Cycles: Report currently sampling tile when CPU is working on the last tile

This is mainly useful for the render farms output when logging might stop at
the "Path Tracing Tile N/N" string, which makes it a bit difficult to follow
what exactly is happening (node going crazy, hardware issues or just last tile
is too much heavy).

This is more like an experiment, might be changed in the future.

Return non-zero exit code when running blender from the command line and reading file has failed

This way automated scripts can actually see if some issue happened.

Cycles: Don't show devices which does not support OpenCL 1.1 in the menu

They'll be checked for the version later and that check will fail anyway,
so better to not allow user to see unsupported device in the list.

Also corrected one more issue with the device enumeration.

Assert when relative paths are passed to IO ops

This is typically an error (& hangs a few seconds on win32), best catch early.

Transform: Improve UV creation efficiency

- was doing 2x spin-locks, multi-view check and hash-lookup per face-corner.
- avoid doing customdata layer lookup per face.

Freestyle: Fix for wrong assertion failure upon inverted face normals.

The assertion code was not taking quad faces into account.

BGE: remove outdated doc of KX_PolygonMaterial, update doc of KX_BlenderMaterial

This patch suppresses the outdated KX_PolygonMaterial.rst documentation file and moves the example contained in it into KX_BlenderMaterial.rst.
The file KX_BlenderMaterial.rst receives some extra formatting changes (lists are not supported in methods arguments types).

Revert "Fix/Workaround T44662: Freestyle gives no visual output when the Save Buffers option is enabled"

This reverts commit ab417f31f403d74a76fb51fbd6e2aa3f706e15f1.

This workaround caused serious memory corruption issues which is not really acceptable
for the release. We'll be likely sticking to a more limited release when using freestyle
with saved buffers for until proper solution is implemented.

Fix T44682: Save Buffers canceled renders show nothing in Image Editor

The issue was caused by render pipeline freeing render parts prior to finishing
exr file writing which resulted in unfinished parts not being written into the
file by save_empty_result_tiles().

As a temporary solution we do explicitly write unfinished parts as empty tiles
to the exr file prior to freeing parts.

Not ideal solution, but should work for the release.
