition, it is
possible to group movie and sound strip and change speed of meta strip.
Use a shorter/simpler license convention, stops the header taking so
much space.

Ref D14069
2 factor variables were passed to effects, but they were hard coded to
have same value.
Remove duplicate variable from arguments, rename single argument to
`fac`. Inverted factor variables were renamed to `mfac`. Any other
factor related variables are prefixed with `temp_`.
There should be no functional changes.
**Changes:**
- New enums correspond to 4 modes: `Stretch`, `Multiply`, `Frame Number` and `Length`.
- "`Multiply Factor`" has been removed;
- Value corresponding to "`use as speed`" enabled is now the value appended to the `Multiply` enum;
- Value corresponding to "`use as speed`" disabled is now the value appended to the `Frame Number` enum;
- Value corresponding to "`Scale to Length`" enabled is now the value appended to the `Length` enum;
- Except `Stretch` each mode has now its respective control values.
