Since OpenImageDenoise requires a CPU with SSE 4.1 or newer,
let the node act as passthrough on unsupported CPUs and display
a message in the node itself.
Add Multiply, Divide, Project, Reflect, Distance, Length, Scale, Snap,
Floor, Ceil, Modulo, Fraction, Absolute, Minimum, and Maximum operators
to the Vector Math node. The Value output has been removed from operators
whose output is a vector, and the other way around. All of those removals
has been handled properly in versioning code.
The patch doesn't include tests for the new operators. Tests will be added
in a later patch.

For clarity sake, the batch cache now uses exclusively per Loop attributes.
While this is a bit of a waste of VRAM (for the few case where per vert
attribs are enough) it reduces the complexity and amount of overall VBO
to update in general situations.
This patch also makes the VertexBuffers filling multithreaded. This make
the update of dense meshes a bit faster. The main bottleneck is the
IndexBuffers update which cannot be multithreaded efficiently (have to
increment a counter and/or do a final sorting pass).
We introduce the concept of "extract" functions/step.
All extract functions are executed in one thread each and if possible,
using multiple thread for looping over all elements.

The most common use of the text editor seems to be for scripting. Having
line numbers and syntax highlighting enabled by default seems sensible.
Syntax highlighting is now enabled by default, but is automatically
disabled when the datablock has a non-highlighted extension.
Highlighting is enabled for filenames like:
- Text
- Text.001
- somefile.py
and is automatically disabled when the datablock has an extension for
which Blender has no syntax highlighter registered.

Previously we were setting it to 1 (aka no 'chunking'), to follow
previous behavior. However, this is far from optimal, especially with
CPUs that can have tens of threads nowadays.
Now taking an heuristic approach (inspired from the one already existing
for `BLI_task_parallel_listbase()`, which tries to guesstimate best
chunk sizes based on several factors (amount of threads/parallel tasks,
total number of items, ...).
Think this is a reasonable base ground, more optimization here would of
course be possible.
Note that code that was already explicitely settings some value here
won't be affected at all by that change.
Function would not clear the static scheduler pointer, which lead to
crash (mem use after free) when trying to re-init and use the task API
again. Should not happen in Blender itself, but could in other cases
(like some future gtests ;) ).
Still needs a proper solution for older compilers with custom static assert.
macro that can conflict when there is an assert on the same line in multiple
files.
Some versions of the Windows SDK headers have a dbghelp.h that will emit
C4091 warnings, repress them just this once, since the warn can be helpful
in other places.
This patch makes BLI_task_scheduler_create wait for all worker threads to have started before
returning to caller. For very short workloads (BLI_taks_test) there is the chance that the
worker threads have not fully started yet, and the main thread is calling pthread_join at
the same time as pthread_setspecific is being called on the worker threads which causes a
deadlock on pthreads4w.
