Change edgeloop delete to use dissolve, fixes bug [#35738].

Was using edge-slide & remove-doubles but this was error prone since remove doubles could fail in some cases or find doubles where it shouldn't (with very small scale objects).

This gives more predictable behavior when the edges of a loop wouldnt slide (in that case they would just drag over to one of the sides with no user control)
and multiple edge loops work better too. eg:

bmesh edge dissolve: add option use_face_split (matching vertex dissolve option),
useful to avoid odd shaped ngons surrounding dissolved edges.

BGE: Fixing a bug that caused KX_GameObject.localTransform to give incorrect results.

Fix blender internal showing SSS preprocessing status message even if there isn't
any SSS material in the scene.

Fix #35634: weight paint did not do z-buffer culling anymore on Windows after recent change to size of bool.

fixes for using scaled cameras
- ED_view3d_from_m4() got incorrect rotation from scaled cameras, was noticable with smoothview transitions.
- when you lock the camera to the view, any view edits would reset the cameras scale to 1.
- another problem with view locking if the camera was scaled and had a parent, the parent would be transformed incorrectly.
- fly mode was chaning object scale a little over time, now restore after applying scale so it never changes.

Fix #35664: blender internal material index pass + ztransp + multiple materials
assigned to a mesh did not work correct.

Fix #35735: blender internal viewport rendering was missing SSS update when
changing angle of view.

Fix #35730: cycles not rendering dupliverted metaball, needs another special
exception.

Rephrased error message for clarity

minor edits to world_to_camera() utility function, include Z so you can tell if the points in font of the camera and avoid divide by zero.

Fix #35729: cycles normal maps not showing properly in preview render.

handy function for getting the 2d camera coords for a worldspace location.

bpy_extras.object_utils.world_to_camera(scene, obj, coord)

Fix #35733: lamps on render layers that are both excluded and used for masking
should not be used, same as emissive meshes.

code cleanup: also fix crash in GPU_state_print(). and confine to debug mode builds.

Added NULL check for socket type make_socket_interface

Without this check it's easy to crash blender by passing
non-existing socket type to sockets.new() function.

fix for pythons __dir__ returning registrable functions on class instances (which may not have the functions defined).
gave odd behavior of including members in __dir__ that couldn't getattr()

Removed the Material Boundary option from the edge detection options in
the Parameter Editor mode. The Material Boundary toggle button takes
effect only in the Python Scripting mode. Instead the Parameter Editor
mode automatically determines which edge types need to be computed on the
basis of user-specified line selection criteria in terms of edge types.

Problem report from Light BWK through personal communications, thanks!

Fix crash in movie clip node when ibuf fails to load.

Was a stupid mistake in another fix here :(

Safety check for NodeTree.links.new function: Added NEVER_NULL flags to from_socket/to_socket arguments to make sure the function doesn't crash when passing None/NULL.
