Fix T48829: Memory leak on Blender Exit

It was possible to have missing outlink but GPUNodes in material.

Fix T48950: Movie Clip mode segfaults

Missing linking code in blenloader.

Correct UI names of ID types

Also correct typo.

More useful block name for report popup blocks

Report popups simply reuse popup menu code, so their blocks got "UI_popup_menu_begin" assigned as name, which was a bit misleading. Now uses "UI_popup_menu_reports".
Ideally they'd have their own popup code.

Fix T45936: invalid cycles motion blur for particle rotation and children.

Commit rB709ca0ece changed how rotation was handled for particles so
that unless actual rotation physics is enabled, there is no rotation.
However it only updated ptcache_particle_read, forgetting to change
exactly the same code in ptcache_particle_interpolate.

This means that for subframes old code that computes a rotation from
velocity is used, resulting in completely different rotation than for
integer frames. This causes rotational motion blur by itself, and also
mangles motion blur paths of child particles.

Fix T48813: Custom icon is not drawn on header / addons prefs panel.

For now use 'brute force' and refresh whole UI when new icons get rendered.

See comment of T48813 for ideas about how to handle that in future (2.8 project ?).

Cycles: Proper fix for buffer overflow in volume intersect all

Cycles: Revert previous fixes to intersect_all functions

While they prevent legit write past the array boundary error
those fixes introduced regression in behavior when having exact
max_hits transparent intersections and nothing else.

Previous code would have considered such case a totally opaque,
but it's not correct.

Fixes T48941: Some materials don't get transparent shadows anymore

Fix issues in ID usages checks - we are not interested in self-usages here.

Drivers or constraints referencing self object could break deletion of proxy objects
(due to their ambiguous, half-local, half-linked status).

Fix T48902: MCE Dopesheet does not respect Left Click select

Make the operator consistent with animation dopesheet now.

Depsgraph: Use proper check whether ID is an object

Fixes bug which resulted in making it so layers from all
layers are getting updated.

Reported by Juan Pablo Bouza.

Depsgraph: Use proper unsigned int bitfield for layers flags

Curve Drawing: use more closely spaced samples

Re-fitting makes better use of more samples.

Resolve undefined M_PI w/ MSVC2013

Call to python3 for stand-alone scripts

Needed since Debian & FreeBSD both move away from keeping a synlink to `python`.

OpenSubdiv: Fix opensubdiv option obscuring the interface

Cleanup: factorize the 'ensure local' part of datablock copy into a single BKE_id_copy_ensure_local function.

Cycles: Fix rays parallel to the surface in the triangle refine and MultiGGX code

In the triangle intersection refinement code, rays that are parallel to the triangle caused a divide by zero.
These rays might initially hit the triangle due to the watertight intersection test, but are very rare - therefore, just skipping the refinement for them works fine.

Also, a few remaining issues in the MultiGGX code are fixed that were caused by rays parallel to the surface (which happened more often there due to smooth shading).

Cycles: Calculate differentials in the Multiscattering GGX closures

The Multiscattering GGX closures didn't set the omega_i differentials, which could cause undefined behaviour.

OpenSubdiv: Support shadeless shading
