correct error in face walker (was inserting into the wrong ghash which was immediately freed after)

cloth was using edgehash not quite correctly:
- was ordering vertex args unnecessarily.
- was adding the same edges multiple times into the edgehash.

cloth spring building: replace MIN2/MAX2 in assignments with a function which orders on assignment.

Fix issue in last subsurface commit with branched path tracing, was rendering too bright.

avoid double ghash lookup in sculpt map_insert_vert

add versions of BLI_ghash_int_new, BLI_ghash_str_new, etc. that take a reserve argument.

revert bucket size change (edgehash was this way for years, since r26206, ghash since r57657)
having 2 free buckets for each entry is faster but uses more memory.

use the original size, best case 3 entries per bucket.

Fix #36541: blender internal raytrace render hangs with high ray depth. The code
here is not efficient for such cases, a ray depth can give up to 2^depth rays due
to the ray splitting in two at each depth. A proper solution requires a better
algorithm, for now I've ensured that you can at least cancel such renders. The
overhead from the extra test_break is negligible.

Cycles: reduce noise using regular path tracing + subsurface scattering with
new cubic and gaussian falloff. Like the branched path tracer, this will now
shade all intersection points instead of using one at random.

use reserve argument for more edgehashs

fix for leak in cloth modifier
- any error in cloth_build_springs wasn't freeing the edge-hash.
- was checking BLI_edgehash_haskey on matching vertices.
- was looping over setting NULL for all elements of a calloc'd array.

Made large "blender icon" for save blends (.blend1, .blend2, etc.) have a bit darker background as well.

when the size of an edgehash is known or can be guessed,
pass in the argument to reserve the size.

Adding a darker "blender icon" for save blends (.blend1, .blend2, etc.), as requested by elubie.

fix for leak in make_edges_mdata() if there were no edges to create,
also reserve the total number of edges in the hash when its created.

edge hash: take an arg for the guarded-malloc string (as ghash does)

ghash and edgehash api, allow newly defined hashes to take in the size of the hash as an arg (avoids resizing in simple cases when the hash is created and filled immediately).

* fix old bug: wrong layout that could happen when switching between thumbnail view and list view. This caused the layout to be recalculated sometimes and the items being moved. Reason was that the layout was wrongly initialized without the scroll bars, so calculated wrongly.

fix for GPU_update_bmesh_buffers not setting bmesh vertex index values as dirty (could cause errors later).

Fix for [#36374] Read unitialized memory in Freestyle.
A variable keeping a bounding box was referenced after it was flagged as empty.
