BGE: Fix T40555: LibLoad material caching issue

Previously we don't merge material cached list, it create dangling pointer and memory leak.
Now we merge material cache list during the scene merge, and remove material in this list during the library free.

Fix part of T44768 Yet another Intel driver failing on viewport Ambient
occlusion

(Maybe we should add drivers that DO work instead, but in the future
those will be much more since Intel claims to have fixed the issue)

Clear animation list to avoid referencing freed memory.

Fix T44766: Connect fails /w selected ngon edges

BMesh: calls to store selection at the list head

BMesh: add BM_edge_pair_share_face_by_len

Fix T44755 set_value node output in node tree not properly converted to
color in GLSL

Issue here is that intermediate result was clipped as an optimization in
such nodes and thus not converted to the correct type properly. Now only
clip those values if types match.
This keeps both the optimization and the conversion. I looked at
converting uniform types always but it's more involved to compare types
at conversion time for such links because the type was getting
overridden during link duplication.

Fix T44553.

Front face option did not get the correct normals to function - area
normal would always point to the direction of the stroke

Fix T44762: Materials flicker in edit-mode

Fix T44759: Blender has problems reading and writing 42k images to PNG

Object Drawing: avoid redundant material update

BMesh: editmode drawing set every faces material

Check for changes in material (as other drawing code already does)

Cycles: Check for validity of the tiles arrays in progressive refine

In certain configurations (for example when start resolution is set to small
value for background render and progressive refine enabled) number of tiles
might change in the tile manager. This situation will confuse progressive
refine feature and likely cause crash.

We might also add some settings verification in the session constructor, but
having an assert with brief explanation about what's wrong should already be
much better than nothing.

Cycles: Check for whether update/write callbacks are set prior to calling them

This changes the progressive refine part, regular update was already checking
for whether callbacks are set.
