remove BM_ITER, BM_ITER_INDEX macros, use ELEM or MESH variants only (the maceros had unused args in both cases).

For bug #30931, change knife hardcoded colors to ones derived from theme.

For now, just reusing some theme colors that are there for other reasons
but matched approximately the colors used now.
Except that cut lines are now purple-violet, so that they contrast
with grid and edges better, especially in wireframe.

code cleanup: first step to replace BM_ITER BM_ITER_INDEX macros.

BMESH_TODO: xsort of vertices working again.

This commits adds a new function which can remap vertices/edges/faces of a BMesh in a new given order:
void BM_mesh_remap(BMesh *bm, int *vert_idx, int *edge_idx, int *face_idx)

style cleanup: BM_ITER / BM_ITER_INDEX / BMO_ITER

bmesh api function: BM_edge_face_tangent()
was used by inset but make into an api function since scripts can use this too.

Fix #30998: copy to selected in properties editor not working for bones.

Fix #31009: edge split did not split non-manifold edges correctly, it should
create a separate edge for each face.

Fix #31007: text editor delete at end of last line did unnecessary undo push.
Patch by Justin Dailey, simplified a bit.

Cycles: increase SVM stack size to allow more complex node setups, did not
find any slowdowns with the increased size.

fix bevel edge angle (wasnt hooked up to new code), vertex-bevel angle isnt working still

style cleanup: bevel code, also remove unneeded flag setting.

Fix for disabling noisy opennl output.

More info from bf-committers:

added function for copying weight to target vertex from closest source vertex

Fix: Mark seams in uv editor didn't work

Fixing bug [#31005] Nurbs UI bug
* W button was hidden, due to too small y alignment.

Release Status:
* Still BCon4, rc phase now.

knife tool: Add state indicator in header for tool options

improve recent commit to copy loop data on extrude
- in some cases the is only a face on the new edge, so check for this as a source to copy from too.
- one of the asserts wasnt correct, if there are no adjacent faces found just return.

bmesh knife tool: cut through no longer initializes from view setting to limit selection to front faces.

instead this is a toggle (Zkey) which is remembered between executions.
