Compiling this big file for every Eevee material is bad for performance, and
now that we are adding more nodes it gets worse. This patch adds a simple
mechanism to split up that file, and use only the parts used by shader nodes.
When a function is used by GPU_link, we detect which GLSL file it came from
and use it in GLSL code generation automatically. Dependencies between GLSL
files are manually specified, and function names must be unique across all
GLSL files.
Most of the actual splitting up will be done in later commits.

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.

Previously, we had one global `GPU_matrix` stack, so the API was not
thread safe. This patch makes the stack be per `GPUContext`, effectively
making it local per thread (`GPUContext` is located in thread local
storage).

Alpha blended Transparency is now using dual source blending making it
fully compatible with cycles Transparent BSDF.
Multiply and additive blend mode can be achieved using some nodes and are
going to be removed.
Recently Shader parameter names for UVMaps and vertex colors were renamed.
The sculpt drawing code still used the old parameter names.

The problem is that the `glDrawArraysInstancedBaseInstance` is ignoring the last parameter.
The solution is to indicate that `GLEW_ARB_base_instance` is not supported in these cases.

When using opengl attributes such as gl_VertexID in a shader its
location is set to -1. This location was used without checking in an
attribute array. This fails big time when called from python. For
example `print(shader.format_calc())` made python crash immediately.

Migrate old legacy code to the draw mamager/object mode. The old legacy
version did not work with wireframe. By migrating the code
to modern draw manager code we have mode control on the drawing process.
Still background images do not work with OIT, the cause seems to be that the transparent pixels are treated as background pixels.
Also There are some artifacts when working with Holdouts and DoF, this
is because the draw engines do not pass the correct alpha values.

Use depth buffer to order the uv edges correctly to always draw selected
edges on top.
We still use the double drawing workaround for points to keep the smooth
antialiased display.
The issue was caused by a bad usage of GPUOffscreen.
The Framebuffer was created using a window framebuffer and used
in a viewport callback when another GPUContext was bound.
This change allows up to 3 framebuffers per GPUOffscreen.
Most common case will be using 2 framebuffers (one for init and
one for drawing) but in the case of more (bad usage) it will just
degrade performance a bit.
Now texture storage of images is defined by the alpha mode of the image. The
downside of this is that there can be artifacts near alpha edges where pixels
with zero alpha bleed in. It also adds more code complexity since image textures
are no longer all stored the same way.
This changes allows us to keep using sRGB texture formats, which have edge
darkening when stored with premultiplied alpha. Game engines seems to generally
do the same thing, and we want to be compatible with them.
This is a mix of solutions rBe60b18d51d58 and rB52af5fa31fbc.
What happened was that when a node of the BVH gets 0 vertices, the batch is untouched and therefore still drawn.
In the Intel HD 4000 driver a shader has to be deleted in the same context in which it is created.
However, because you can't use a rendering context on different threads, to maintain the multithreaded compilation, the solution was to use the `GL_ARB_get_program_binary` and copy the binary generated for the shader and generate a shader on the main context using that binary.
This solution is limited only to Intel HD 4000 and windows.
