Extend a bit 'NO_MAIN'/'NO_USER_REFCOUNT'/etc. flags to ID allocation itself.

No real reason we keep this only to copying, creating ID outside of
database is handy as well!

Also, add helpers to add/remove an ID from Main, and to set/clear its
'user refcounting' status. Those will be useful in future complex ID
manipulation cases (like static override...).

Some cosmetic renaming.

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.
