... To append files during recording or import, it doesn't depend on the
subclasses of BlockFile, instead taking a factory function to which it gives
the filename; and the choice of factory function is also lifted up through the
level of class Sequence which is just above DirManager.
This frees four files from dependency cycles, including DirManager.cpp but not
yet Sequence.cpp
... Unnecessary because transitively included.
But each .cpp file still includes its own .h file near the top to ensure
that it compiles indenendently, even if it is reincluded transitively later.
... except Audacity.h; and in no others.
Do so even if Experimental.h gets multiply included, as in both the .h and
.cpp files.
This makes it easier to do a text scan to be sure there are no unintended quiet
changes of meaning because of omission of Experimental.h when the flag is
an enabled one.
Also move inclusions of Experimental.h earlier.
Also don't require Experimental.h to be preceded by Audacity.h to define
EXPERIMENTAL_MIDI_OUT correctly.
... for wxString and wxArrayStringEx, holding file paths (absolute or relative,
directory or plain file); to be replaced later with different types
(not yet using std::vector, becase of some uses of wxArrayString::Index with
two arguments)
... Assuming that large unsigned magnitudes with high order bit set are not
the problem, but signed negatives of small magnitude may be:
1) Always cast the unsigned to signed in comparisons, not the other way.
Also:
2) Cast unsigned TERM to signed by itself, before subtracting. Don't cast
the result.
3) Rewrite some comparisons by moving subtracted term to other side.

- Dead code from experiments in SelectionBar removed.
- Many warnings about unused parameters fixed with WXUNUSED()
- Many warnings about signed / unsigned comparisons cleaned up.
- Several 'local variable declared but not used' warnings fixed.
These basics add a colour index to each clip and track, and allow for a choice of four colours to be set from the track menu drop down. The additional wave colours (red, green and black) are not currently configurable, and the colour index is not currently saved.
... Simplify. Don't assume e->mOffset is zero. Check consistency afterward.
Do not leave responsibility for simplification of discontinuities to higher
level code.
Allow real discontinuities at the end of the insertion; no more readjustment of
times of points.
Changed the criterion for deciding when two clips are immediately next to each other, and made it into a function: WaveClip::SharesBoundaryWithNextClip.
... Formerly this was done correctly only for cut and delete from WaveTrack,
paste into WaveTrack, and sync-lock adjustment of WaveTrack (either lengthening
or shortening).
Now also properly done for TimeTrack cut and paste, and also for:
Split cut
Split delete
Trim
... in WaveClip and WaveTrack, to save as much recording as we can,
assuming the strong guarantees that Sequence will give.
Also comment that some other WaveTrack methods can give strong guarantee,
incidentally to making HandleClear give strong.
