Fix stupid mistake in new LineStyle copying code.

Fix several crashes and other issues in new ID copying code.

Mostly in core and animdata area. Code should now also be more robust,
and slightly simpler & cleaner.

Huuuuge refactor of Scene copying, added to generic library ID copying.

Note: there are several known issues with this commit (and most likely
more unknown ones), to be fixed in next ones.

Add VFont copying.

Not much happy, have to include BKE_curve in BLI_freetypefont to copy
nurbs... Not sure why fonts are in BLI tbh. We are already replicating
quite a bit of nurbs logic there. :(

Add Sound copying callback.

Move Palette, PaintCurve and CacheFIle to new ID copying system.

Move Mask and FreestyleLineStyle to new ID copying code.

Move Text, Brush and GPencil datablocks to new copying code.

Move Action to new copying code.

Move Group and ParticleSettings to new copying system.

Also fix several mistakes from previous commits.

Move World and MovieClip to new copying system.

Rename new `BKE_<foo>_copy_ex` to `BKE_<foo>_copy_data`.

Those are not actually copying the ID, only its internal subdata (and
other ID-specific handling). Generic processing common to all ID copying
is done by `BKE_id_copy_ex()`!

Move Material, Texture and Image datablocks to new copying code.

Note that this is also bringing back Image copying code into 'regular'
process, instead of doing its own dirty cooking.
