Make click & drag in the left-hand half of a region with the Timestretch
tool stretch the region on its left, leaving the end position of the new
time-stretched region in the same place as the end of the original.
This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
The design ignored the ratio computed by the drag interaction, and relied on getting the stretch
ratio from the dialog. This truncated the actual ratio, leading to (relatively) small errors
in the length of the generated region.
Now, if the ratio provided by the drag is not (1/1) (i.e. a single click while in timefx mode)
then the percentage stretch spinner is marked insensitive and the stretch ratio is taken from
the given ratio. For single clicks, the user can still adjust the percentage as they wish

Previously, when running timefx on multiple regions on
the same track, undo commands accumulated for each region
in the playlist. Resulting in duplicate actions on undo/redo.
```

git history begins in 2005. So (C) from 1998..2005 is lost. Also some
(C) assignment of commits where the committer didn't use --author.
When processing multiple regions, apply results at the end, so that
when the action is canceled, no changes are applied.
Furthermore, do not commit an undo-command if time-stretch is a no-op.
OptionPitchHighQuality - Use the highest quality
method for pitch shifting. This method has a CPU cost
approximately proportional to the required frequency shift
This fixes an issue with pitch-shift using the most recently used
time-stretch algorithm, which may be "resample.." (effective NO-OP).
Also leave a ToDo note regarding rubberband crispness levels for later.
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
- also allow moving of automation lines in internal mouse mode.
- this is also a first pass at ensuring that if an operation does
nothing, avoid an undo entry.
It's slightly possible that this causes trivial build failures on different
configurations, but otherwise shouldn't cause any problems (i.e. no actual
changes other than include/naming/namespace stuff). I deliberately avoided
removing libardour-config.h since this can mysteriously break things, though a
few of those do seem to be unnecessary.
This commit only targets includes of ardour/*.h. There is also a very large
number of unnecessary includes of stuff in gtk2_ardour; tackling that should
also give a big improvement in build time when things are modified.
