Task scheduler: Start with suspended pool to avoid threading overhead on push

The idea is to avoid any threading overhead when we start pushing tasks in a
loop. Similarly to how we do it from the new dependency graph. Gives couple of
percent of speedup here, but also improves scalability.

Task scheduler: Clarify why do we need an atomic add of 0

Cycles: Fix crash opening user preferences after adding extra GPU

We can not store pointers to elements of collection property in the
case we modify that collection. This is like storing pointers to
elements of array before calling realloc().

Cycles tests: Add extra image tests

Fix T53012: Shadow catcher creates artifacts on contact area

The issue was caused by light sample being evaluated to nan at some point.
This is root of the cause which is to be fixed, but is very hard to trace down
especially via ssh (the issue only happens on AVX2 release build). Will give it
a closer look when back to my AVX2 machine.

For until then this is a good check to have anyway, it corresponds to what's
happening in regular radiance sum.

Fix retro-futuristical atempt to include some keymaps for non-backported feature from master.

Was making unittests unhappy.

Revert "Node selection: Stop operator when mouse selection selected a node"

This reverts commit bf58ec9265eef8c6cd3dc350557829151995ef28.

Cycles: Fix difference in image Clip extension method between CPU and GPU

Our own implementation was behaving different comparing to OSL and GPU,
namely on the border pixels OSL and CUDA was doing interpolation with
black, but we were clamping coordinate.

This partially fixes issue reported in T53452.

Similar change should also be done for 3D interpolation perhaps, but this
is to be investigated separately.

Fix T53850: Lock to Cursor breaks 3D manipulators

Fix manual lookups (data is now lowercase)

Fix old files with changed node socket type not loading correctly.

This would lead to sock.default_value pointing to the wrong data type,
possibly causing crashes. Unfortunately, this bug will still exist for
older Blender versions that try to load newer files, which makes
changing the type of a node socket problematic.

crash fix at fracturing, customdata layer index handlng was incorrect

Fix T53832: Particle weight paint crash

Drawing hair weights read before the hair array start.
This code could be improved since it currently copy-pastes,
from do_particle_interpolation, but this would need larger changes.

For now just correct existing logic.

Fix T53823: Particle weight brush crash

Entering particle edit mode w/ the weight brush enabled crashed
on non-hair particle systems.

Fix memory leak in recent curve refactor

Fix buffer overflow vulnerability in curve, font, particles code.

Solves these security issues from T52924:
CVE-2017-12102
CVE-2017-12103
CVE-2017-12104

While the specific overflow issue may be fixed, loading the repro .blend
files may still crash because they are incomplete and corrupt. The way
they crash may be impossible to exploit, but this is difficult to prove.
