support for subframe animation evaluation for masks.

fix for own bug - evaluating past the last frame of a mask didnt work at all.

* Added OpenCL kernel for bokeh blur
* Uncomment COM_OPENCL_ENABLED from COM_defines.h to test

Another fix for #31743: check for DM's verts number matches passed number of vertices

Now bevelled splines shall work in the same way as meshes.

Fix #31748: Blender crashes when typing "al" after opening spacebar menu.

Crash was introduced by own refactoring of poll functions in clip editor.

Fix #31743: Applying Smooth modifier to a curve crashes Blender

Actually there were two different issues involved here:

- Recently enabled Smooth modifier wasn't actually designed for curves, so
it in fact requires a bit bigger work to make it working.

For now added check for object's typy in this modifier and if it's not
mesh, it wouldn't try to use edges.

The reason why it worked in 3d viewport is that creating DM from curve while
displist is still ocntrcuting for would result in empty CDDM and that leads to
not taking edges into account, only vertexCos passed to modifier would be used.

This makes it behaving a bit differently from if it was a mesh, but still gives
quite reasonable result. Would leave actual fix for a guy who enabled smooth
modifier.

- Another issue is related on ensuring sculpt mask layer after applying modifier.
This shall happen only for meshes.

Clip editor: cleanup up header

One side of change is related on making code easier to follow, due it started
being quite messy because of all in-lined mode/view checks. Now there's a bit
of code duplication, but it's much easier to see what's going on there.

Another side of patch is related on re-arranging elements in header in a way
that follows rule "depending elements are placed after elements they depends on".
This might be a bit against mostly-used-based elements placement, but now it's
much easier to figure out where to add new option. Also it fits better other
blender's areas such as image editor header, i.e.

Mask editing: remove use_parent property and use check if paren't id is set instead

number enums

code cleanup: assign values to enums in DNA

typo/style edits

- remove redundant NULL checks from mallocn's local linked list functions.
- minor changes to warning cleanup.

initial support for editing masks in the sequencer, currently only draw the mask.

remove casts to short when allocating new imbufs.

new sequence strip type for masks.

Quite some warnings...

Remove unused ibuf argument from draw_gpencil_2dimage

It was used by sequencer only and it wasn't ported for a while already.
This change allows to save cahce lookup for image and clip editors.
