Use expanded names for bmesh primitive operations
(urmv jvke semv jfke).
Use 'bmesh_kernel_' prefix,
these functions aren't intended for wide use so favor readability.
Remove BM_face_vert_separate,
it wasn't used and only skipped step of finding correct loop of face.
Please **DO NOT** add changes from master when it's totally uneeded!
Changes to BLI_ area most certainly shall *always* be done in master,
there is absolutely no point in adding more diff between the two
branches than needed, will only makes merging more cumbersome!

This is the same issue as was fixed with T39486: the adjustment pass
that tries to equalize different widths at either end of an edge
sometimes causes the widths to get bigger and bigger.
The previous fix was to let "clamp_overlap" do double duty as a way
to limit this behavior. But clearly this is undiscoverable, as the
current bug report shows. So I put in an "auto-limiting" mode that
detects when adjustments are going crazy and then acts as if
clamp_overlap were set.
The reason we can't always act as if clamp_overlap is set is that
certain models (e.g., Bent_test in regression tests) look bad if
that is enabled.
Just return the face or NULL, like BM_edge_exists(),
Also for BM_face_exists_overlap & bm_face_exists_tri_from_loop_vert.
No functional changes.
Old code did some partial overlap checks where this made some sense,
but it's since been removed.
For simple cases bitmasks were OK, but didnt work for vert/edge, vert/edge tests.
Tag verts instead, makes logic easier to follow and gives minor speedup.
In rare cases intersect would attempt to add edges with the same vertex twice
from edge-vert / edge-edge intersections.
Solve by checking for duplicates when creating vertex-array for these types of intersections
(always under 3x comparisons, so not much overhead).
Some adjustments to how bevel edge 'profiles' are adjusted in some
cases. For the bug fix, wanted to handle cases of middle of three
coplanar beveled cases to make profile curve rather than linear
interpolate.
Also undid an earlier decision to make profile plane be perpendicular
to beveled edge i the non-coplanar case.
Bevel had assumed that when rebuilding a face that touches
a vertex with beveled edges, the edges of the face at that vertex
would be adjacent in internal order. That is not necessarily true
if there are edges with more than two faces attached.
We could just prohibit beveling any edges that touch a vertex
where this happens (we already don't bevel non-manifold edges)
but the use case in the model of T47257 seems reasonable.
Also had to fix the edge-ordering code, and the face reconstruction
code to take care of cases where the face normal may not be as expected.
Holes with flat surfaces could have their edges dissolved causing degenerate faces.
Now check that collapsing a vertices isn't creating self-overlapping faces.
We cannot use FLT_MAX as initi distance for raycast...
Renamed TRANSFORM_DIST_MAX_RAY to BVH_RAYCAST_DIST_MAX, moved it into BLI_kdopbvh,
and use in RNA raycast callbacks (and all other places using that API).
