GLSL: rename edit_overlay -> edit_mesh_overlay

Avoid confusion with overlays with non-mesh types

Use 'safe' macros for common free operation

Same as MEM_SAFE_FREE macro,
checks for NULL, runs free then sets NULL.

Blocks of code that do this many times are noisy and likely
errors here wouldn't be noticed immediately.

Also NULL's static vars which were being left set.

Cycles Denoising: CPUDevice tweaks from the review

Cycles Denoising: Add back the feature strength option

Note: The control is now different, reusing old values might give surprising results

Move BKE_pbvh_get_num_nodes out of node-access functions

Also use regular return

Merge branch 'master' into soc-2016-pbvh-painting

Fix manipulator interaction not using correct projection matrix

Moved matrix setup for interaction into own util function now. Also did
cleanup in related code.

Force using HMD parameters instead of camera ones in camera perspective

Fix lens separation applied wrongly onto projection matrix

fix drawing file column dividers (T51189)

Problem was an edge case where vertex_ct logic and draw logic disagreed on how many dividers to draw.

Fix: copy draw logic to earlier vertex_ct

I also skip any drawing or setup if vertex_ct = 0, and set color attribute only for each line's provoking vertex. Small optimizations but these things add up.

Add new data_size new parameter and avoid error with null gp

Fix projection matrices not taking focal length of HMD into account

Merge branch 'blender2.8' into greasepencil-object

Fix T51188 compilation errors in Windows

Rename Smudge to Smear since we already call this smear in image editor

Merge branch 'master' into soc-2016-pbvh-painting

Task scheduler: Prevent race condition for the pools created from non-main thread

We can not re-use anything for such pools, because we will know nothing about whether
the main thread is sleeping or not. So we identify such threads as 0, but we don't
use main thread's TLS.

This fixes dead-locks and crashes reported by Luca when doing playblasts.

Re calibrated the vertical position for the Vive lens distortion shader

Fix crash when use_group_restrict is disabled

Move SculptBrushTest initialization out of loop

There is no need to run this every iteration.
