Fix T44040: Blender crashes when nodes are muted

It was actually an old issue with wrong conversion happening for muted
nodes, which wasn't visible before memory optimization commit.

This is to be backported to the final release.

Cleanup

Transform: Shift for precision PET adjustment

Patch T36753 by @hjaarnio

Armature Symmetrize tool

D1147 by @julien, with fixes/improvements

Duplicate bones where needed, otherwise use existing.
Keeps parent relations intact, can operate on parts of an armature.

Fix out-of-bounds read BKE_deform_flip_side_name

Cleanup: style (armature duplicate)

CMake: unbundle eigen3

Optionally use systems eigen3 library.

T41989 by @hasufell with edits

CMake: exclude Colamd when OpenNL's disabled

Freestyle: pass Main struct to new/copy

Cleanup: spelling grey -> gray

Revert part of recent color-management commit

This adds back rgb_to_grayscale,
not all color is managed or depends on the current loaded blend file's CM options.

Noted in comments that this is only to be used outside the CM pipeline.

Color managed luminance for shader ramp-in-energy

Cleanup: better not pass function call to FTOCHAR

also use rgb_uchar_to_float

Use fabsf for floats

Select nth option to skip steps

Patch T43752 @codemanx, added matching curve option.

Fix for crash adding mask modifier

Simplify math in mix_linear glsl function. Thanks to valentin for
pointing out on irc.

Fix T44029 textures disappear in viewport if GPU mipmap generation is
off.

GPUs need a full tree of mipmaps up to dimension 1xn to work. This will
make it so for all imbufs but cost is negligible and it's unlikely that
something could break due to that.

Fix bad memory access freeing viewport which uses movie clip

Support UV island selection in UV synch and face select mode.

Enough said, people wanted this for ages, enjoy!
