Fix T56838: Quick smoke failing with Python error.

Again the change to @ operator for matrix multiplication...

Cleanup: Unused variable in release build

Subdiv: CCG, remove redundant call

Gizmo: tweaks to dial drawing

- Add Arc-Inner-Factor, to increase the inner arc radius from 0
(show as a disk).
- When showing an angle value, show the angle-end line thicker
(since thats whats being adjusted).
- Remove offset used by arc drawing which caused aliasing artifacts.

EditMesh: show the spin arc as a thin ribbon

Closer to the design from T54661

EditMesh: orient spin arc to follow the cursor

Gizmo: exclude arc from selection

Also disable polygon smooth before drawing arc.

Gizmo: remove matrix rotation for the dial gizmo

This makes it impossible to rotate the gizmo using the matrix Y axis.

Testing without this and I can't find any cases it breaks.

Correct polygon_smooth being left enabled

Cleanup: comments

Fix unreported: Undo of texts pasted in the Text Editor misses one character.

Caused by commit rB28c34ae7e2d6
Unlike `strncpy`, `BLI_strncpy` ensures the last character is ' '.

Merge branch 'master' into blender2.8

Gizmo: dial3d option to show the final angle

Was showing modal-delta-angle, which isn't useful for the spin tool.

Cleanup: replace pointer/int casts with macros

BLI_utildefines: rename pointer conversion macros

Terms get/set don't make much sense when casting values.

Name macros so the conversion is obvious,
use common prefix for easier completion.

- GET_INT_FROM_POINTER -> POINTER_AS_INT
- SET_INT_IN_POINTER -> POINTER_FROM_INT
- GET_UINT_FROM_POINTER -> POINTER_AS_UINT
- SET_UINT_IN_POINTER -> POINTER_FROM_UINT

Cleanup: trailing space

Merge branch 'master' into blender2.8

Cleanup: replace comment headings w/ doxy groups

Also minor changes:

- Remove unused headers.
- rename SimpleExprParseState -> ExprParseState
- rename max_ops -> ops_count_alloc

Was misleading since maximums are often limits which can't be exceeded.
