BLI_task: add support for listbase parallelized for loops.

Code by @sergey, with small edits and doc by @mont29.

Cleanup: fix inconsitency in dynamicPaint_outputLayerExists()

Dyna WPaint indeed only uses first output layer, but better be consistent in those cases...

Dynapaint: cleanup of BKE code.

Line lengths, monolined 'if' statements, int -> bool, etc.

Also, replaced some internal cooked stuff by BLI helpers (most notably, the
'is inside UV triangle' code in `dynamicPaint_createUVSurface()`), and some
other minor optimizations.

BLI_math: add 'equals_m4m4' (and 'm3' variant) helpers.

Cycles: Scale debug pass with number of samples

This way it's easier to compare different renders together without
worrying about scale too much.

Image editor: Show actual value of single-channel buffer in sample info

Previously if image only had single channel only z buffer value was displaying.
This isn't handy for cases when you've got single channel buffer which is not
a z buffer.

Also fixed possible read past the array.

install_deps: Avoid conflicts on Arch-based systems when gcc-multilib is installed

install_deps can fail due to conflict between gcc (referenced by base-devel) and
gcc-multilib if the latter is installed. This avoids the conflict by filtering
the contents of base-devel when needed.

Cycles: Add support for single channel byte textures.

This way, we also save 3/4th of memory for single channel byte textures (e.g. Bump Maps).

Note: In order for this to work, the texture *must* have 1 channel only.
In Gimp you can e.g. do that via the menu: Image -> Mode -> Grayscale

Fix array bounds compile warning.

Fix T48413: editmesh intersect tool crash

Its important to add tri-edge intersections from both sides.

Correct debug prints

Fix depsgraph tagging during the relations build pass.

Followup commit to 18e5e2fa1ac26ccbbd0cc8b486a5d92be6888021. Needs the same
treatment in the second pass when ID tags are reset again.

BMesh: avoid calling delete operator w/ face dissolve

In nearly all cases this isn't needed.

Fix missing piece in recent rBce65fae8f32c (support for '+' key).

Thanks to Daniel Rivera (Dr2d4) for the headup!

Recent bmesh face-join caused regression (T48407)

Cleanup: Fix typo.

Armature outline drawing used single width line

Only set line width in pose-mode

BMesh: use active face fallback w/ select-path

From user perspective, last selected face is the same as the active face,
use this as a fallback.

Cleanup: Remove outdated comment and add new one about slot IDs.

BMesh: ignore non-manifold face connections

Was showing an error message,
now dissolve the faces that and delimit at non-manifold boundaries.
