Memory: add MEM_malloc_arrayN() function to protect against overflow.

Fix T53810: Crash removing a scene used in render

Header drawing accesses the scene too.

corrected some more special constraint breaking activation behavior (was activating too much)

Revert "Fix T53752: Draw curve fails w/ stylus"

This reverts commit d0e0f33f57b02fecf75c08f3c144d07915367781.

Requested by author, since it raised new issues, better not have it in
bugfix release!

small transform fix for animated mesh binding

some corrective changes in special breaking activation behavior

put animated mesh settings to new panel, some fixes

Fix T53772: Presets don't support colons

fix for binding, should leave no shards behind now

Fix T47212: Luminance Key not working with HDR and out-of-gamut ranges.

Differential Revision: https://developer.blender.org/D2981

Fix T53567: Negative pixel values causing artifacts with denoising

Now negative color values are clamped to zero before the actual denoising.

Cycles: Fixed compilation of CUDA kernels. Follow-up fix for my last commit.

Cycles: Workaround for performance loss with the CUDA 9.0 SDK.

CUDA 9.0.176 apparently caused some slow down on high-end Pascal cards that can be mitigated by increasing the number of registers. See https://developer.blender.org/F1142667 for a detailed comparison.

Fix T53692: OpenCL multi GPU rendering not using all GPUs.

Ensure each OpenCL device has a unique ID even if the hardware ID is not
unique for some reason.

Fix T53755: Cycles OpenCL lamp shaders have incorrect normal.

fixes for bind animated mesh: transform and jump issues

experimental bind of animated vertices (other object) to shards

this transfers vertex motion during simulation and allows some kind of "deformation" of the fractured mesh, without
refracturing it

Cleanup: SGI format, avoid overflow

Harmless but causes warnings

Cleanup: SGI format, use uint/short/char types

Fix SGI foramt reader CVE-2017-2901

Integer Overflow Code Execution Vulnerability.

Reader no longer crashes on corrupt images (from own fuzz testing).
