Fix T53513: Particle size showing in multiple places

Technically this was introduced in 01b547f9931970050e when
exposing size and randomness for particles.

This "fixes" makes sure particle size and size randomness is always in the
Render panel when it affects the particle system (i.e., always unless using
advanced hair or hair that is not rendering groups/objects).

Fix T53639: text sequence strips no stamped into render.

Fix MSVSC2017 error

The last compiler version needs this include

bpy_extras: add missing colorband keymap to keyconfig_utils.py

fixes failing ctest script_load_keymap

Fix missing SpinLock typedef on macOS

Fix T53068: AMD Threadripper not working well with Blender

The issue was caused by SpinLock implementation in old pthreads we ar eusing on
Windows. Using newer one (2.10-rc) demonstrates same exact behavior. But likely
using own atomics and memory barrier based implementation solves the issue.

A bit annoying that we need to change such a core part of Blender just to make
specific CPU happy, but it's better to have artists happy on all computers.

There is no expected downsides of this change, but it is so called "works for
me" category. Let's see how it all goes.

Cycles: Fix compilation error of standalone application

Cycles: Fix compilation error with OIIO compiled against system PugiXML

Cycles: Fix compilation error with latest OIIO

There was some changes about namespaces, which causes ambiguities.

Replaces using namespace with an explicit symbols we need. Is good idea to NOT
pull in the whole namespace anyway!

Fix T52818: Tangent space calculation is really slow for high-density mesh with degenerated topology

Now we replace O(N^2) computational complexity with O(N) extra memory penalty.
Memory is much cheaper than CPU time. Keep in mind, memory penalty is like
4 megabytes per 1M vertices.

Mikkspace: Cleanup, reduce indentation level

Fix T53398: Surface deform modifier says that convex polygons are concave for big faces

Dot-product for angle check need either to be divided by vectors magnitude or be
calculated for normalized vectors.

Fix T53499: Cannot load DPX files

The issue was caused by unspecified color transfer. New behavior gives same
result as other viewers here, so likely is fine :)

Fix T53007: OpenSubdiv + transparency = artefact/crashes

Fix T52940: VSE Glow Effect Strip on transparent images has no blur
