e525a06800 BMesh: only remove loose geometry when joining faces 
Joining faces could remove faces that happened to share an edge that would normally be removed.

e0e7d94f79 Fix error introduced by removing faces before executing bridge 
Commit 86abddc9, caused an error when the face-region included boundary edges.
Since removing the faces first, caused the edges along the boundaries to be removed.

Add support for deleting faces and internal edges, that keeps boundaries.

0b5a0d8412 Transform/Snap: EditMesh/BKE_bvhutils API improvements 
Separate the creation of trees from EditMesh from the creation of trees from DerivedMesh.
This was meant to simplify the API, but didn't work out so well.

`bvhtree_from_mesh_*` actually is working as `bvhtree_from_derivedmesh_*`.
This is inconsistent with the trees created from EditMesh. Since for create them does not use the DerivedMesh.

In such cases the dm is being used only to cache the tree in the struct DerivedMesh. What is immediately released once
bvhtree is being used in functions that change(tag) the DM cleaning the cache.

- Use a filter function so users of SnapObjectContext can define how edit-mesh elements are handled.
- Remove em_evil.
- bvhtree of EditMesh is now really cached in the snap functions.
- Code becomes organized and easier to maintain.

This is an important patch for future improvements in snapping functions.

6d0cae56e8 Fix T48290: Hook fails after deleting geometry 
Now CD_SHAPEKEY_INDEX customdata is stored in edit-mode when hooks and vertex parents are used.

This also fixes a bug where undo would loose key-index data.

Move to structs for BM_mesh_bm_to/from_me to avoid passing many argument, which mostly aren't used.

now use the first match instead of the last.

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).

8cd7b42877 BMesh: Add option to use BMesh boolean modifier 
This uses a bmesh-intersection, BLI_kdtree and watertight intersections to perform boolean operations.

For now keep both BMesh and Carve booleans usable at once for testing & bug reports,
however we plan to phase out Carve by next release.
