0f8f494d63 Fix T49296, assert failure in Bevel code. 
The mesh interpolation function failed to fill a fractions-of-the-way
array properly when the distances are very small but nonzero.

e3b5aa9bb1 Fix Bevel crashes T49088 and T48858. 
Was calling the fast path for finding edge order in cases
where it should not have been called.

0a026033ae BMesh: make toolflags optional 
Saves 8 bytes per vert/edge/face.
Gives overall ~20-25% memory saving for dyntopo sculpting
and modifiers that use BMesh.

e6d947f037 BMesh Intersect: use flags to keep track of verts 
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.

d9a01a1d04 Fix T48707: Edit-mesh intersect crash 
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).

5ea27bec1f BMesh Decimate: use doubles to calculate optimized position

543c64ef74 Fix bug where corner boundary was straight when it should curve. 
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.

7928030eff Fix T47257: bevel crash when there are internal faces. 
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.

c6c223ade6 Fix T47164: [Scene.raycast] - True result when it should be False. 
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).
