UI: group sculpt brushes in the toolbar

All sculpt brushes are accessible from the toolbar, grouped by type
to keep the toolbar a fixed size.

UI: fix toolbar groups w/ data_blocks

UI: hide sculpt panels from toolbar

These are already available from the topbar.

Cleanup: warning, use STRNCPY macro

UI: initial dynamically generated sculpt tools

Lots more work needed, this just lists sculpt tools in the toolbar.

Tool System: support data-blocks in tools

Needed so tools can set the active brush.

UI: support tool generators (no visible change)

This allows toolbar definitions to dynamically generate tools,
needed for generating a tool list from brushes for eg.

3D View: add initial view.shading and view.overlay in RNA.

These are mostly empty still, many properties need to be renamed and moved there.

Cycles: Cleanup: Remove double semicolons

3D View: move shading and overlay settings into popovers.

* This is just moving buttons to get a bit closer to the intended design,
better naming and layout is needed.
* Popovers currently work best when the 3D view header is at the top, with
the most important settings nearest to the mouse. Open design question is
if we should flip (part of) the buttons if header is at the bottom.
* Another question is if selecintg a shading mode enum should immediately
close the popover since those are changed often, unlike the other settings
for which it seems more convenient to keep the popover open.

UI: auto open adjacent pulldown and popover buttons.

UI: don't flip contents of popovers, avoid closing when size changes.

Fix use of removed Blender Internal properties.

UI: show popover arrow directly under the button

A visual hint but looks broken when its not pointing to the button.

UI: fix toolbar not snapping properly with system DPI and display scale.

Python/UI: add more convenient API for drawing based on DPI.

system.ui_scale: size multiplier to use when drawing custom UI elements.
system.ui_line_width: suggested line thickness and point size in pixels.

Edit Mesh: loop-cut multi-object support

UI: Number Slider - treat percentage as a special case

This is to address things like a percentage slider with a fixed soft mininum.

For example, the render resolution ranges from 1% to 100% and it is really
strange to have the slider showing nothing filled when the ui shows 1%.

UI: Number slider uniform filling

Now we always fill the slider with a vertical boundary. A bit hard to explain,
but very easy to see the difference.

I split the widget in three parts and used fragment shader discard to remove the
undesired bits. That means all the widget program is doing a bit extra
calculation.

UI: Remove hardcoded 11 uniform parameters

Using a define makes it easy to increase this later.
