Alembic tests: make failures a bit easier to diagnose.

Fix T51762: Unit test script_alembic_import is failing.

Implemented workaround for use with the legacy depsgraph.

Fixed bl_load_py_modules / script_load_modules unit test

It tried to assert that
addons/io_blend_utils/blender_bam-unpacked.whl/__init__.py was loaded when
the io_blend_utils module was imported. However, this happens only on
demand, and not directly when importing the add-on.

Use for/else instead of setting 'ok' variable.

This is more efficient, and this use case is exactly what the else clause
is for.

Removed trailing spaces

Fix (unreported) missing Image usercount increase when copying UVProject modifier.

Fix (unreported) bad copying code of Surface Deform modifier.

Fix compiler warnings from own recent rB0d5c7e5e36b9.

Fix (unreported) bad copying of Ocean modifier.

Was needlessly complicated code, forgot to copy a value (foam_fade), and
was utterly leaking memory!

Fix (unreported) bad copying code in Mesh Deform modifier.

Fix (unreported) Dynamic Paint modifier not increasing ID usercount in copy function.

*Sigh* One more example of why we should keep ID management handling in
as few places as possible! It's impossible to keep more than a few
places in sync regarding which ID pointer is refcounted etc.

Fix (unreported) memory leak in Fluid modifier copying.

Also generally simplify/sanitize this copy code.

WIP

Cleanup: doxygen comments

Also remove duplicate & mismatching comments from grease-pencil header.
Keep comments close to implementation to avoid getting out of sync.

Fix T51774: Children particles hair interpolation not correct with textures or dp.

Children where always getting at least one segment of fixed length...

Now fully hidden ones (zero length) get no segment at all.

Note that even very short ones keep getting one 'unit' length segment - would
rather avoid changing that at this point, given how complex children
particles 'length' can get with all kind of modifiers... Think we can
live with that for now anyway.

Fix T51840: UI redraw in node editor header missing on pointcache bake

Missing a notifier handler in the node editor

Fix unreported: Copy-pasting nodes crashes when they have an undefined type

Docs: Fix file:line links in generated API docs

Add Cone: tip soft-min should be zero

Default value should be included in range.

Guarded allocator: Fix type in macro definition

The crash did not happen yet because we always had proper vmemh defined in
the parent scope.

Patch by Ivan Ivanov (aka obiwanus), thanks!
