Fix T45937: Cycles hair not rendered if children count set to zero

Cycles: Fix missing packed images with newer versions of OSL

This isn't really complete fix, complete fix would require calculating
derivatives via OIIO API, but supporting this will either end up with
some code duplication or will require some non really safe changes at
this release cycle.

Fix T45946: Cycles texture interpolation bug

Coordinate clamping was done in the wrong order.

BGE docs: resolution & fullscreen changes don't work in the embedded player

The documentation for bge.render.{setWindowSize,setFullScreen,getFullScreen}
did not mention that those functions are no-ops when using the Blender-
embedded player.

PyAPI: tweak to ensure_ext don't lower entire path

Fix: Made bpy.path.ensure_ext compatible with compound extensions.

Extensions such as ".tar.gz" are now also supported. Before this patch,
ensure_ext('demo.tar.gz', '.tar.gz') would return 'demo.tar.tar.gz'.

This results in issues with the `ExportHelper` mix-in class; clicking
an existing file in the file dialogue warns about overwriting it
(highlighting the input box in red), but then saves to a different
file.

Also added a unit test for the new behaviour.

Fix T45984: Setting custom normals properly requires multiple calls to normals_split_custom_set()

The detection of needed sharp edges (based on given loop normals) would not fully work
on first run in case we started with a complete smooth cyclic loop fan (edge between
first and last loop of the fan would not get checked).

Cycles: Fix nondeterministic pass ordering when using baker

Cycles: Fix for uninitialized closure data

This might confuse closure merger.

Spotted by Campbell Barton, thanks!

ImBuf: Fix crash generating preview for really huge image

In fact, any user of IMB_scalefastImBuf() is now robust against working
with really hires images.

Compositor: Support changing distortion models in movie distortion node

Previously only polynomial model worked correct. now changing it to divisions
will work nicely as well.

Fix T45959: DistanceKey preview used wrong colors

Same issue as recent fix in ChannelMatte

Animplayer passed -a, then warned its unknown

Also modify a copy of argv

Fix T45979: animplayer crashes w/ DND and audio

Issues re-initializing audaspace

Fix second part of T45987: Node preview was still using wrong color space

Fix T45995: Auto-set preview range sets superfluous end key.

get_keyframe_extents() would add an extra frame in case of mono-key fcurves in selected set...

Now do the 'not same start/end frames' check later, and also use floor/ceil instead of round
(we want to start at frame 3 if first key is at frame 3.8, reversed-same goes for end frame).

CMake: use generator expressions

CMake: Fix building w/o FindGit

Add missing spin-lock to IMB_makeSingleUser

Fix T45991: Transfer Weight tool UI is inconsistent and crashes blender.

Since data transfer when called from this tool has reversed behavior (it transfers **towards**
active object, as previous tool), we have to also reverse source/destination layers selection options.

Also fix 'reverse' option being saved, otherwise calling regular operator after 'transfer weights'
would stay in reverse mode, ugly!
