Mikktspace: Speed up the merging of identical vertices

Previously, Mikktspace just bucketed the vertices based on one spatial coordinate and then ran full pairwise comparisons inside each bucket.
However, since models are three-dimensional, the bucketing has a massive false-positive rate, and since pairwise comparison is O(n^2), the merging process is very slow.

But, since we only care about exactly identical vertices, there is a much more efficient approach - we can just hash all values belonging to each vertex and form buckets based on the hash.
Since the hash has 32 bits and considers all values, false-positives are very unlikely - and since both hashing and the radixsort that's used for bucketing are O(n), both asymptotical and
real-world performance (as well as code complexity) are significantly improved.

Depsgraph: Fix assert/crash when transforming from redo system

Redo system will set depsgraph to NULL, so need to ensure it exists.

Reported by Julian in IRC, thanks!

Cycles: Add per-tile render time debug pass

Reviewers: sergey, brecht

Differential Revision: https://developer.blender.org/D2920

Cycles: Add Volume Direct and Volume Indirect passes for volume-scattered light

No color pass because it's hard to define what to use as color in a volume.

Cycles: Refactor PassType from bitflag to index in order to allow for more passes

Merge branch 'master' into blender2.8

Depsgraph: Add missing checks from previous commit

Merge branch 'master' into blender2.8

Depsgraph: Don't make non-dynamic hair dependent on time

This way hair system used for static forest does not make playblack slow.

A bit dangerous, but let's see how far we can go!

Fix UV Projection Center Calculation

UV project mixed up global/local space,
3D cursor offset didn't take object scale into account.

Minor improvements:

- Match Cube Project 'center' behavior w/ sphere & cylinder.
- Add active-element center.
- Wrap UV's in Cube Project based on center instead of first vertex.

Cleanup: warnings

Fix error when compiling with msvc

'function': incompatible types - from 'int *' to 'short *'

Eevee: SSS: Add cubic profile for the sake of completeness.

It wasnt really hard except from the wierd sharpness 0.5 multiplication.

Eevee: SSS: Add SSS to the principled shader.

Eevee: SSS: Add Christensen-Burley diffusion profile.

This seems to be a correct implementation of the same diffusion profile as Cycles uses by default.

There are a few bias though:
- We consider _A_ the albedo to be 1 when evaluating _s_.
- We use a factor of 0.6 when computing _d_ to match more or less cycles results.

Note that doing per pixel jittering does bias the result even further (loss of energy).

Fix T51210: Draw Manager: Support for Metaball Drawing

Merge branch 'master' into blender2.8

BLI listbase: add bytes finding helpers.

Quite similar to string ones actually, except more generic. Used in
id_override_static branch currently.

Cycles: Fix crash with split branched path tracing

ShaderData memory was getting clobbered in the branched path code paths.

Was caused by 087331c495b04ebd37903c0dc0e46262354cf026
