Depsgraph: Cleanup, remove unused untested functions

Depsgraph: Use dependency graph flush routines to update particle settings

Previously tagging particle settings for update will iterate over all objects and
all their particle system to see whether something needs an update or not. Now we
put ParticleSettings as an ID to the dependency graph, so tagging it for update
will nicely flush updates to all dependent particle systems.

Current downside of this is that due to limitation of flush routines it will cause
some extra particle system re-evaluation when it technically not needed, and what's
more annoying currently it will discard point caches more often.

However, this is a good and simple demonstration case to improve tagging/flushing
system to accommodate for such cases (similar issues happens with CoW and shading
components). So let's try to find some generic solution to the problem!

Depsgraph: Use explicit parameters eval operation code

This replaces usage of generic PLACEHOLDEWR with string lookup with more
explicit opcode. This should make it faster to build dependency graph by
avoiding string comparisons when it's not needed.

There should be no user measurable different.

Depsgraph: Add generic parameters evaluation operation code

Currently unused, but the idea is to use this code instead of placeholder
operation code followed by string comparison.

Depsgraph: Use more explicit naming for operation codes

This way it's better indication what group of operation codes things belongs to.

Despgraph: cleanup, make separation of opcodes strings more clear

Depsgraph: Use more explicit name for particle system evaluation opcode

Fix (unreported) seldom crash when using previews in filebrowser.

Hopefully fix it actually, at least could not reproduce it anymore with
that changen, but Was already quite hard to trigger before.
We need a memory barrier at this allocation, otherwise it might happen
after preview gets added to done queue, so preview could end up being
freed twice, leading to crash.

Manipulators: use nearest manipulator

Add utility function to get the nearest hit

Fix T52116: Blender internal BVH build crash in degenerate cases.

Merge branch 'master' into blender2.8

Fix T52092: Crash un-grouping nodes

Outliner: Use scene_layer from context

Fix T49498: continuous grab issues on macOS, particularly with gaming mouses.

Change the implementation so it no longer takes over the mouse cursor motion
from the OS, instead only move it when warping, similar to Windows and X11.
Probably the reason it was not done this way originally is that you then get
a 500ms delay after warping, but we can use a trick to avoid that and get much
smoother mouse motion than before.

Fix T52109: Folder search won't work when selecting animation output folder.

Text search would not run in case there was no 'type' enabled in filter
buttons. Now instead consider that no types enabled == all types
enabled.

Layer cleanup: get rid of one of the placeholder functions

Context/Workspace: Get scene layer from workspace

Fix bad loss of precision when manually editing values in numbuttons.

While drawing nice 'rounded' values is OK also for 'low precision'
editing like dragging and such, it's quite an issue when you type in a
precise value, validate, edit again the value, and find a rounded
version of it instead of what you typed in!

So now, *only when entering textedit of num buttons*, we always get the highest
reasonable precision for floats (and use exponential notation when
values are too low or too high, to avoid tremendous amounts of zero's).

Eevee: Avoid crash when using dupli objects.

This is waiting a for a better solution.

Eevee: Fix transparency not drawing after volumetrics.

Fix T52089, Fix T52091
