Fix fixed width box layouts

Regression, to be backported in 2.79.

Orthographic projection now fixed as well as wrong stroke boundingbox calculation. Ring calculation might need a different approach.

Cleanup: mostly namings in `make_object_duplilist_real` code.

Fix T52260: Blender 2.79 Objects made duplicates real still refer armature proxy.

New code was handling correctly ID's internal references to self, but
not references between 'made real' different objects...

Regression, to be backported in 2.79.

Fix T52255: New Depsgraph - Constraint and Drivers not working together when the driver references itself

Depsgraph: Cleanup, make it easier to debug on laptop

Cycles: Cleanup, de-duplicate function parameter list

Was only needed to sue const reference on CPU. Now it is done using ccl_ref.

Cycles: Add utility macro ccl_ref

It is defined to & for CPU side compilation, and defined to an empty for any GPU
platform. The idea here is to use this macro instead of #ifdef block with bunch
of duplicated lines just to make it so CPU code is efficient.

Eventually we might switch to references on CUDA as well, but that would require
some intensive testing.

Fix T46329: scene_update_{pre,post} doc needs clarification

The documentation for the bpy.app.handlers.scene_update_{pre,post}
handlers states that they're called "on updating the scenes data".
However, they're called even when the data hasn't changed. Of course
such handlers are useful, but the documentation should reflect the
current behaviour.

Fix width estimation for empty layouts in pie menus

Update CUEW to latest version

Previous update pulled too much of system-wide typedefs.

Fix T52263: Crash When Splitting and Merging Areas with Header Text Set.

Not a regression, but safe enough to be included in 2.79.

Update CUDA wrangler to latest version

Brings new declarations from toolkit version 8.0, also fixes some
pointers used in function declarations.

Cycles: Pack kernel textures into buffers for OpenCL

Image textures were being packed into a single buffer for OpenCL, which
limited the amount of memory available for images to the size of one
buffer (usually 4gb on AMD hardware). By packing textures into multiple
buffers that limit is removed, while simultaneously reducing the number
of buffers that need to be passed to each kernel.

Benchmarks were within 2%.

Fixes T51554.

Fix compilation error when building without Blender

Simply disabled python tests, they can't be run anyway (since blender target is
not enabled) and we don't have any player-related tests in that folder.

Cleanup: remove incorrect comment

enum values aren't saved in files.

Fix CMake dependencies builder issues on Linux with TBB and Python packages.

using quaternions and correction of quaternion sign flips for convert to keyframes now

Merge branch 'master' into blender2.8

Stupid git handles merges terribly when there are conflicts and branch
is modified buring merge process... :((((

Cycles: Cleanup, move curve intersection functions to own file

This way curve file becomes much shorter and it's also easier to write a
benchmark application to check performance before/after future changes.
