Fix "make deps" error when building deps with make and Blender with ninja

Fix BLI_array macro so can use BLI_strict_flags.h.

Was doing int comparision against size_t, so added casts.

GPU: Split gpu_shader_material into multiple files.

This patch continue the efforts to split the `gpu_shader_material` file
started in D5569.

Dependency resolution is now recursive. Each shading node gets its own
file. Additionally, some utility files are added to be shared between
files, like `math_util`, `color_util`, and `hash`. Some files are always
included because they may be used in the execution function, like
`world_normals`.

Some glsl functions appeared to be unused, so they were removed, like
`output_node`, `bits_to_01`, and `exp_blender`. Other functions have
been renamed to be more general and get used as utils, like `texco_norm`
which became `vector_normalize`.

A lot of the opengl tests fails, but those same tests also fail in
master, so this is probably unrelated to this patch.

Sculpt: New brush cursor, active vertex and normal radius

This commit includes the new brush cursor, active vertex updates and the normal radius brush property for all sculpt brushes.
-The new brush cursor previews the real stroke radius over the mesh and the sampled sculpt normal.
-The active vertex is used in sculpt tools and brushes as a starting point for an operation, similar to a preselection. It is also mirrored following the enabled symmetry options to preview the stroke symmetry.
-The normal radius brush property limits the radius that is going to be used to sample the sculpt normal and area center. It controls how closely the cursor follows the surface and it improves the behavior of most brushes, making them suitable for hard surface sculpting.

Install_deps: Do not take sub-versions '6' numbers of RHEL/CentOS versions as main '6' version.

Windows: Move building of blendthumb into the blender codebase.

Previously this was done in the deps builder due to the fact we needed
both 32 and 64 bit versions of this dll and CMAKE does not support that
in a single build folder. Now that 32 bit support has been dropped, this
can be safely moved into the codebase.

Cycles: OpenCL Separate Compilation Debug Flag

OpenCL Parallel compilation only works inside Blender. When using cycles in a different setup (standaline or other software) it failed compiling kernels as they don't have the appropriate Python API and command line arguments.

This change introduces a `running_inside_blender` debug flag, that triggers out of process compilation of the kernels. Compilation still happens in subthread that enabled the preview kernels and compilation of the kernels during BVH building

Fix interger number buttons increment/decrement arrows not working in
some cases

Since rB78b56fa7d973 defining a button with 'but->a1 = 0' wasnt
automatically setting its step value to 1 in 'ui_do_but_NUM' anymore.
Instead of handling this more forgiving in 'ui_do_but_NUM', went over
the remaining cases of buttons and and defined them with a step value of
1.
