Cleanup: spelling, change breaked to braked

Cleanup: unused warning

Shading: Refactor Math node and use dynamic inputs.

- Implement dynamic inputs. The second input is now unavailable in single
operand math operators.
- Reimplemenet the clamp option using graph expansion for Cycles.
- Clean up code and unify naming between Blender and Cycles.
- Remove unused code.

Industry Compat Keymap: support new outliner features

Adds support for changes in the outliner from the soc-2019-outliner
branch. All changes made in the default keymap are made in the
Industry Compatible keymap, except for renaming. Renaming is done
with Return in the Industry Compatible keymap.

Fix: Outliner gsoc versioning

Move outliner versioning for syncing and themes to the block
for the next subversion bump. It was not moved from the first
location it was placed in the soc-2019-outliner branch.

Old files will now load with synced selection enabled reliably.

Fix T68782: false occlusion in selecting vertices and edges with objects in any wire view

Cleanup: spelling

Cleanup: correct comments

Fix T68760: "Reload Scripts" '_sys_path_ensure' missing

Missed this in recent update.

DRW: Fix couple of issues in DRW_draw_select_id

Theses 2 function calls are mandatory.

Fix T68723: GPencil - Split Select mode for Sculpt and Edit mode

Actually, the selection mode is not visible in Sculpt mode when mask is enabled, but still is used.
Also, the mode is shared between Edit mode and Sculpt mode and for meshes the selector is by mode.

This commit splits the select mode in different properties and show the selector in Sculpt mode to define the Select mode. Also, the Select Mask button has been removed and now the Select Mode buttons work equal to Meshes where the select buttons are the mask enable too.

Fixed some old code not valid detected during these changes.

Fix T68722: Improve Smooth algorithm for Thickness and Strength

Now the GPencil smooth algorithm uses a average value instead to use only two points and the interpolated value.

Fix unreported GPencil Thickness modifier affecting strokes not in Vertex Groups

Prior to this commit: If the Grease Pencil Thickness modifier is set to Normalize and a Vertex Group is selected, the thickness of all strokes are effected when changing the Thickness parameter. Points on strokes are only normalised (= pressure set to 1.0) if they are part of the Vertex Group; the strokes themselves may still change thickness.

With this patch: If Normalize is selected with a Vertex Group, Blender now pre-checks each stroke to determine whether it has vertices within or outside the Vertex Group. If all the points on the stroke belong to the Vertex Group, it normalises the whole stroke to a uniform thickness. If some or none of the points of the stroke belong to the Vertex Group, the stroke is now left as is.

Fix T68753: GPencil tooltip typo

PyRNA: include class name in double-register exception

Helps debugging errors when classes are registered twice.

Outliner: Allow select on row icons

Allow selection of subtree elements on a collapsed element's
row. Because subtree elements are aggregated by type, a select on
an icon that represents multiple subtree elements will invoke a
popup menu to select the specific subtree element.

Also draws highlights on cursor hover over a row icon.

Any child elements that are linked to multiple collections will
only be listed in the popup one time, and selection from the
popup will select the first instance in the subtree.

Outliner: invisible object filter

Adds an invisible object filter in the outliner to show hidden
objects. This is useful to quickly locate hidden items in a large outliner
tree and easily toggle visibilty back on. Invisible refers to an object
being hidden, or viewport visibility restricted.

Outliner: walk navigation operator and openclose fixes

Adds a keyboard walk navigation and selection operator to the
outliner. Up and down arrow keys walk up and down the list of
elements, and left and right will open and close elements if
the elements are closed or opened respectively. Holding shift
while walking up and down the tree expands the selection.

Holding shift while clicking or pressing left and right arrows
will expand or collapse all children elements recursively.
Pressing enter to openclose the hovered element is removed.

Also allows click+drag for openclose of element subtrees.

This moves openclose toggling to the openclose operator to
remove duplicate code. The outliner tree building is tweaked
slightly to set the proper parents in scene display mode for walk
select to walk to parents without errors.

Outliner: Use F2 to rename active outliner item

Previously with F2 mapped to the global rename active object
operator, it was not posible to use the conventional F2 to rename any
outliner element like collections or object data. This adds F2 to the
outliner keymap to call the outliner rename operator rather than the
popup rename object operator.

Outliner: Draw sequencer and vertex group icons

Draw icons for sequencer and vertex groups. The sequence
types need updates because they all draw in various colors
and some sequence types do not have an icon.
