Mantaflow: Fix for versioning issue

Fixes crash with old fluid (Elbeem) modifier

Mantaflow: Fix for noise density issue

Emission values for noise need to be upscaled with upres factor

reorganize where interfaces are declared

remove unused parameter

don't pass particle allocator using BlockStepData

use annotation for properties

remove ParticleSet and ParticleSets abstraction

Fix possible crash when opening files saved with new file browser open

EEVEE: Remove softness parameters from RNA & UI

Keep it in DNA for backward compatibility

EEVEE: Fix sunlight when sun angle is 180 degrees

EEVEE: Shadow: Add back shadow bias

This is needed in some corner case (shadow acne due to aliasing and depth
disparity). This is a simple bias added to default bias. It should not be
needed most of the time but we leave it at 1 by default.

EEVEE: Fix spotlight shadow optimization

Spot light can be non-uniform and scale in one direction. This fix makes
sure both directions are taken into account before skipping cubemap faces.

UI: Make cascaded shadowmap panel on top of contact shadow

This make more sense as cascade parameters are more important.

EEVEE: Shadow: Add temporal sampling to shadowmaps

If soft shadows is enabled, we randomize the shadowmap sample position
to reduce aliasing artifacts (jagged edge shadows).

Cleanup: EEVEE: Split eevee_lights.c into smaller files

Also have some const correctness fix and some header cleanup.

Eevee: Shadow: Refactor / Cleanup of shadow update

- Replace EEVEE_lightbits by BLI_bitmap
- Replace EEVEE_BoundSphere by BoundSphere
- Support for dupli light shadows
- Detect unecessary update of soft shadows (i.e: moving the view)
- Remove Object references

Eevee: Light: Refactor shadow tagging to allow dupli shadow casters

Dupli objects can now cast shadows.

This also replace the custom lightbits by BLI_bitmap.

Eevee: Shadows: Add texel border on shadow cube for better edge filtering

Unfortunately, this seems to be imprecise on lower cube resolution. But
the result is still most of the time more pleasant than no border filtering.

Eevee: Shadow: Speedup: Only render shadow cube face needed

This reduce the number of face to render to 5 in the case of area lights
and 5 or 1 for spotlights.

Spotlights that have a spot size less than 90 degrees only need 1 face and
are the fastest.

Eevee: Shadows: Make shadowmap follow light orientation

This is in preparation of an optimization
