Depsgraph: Use more const qualifiers

Merge branch 'master' into blender2.8

Added "Delete Invalid Drivers" operator

This operator is available in the graph editor in the Drivers mode, and
allows quick cleanup of drivers marked as 'invalid'.

Cleanup: replace BLI_dynstr w/ BLI_string_joinN

Use in place of recently reverted 'DRW_shader_create_lib'

Depsgrapph: Fix/workaround for missing hair

The issue was happening because dependency graph did not inform particle
settings as modified. This is a regression caused by tagging and flushing
mechanism refactor.

The real fix would be to make particle settings to use ID level recalc flags
rather than own flags, which will also simplify relations around particle system,
and particle settings evaluation.

Revert "Fix use-after free in DRW_shader_create_with_lib"

Caused an error entering edit-mode.

d60f26f37a & 2659500835

Fix assert in mesh batch conversion

Merge branch 'master' into blender2.8

Fix use-after free in DRW_shader_create_with_lib

Limit scope to avoid future accidents

Correct simple deform versioning from D2989

Eevee: Update lightprobes when deleting or linking a new world datablock

Eevee: SSS: Fix OpenGL error when enabling TRANSLUCENCY but not SSSS.

This was causing this error:
"Different sampler types for same sample texture unit in fragment shader"

Fix T53810: Crash removing a scene used in render

Header drawing accesses the scene too.

DRW: Codestyle refactor: Use macro to create shader libs.

This clears up the code from many DynStr usage. Easier to read.

Eevee: SSR: Fix artifacts at object/background limits.

This should have a very small perf impact but it's needed.

Eevee: Fix Hashed Alpha.

Now hashed alpha materials are stable when moving the camera/not using TAA.
It also converge to a noise free image when using TAA. No more numerical imprecision.

There still can be situations with multiple overlapping transparent surfaces that can lead to residual noise.

Eevee: AO: Removes samples and denoise options.

This comes with a lot of code simplification that leads to a small performance improvement.

Eevee: Add macro to sample noise in utilTex.

Avoid future coding error.

Eevee: SSR: Derive the brdf bias from the trace quality.

Also change the range of the trace quality so that the trace actually covers the screen most of the time.

Eevee: Fix SSRefraction noise.
