Cleanup: style, use braces for editor/curve

Depsgraph: Standardize parameters nodes

Makes it possible to handle them the same from drivers
relations builder.

Solves missing operations errors printed when opening
autumn character.

3D View: move deselect all logic into an option

This removes `VIEW3D_OT_select_or_deselect_all`, adding a
deselect_all option to the `VIEW3D_OT_select` operator.

- Add utility functions to simplify de-selecting all.

- Return true from selection functions when they change the selection
to avoid redundant updates.

- Use arrays of bases when passing objects between selection utility
functions since some users require bases.

- Fix logical error in box selection that updated all objects after
the first hit.

Fix use of uninitialized variable in grease pencil materials.

Fix T62946: function abs() not working in driver expressions.

Fix T62946: missing warning when Python driver expression execution is disabled.

Cleanup: remove unused function

Cleanup: style

Cleanup: warnings, correct assert

Fix T62927: Assert when opening default 2.79 startup file in 2.80.

Not sure why that was asserted on instead of handling the flag properly,
if base is not selectable, then just do not select it...

Have the feeling this code handling sync of flags between bases and
objects could use some cleanup, but that will be for another day.

Fix T62856 Toon BSDF and viewport/UI oddities

This was caused by the material not tagged to use Diffuse lighting data.

GPU: State: Replace GL_BLEND by GPU_blend

GPencil: Remove unused var

Fix T62930 Eevee: Wireframe input node not working with certain compiler

GPencil: Only brushes with pinned materials have materials

Using GP_BRUSH_MATERIAL_PINNED to switch between active material and brush material, instead of updating all brushes on active material changes. This will allow brushes to have no material and therefore to not inflate the user count.

This fix T62465.

Fix T62865: Make Single User after Objects to Scene must be done twice.

Selected status was not properly moved from new object to new created base.
This prevented next steps (making obdata, materials etc. local) to ever
