Fix [#36538] Discontinuity (Euler) Filter - never ends - (deadlock?)

Code could enter in an infinite loop when curve value was an odd multiple of PI (i.e. 180°)...

Current code was also factorized and got rid of fabs calls! ;)

math api edits - replace point-normal form for a plane with dist_to_plane_v3()
also correct python mathutils api, was missing vector checks.

Cycles: more code refactoring to rename things internally as well. Also change
property name back so we keep compatibility.

Cycles: change Progressive sampling option in UI to an enum of "Path Tracing"
and "Branched Path Tracing", to try to make it more clear that this is not
related to progressive refinement, non-progressive was always a bad name anyway.

Fix clang compile warning.

new mesh bisect had a problem not selecting faces with fill option in face mode.

fix error in recently added symmetrize rewrite, verts already on the aligned to the mirror-plane would not be welded.

fix leak in BM_face_split() with multires if the split failed.
also remove redundant normal copy.

only triangulate the mesh if its needed when enabling dyntopo.

Code cleanup / Cycles:
* Some style tweaks for hair code.

new mesh bisect tool, available in the mesh menu.
cuts the mesh in half based on the cursor location and the viewport,
optionally supports filling the cut area (with uvs. vcols, etc),
and removing geometry on either side of the cut.

Cycles / Sampling UI:
* Do not show Total Samples print for Progressive, when Square Samples are disabled. In this case it's obvious even without the print. :)

correct error in recent commit triangle-fill-dissolve, need to check if the edges face is removed (happens in rare cases).

* Compile fix for r59395, 'move bmesh tools into their own include'.

_another_ fix for recently added bisect operator, looping over mixed geometry could read freed memory when vertices were removed.

add dissolve option to triangle fill operator, running dissolve after scanfill isn't so simple because of errors if one edge can't merge.

fix for error in recetly added bisect operator, in rare cases it could attempt to remove vertices twice.

optiona for bmesh triangle fill operator to take a normal argument

set function args in BLI_math_rotation as const where possible.

Tracking cleanup

- Collapse plane track panels by default
- Hide 3D markers when in mask edit mode
- Remove alpha from mask layers list

Discussed with Sebastian and Roman.

Tracking Python API improvements

- Solved issue with changing marker's frame number
for tracks which doesn't belong to camera object.

- Support find_frame, insert_frame and delete_frame
functions for plane markers.
