crash fix for deleting connected objects before its connectors

crash fix for FM objects being copied after connect

Cycles: tweak CUDA messages and avoid build errors with existing sm_2x configs.

Code cleanup: remove some more unused code after recent CUDA changes.

rigidbody sort fix for external constraints

Cycles: Remove Fermi texture code.

This should be the last Fermi removal commit, unless I missed something.
It's been a pleasure Fermi!

Cycles: Remove fermi related defines from the code.

Did not touch Texture related defines, that comes next.

Cycles: Remove Fermi support from CMake and update runtime checks in device_cuda.cpp.

Fermi code in Cycles kernel and texture system are coming next.

Merge branch 'blender2.8' into greasepencil-object

Buildbot: Disable Cycles CUDA support on 32bit, and stop building sm_2x.

Code cleanup: remove WM subwindows.

These no longer made much sense after regions were added, they just
duplicated state that was already in the regions.

Fix GL_FRAMEBUFFER_UNSUPPORTED warning in console on macOS.

crash fix for external constraints

ensure refresh of "parent" FM object on every refresh of connected objects, also ensure evaluation order in rigidbody.c / bullet (parent always after children)

Merge branch 'master' into blender2.8

DRW: Fix assert with DRW_shgroup_material_instance_create.

Fix T53399: Dopesheet keyframes and the drawing of points were not visible with some Intel cards

GHOST: Windows: Print information on the GPU

Fix UV scale for stroke endcaps

Fix UV coordinates for strokes

Use DRW function to check opengl render

Instead of check global value, use draw manager function to verify if it's running an opengl render.
