Modifiers: Armature DerivedMesh ? Mesh

The mesh parameter of armature_deform_verts() is now const, to indicate
that it's safe to pass ob->data to it directly.

Modifiers: Simple Deform & Build, DerivedMesh ? Mesh

This commit introduces `EditMeshData`. The fields in this struct are
extracted from `EditDerivedBMesh` into their own struct `EditMeshData`,
which can then also be used by the `Mesh` struct. This allows passing
deformed vertices efficiently to the draw routines.

The modifier code constructs a new Mesh instead of writing to ob->data;
even when ob->data is a CoW copy, it can still be used by different
objects and thus shouldn't be modified by a modifier.

Modifiers: Add wrapper functions with Mesh / DerivedMesh conversion

Makes the follow changes:

- Add new `deform*` and `apply*` function pointers to `ModifierTypeInfo` that take `Mesh`, and rename the old functions to indicate that they take `DerivedMesh`. These new functions are currently set to `NULL` for all modifiers.
- Add wrapper `modifier_deform*` and `modifier_apply*` functions in two variants: one that works with `Mesh` and the other which works with `DerivedMesh` that is named with `*_DM_depercated`. These functions check which type of data the modifier supports and converts if necessary
- Update the rest of Blender to be aware and make use of these new functions

The goal of these changes is to make it possible to port to using `Mesh` incrementally without ever needing to enter into a state where modifiers don't work. After everything has been ported over the old functions and wrappers could be removed.

Typo fix

Added note about potential crash in add_orco_dm()

Eevee: Fix crash when using visibility groups with dupli objects.

Eevee: Contact Shadows: Add slope based bias & fix brightening.

Eevee: Fix raytracing.

- Fix the confusing naming in raycast()
- Fix raytrace acne caused by the rays not being correctly centered on
the texel.

Fix: Silence |RNA_boolean_get: WM_OT_save_as_mainfile.exit not found." warning on exit

The operator in question doesn't define this property.
I'm commenting out for now in case another operator actually still uses it.

Fix previous commit, sorry about that :/

Static override: rename highly confusing var name in apply code.

We use 'reference' to designate the linked ID which is being overridden
by the local one, so using 'reference' to designate the stored local ID
in apply RNA code was... not a good idea. ;)

Icons: updated icons from @billreynish

This adds vertex paint & sculpt icons + other minor changes.

Merge branch 'blender2.8' of git.blender.org:blender into blender2.8

Overlay: Enabled wireframe drawing for vertex/weight paint

This is a temp hack, so that billrey can use blender 2.8 for
drawing the icons. Hack will be phased out by T54910

Fix compiler warning: Uninitialised var

Add/finish rna read-only access to actual override rules.

For some reasons did not add operations themselves previously...

Static Override: fix 'search matching override operation' function.

Previous code was waaaayyyy to flacky, returning matches for things that
did not actually have much in common!

Refactoring: bvhutils: Use a function that gets the bvhtree through an identifier type.

UI: expose radial gradient as option

Was a separate tool, use option so we can extend more easily.
