Fix MSVC compiler warning due to using */* to start comment.

Cycles: Support earlier tile rendering termination on cancel

It will discard the whole tile, but it's still kind of more friendly than
fully locked interface (sort of) for until tile is fully sampled.

Sorry if it causes PITA to merge for the opencl split work, but this issue
bothering a lot when collecting benchmarks.

UPBGE: Fix crash when calling shade_light texture when mtex has no tex.

Fix T49478: triangulate of face hangs Blender.

Another case of float imprecision leading to endless loop. INcreasing a bit 'noise threashold' seems to work OK.

Not a regression, but might be nice to have in 2.78a.

Cycles: Fix compilation error with minimal feature set

[MSVC] make.bat updates.

- The build folder name used to be depended on the order of the parameters, this is now normalized to
"build_windows_[Release/Full/Lite/Headless/Cycles/Bpy]_[x86/x64]_vc[12/14]_[Release/Debug]" regardless of the order of the parameters.

-Use CUDA8 for all kernels when building the release convenience target with visual studio 2015

Fix T49460: Particle group instance 'Use Count' value gets reset on file-load.

Regression caused rBbcc863993ad, write code was assuming dw->ob was always valid,
wich is no more the case right after reading file e.g.

Another good example of how bad it is to use 'hidden' dependencies between datablocks. :(
And another fix to be backported to 2.78a. :(((

Fix T49471: Vertex Connect randomly broken.

Not sure where this comes from, but code was converting BMEdge* to BMVert* to check oflags,
i.e. not accessing correct memory.

Regression, to be backported to 2.78a.

Fix T49423: Data Preview of group containing only group instances is empty.

Code was not getting correct boundbox in some cases (group only instancing other groups e.g.), now
compute our own bbox in those cases.

Based on patch by @lichtwerk, but extended the fix to include linked datablocks in some cases
(linked objects in local groups, linked objects in local scene, etc.), this was also broken in existing code.

Fix T49461: Dynamic paint wetmap flickers.

Regression from rBa4a968f, we would adjust current point's wetness without actually protecting it
in new multi-threaded context, leading to concurrent access mess.

Now delay applying wetness reduction to current point to end of function, allows us to avoid having
to lock current point twice together with neighbor one (and reducing spinlock awainting too).

To be backported to 2.78a.

Update source tgz builder script

Was broken since splitting BKE_blender_version from BKE_blender.

Fix T49466: Stupid typo in logicbricks new copy code from rB776a8548f03a

Moved that code forth and back a few times while creating rB776a8548f03a fix,
ended up forgetting to update it correctly for function where it layed down in the end.

Last-minute fixes are never a good thing... Now we already have real reason for 2.78 'a' release :(

Buildbot: Another attempt to have OSX builder fixed

Fix export image generated by export UV layout

Was only happening with new dependency graph.

The issue here is that scene's depsgraph layers will be 0 unless
it was ever visible. Worked around by checking for 0 layer in the
update_tagged of new depsgraph. This currently kind of following
logic of visible_layers, but is weak.

Committing so studio is unlocked here, will re-evaluate this layer.

Buildbot: Temporary disable CUBIN compilation

Cycles: Move BVH constants to an own files, so they are easily re-usable

Buildbot: Disable QuickTime for the time being

Buildbot machine was updated to the new SDK which seems to have
QTKit removed.

For until we've installed older SDK or ported our code to a new
AVFramework disabling QuickTime.

[Windows/make.bat] Clean only after all parameters have been processed so the full path is known, and require a convenience target to be set. Also added a helpful error message if any of the required data is not available.

Cycles: Cleanup file headers

Some of the files were wrongly attributing code to some other
organizations and in few places proper attribution was missing.

This is mainly either a copy-paste error (when new file was
created from an existing one and header wasn't updated) or due
to some refactor which split non-original-BF code with purely
BF code.

Should solve some confusion around.

Fix Scene datablocks being created with a real user while never having any real datablock user.

Now using new system dedicated to that kind of cases, id_ensure_real_user(), instead.
That way, usercount of Scenes is handled correctly at deletion time.

Reported by @sergey over IRC, thanks.
