It has been tested that local shaders workaround isn't needed for the
latest Windows/Intel 6xx GPU's.
Currently the local shaders workaround doesn't work anymore during the
investigation it was detected that the intel drivers didn't need it
anymore.
Local shaders should still be fixed as it is also used for some legacy
iGPU's. The current work around crashes when doing preview renders in
EEVEE as the default materials aren't available but for the work around
they should. (See T77346 for more information)
Limit support for `GLEW_ARB_base_instance` to OpenGL 4.0 and higher. NVIDIA Quadro FX 4800
(TeraScale) report that they support GLEW_ARB_base_instance, but the driver does not support
`GLEW_ARB_draw_indirect` as it has an OpenGL3 context what also matches the minimum needed
requirements.
We use `GLEW_ARB_draw_indirect` as a target for `glMapBuffer(Range)` what is part of the
OpenGL 4 API. So better disable it when we don't have an OpenGL4 context.
Note: fix should be ported to Blender 2.83 LTS

This makes it easier to track as well as allowing us to sample the same
texture with different sampling parameters (which should fix the related
T73942 in the long run).

We implement cubemap array support for EEVEE's lightcache reflection probes.
This removes stretched texels and bottom hemisphere seams artifacts caused
by the octahedral projection previously used.
This introduce versioning code for the lightcache which will discard any
lightcache version that is not compatible.

- Move gpuPush/Pop from GPU_draw.h into GPU_state.h
as this is for pushing/popping state.
- Add 'GPU_STANDALONE' define, to bypass use of user-preferences
for theme colors and pixelsize, as well as pbvh init/free functions.
Needed to get GHOST tests working again.
Adds a check when starting blender if your platform is supported. We use a blacklist
as drivers are updated more regular then blender (stable releases).
The mechanism detects if the support level changed or has been validated by the user previously.
Changes can happen due to users updating their drivers, but also when we change the support
level in our code base.
When the user has seen the limited support level message it is saved in the user config.
It would be better to have a system specific config section, but currently not clear
what could benefit from that.
When the platform is unsupported or has limited support a dialog box will appear including a link
to our user manual describing what to do.
**Windows**
Windows uses the MessageBox that is provided by the windows kernel.
**X11**
We use a very lowlevel messagebox for X11. It is very limited in use and can be fine tuned when needed.
**SDL/APPLE**
There is no implementation for SDL or APPLE at this moment as the platform support feature targets mostly Windows users.

This reverts commit 44d042094e and adds a
simpler workaround for just the node links display issue. There are other
issues though so this is not a full workaround.
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.

There was an workaround implemented for specific the Intel HD Graphics
4000 GPU on Windows platform. Other GPU from the same series also need
this workaround.
We will enable the workaround for specific drivers.

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.

The shaders are: `GPU_SHADER_3D_FLAT_SELECT_ID` and `GPU_SHADER_3D_UNIFORM_SELECT_ID`.
This commit allows the drawing of the mesh select ids to be done on a 32UI format texture.
This simplifies the shader that previously acted on the backbuffer and had to do an uint to rgba conversion.

Some old AMD drivers crash when a vbo with stride 1 is used a few times.
I have not found a real solution to this problem. So the solution was to use a vbo with stride 4 (which in theory is less efficient and takes up more memory space).
BF-admins agree to remove header information that isn't useful,
to reduce noise.
