Cleanup: right shift in interface code

Keymap: add generally useful popups to F-Keys 1..4

This allows key bindings: link/append and user-preferences
to be accessed via keys - without having to assign keys to each action.

- F1: Context sensitive help.
- F2: File Context Menu.
- F3: Search.
- F4: Window Context Menu.

Other keys F5..10, remain free,
ideally they can be kept for user actions.

Fix T55687: compile error when not using c++11.

Fix T55626, fix T55106: Cycles motion blur + persistent images bug.

Merge branch 'master' into blender2.8

RNA: use bool for boolean RNA types

We were using int's for bool arguments in BKE,
just to avoid having wrapper functions.

Cleanup of fix_normal_shading
Fixed the edge crease that was present and also made significant
performance improvements.

Cleanup: reduce variable scope

Cleanup: avoid calloc when immediately overwritten

Cleanup: remove num argument prefix

Cleanup: RNA naming

Cleanup: use '_len' suffix for line stipple

3D View: use 3px dashed relationship line

Seems this was accidentally doubled from 2.7x?

Revert "Experimental Tweak: Only show relationship lines between objects when either the parent/child object is selected"

This reverts commit 912931964723cb69dafd4adebe3daf093e3e78c1.

This meant users needed to select everything to see relationship lines,
this isn't always easy since objects can have limit-selection set.

This could be made into an enum option if it's important.

UI: set default theme outline alpha

The outline wasn't being set causing it not to draw.

Cleanup: use f-string

UI: support check-boxes in quick menu

Could support other RNA types,
however menus don't work well in this case.

Cleanup: split out context member query
