fix [#30090] Cloth modifier related crash when loading old file

own fault when adding int64 support. `void` type was being used to workaround a different bug in the ClothSimSettings struct.

Correct mathutils documentation, also correct some python spelling errors and add makefile target `check_spelling`

Code cleanup: spelling fix, Tesselection->tesselation

Fix #30081: the fix for #30026 related to rendering indirect/environment light
with material ambient zero broke backwards compatibility too much. The behavior
to have ambient zero affect things even if it is not used as a factor does not
make much sense but keeps things compatible. Now instead fixed the use of
uninitialized memory.

Fix #30061: cycles single render layer through python operator parameter not
working.

Returned back maximal value of bitrate. Higher values are actually makes sense with DNxHD only.

Fix for wrong pixel format used for qtrle

Fix #30089: crash with cycles viewport rendering while in text edit mode.
Cause was Object.to_mesh(), which could cause invalid memory access when
calling it on text objects in edit mode.

Style Cleanup:

replace 0/1 with TRUE/FALSE define.

Fix #30049: cycles noise texture producing nan values with some
texture coordinates, due to int overflow.

Also minor tweak in shader code to avoid copying uninitialized
values, should have no effect though because they were not used.

Fix #30086: cycles background render printing same status text twice.

FFmpeg output fixes and small improvement

Most part of this commit fixes issues with FFmpeg output with
currently supported codecs:

- avcodec_encode_video might return zero which doesn't mean error
happened, but blender will handle this as error and will stop
rendering to video file.
- Changing output video codec wouldn't update "expert" options
set for video output which leads to some sideeffects like
ignored Lossless option for x264 codec.

This fixes allowed to add QTRLE codec easily.

remove BMFlagLayer.index, (saves 4 bytes of memory per vert/edge/face)

Fix #30076: RenderLayer area blocks mouse scrolling

In fact all list templates used to block mouse scroll. It's because mouse
scrolls list's scroll bar. But mouse scroll also used to be "eaten" even
if there's no scroll in list template.
This commit makes scroll even be ignored by list templates if there's
no scroll bar on list.

internal change to bmesh_jfke():

remove last use of BMFlagLayer.index, instead use a flag to tag the vertices.
this loops over face loops too less times as well.

Style Cleanup

speedup for edge split modifier/operator
- don't call 'del' operator now, expose the internal function instead.
- use the index values stored in the header rather then the operator.

Fix [#30099] Wrong python path returned. "bpy.data.keys" instead of expected "bpy.data.shape_keys".

The "plural" name for ID_KE was wrong in idcode.c (bke), not matching the MainCollectionDef one used in rna_main.c.

Checked the others too, everything seems ok now.

Code Cleanup:
rename BM_remove_tagged_* --> BMO_remove_tagged_*

also make the delete flag to check into an argument.
