Enable MultiEdit keys in Sculpt/Weight Paint modes

The Q and Shift+Q keys can be used in Sculpt and Weight Paint modes too, and not only in Edit mode.

Enable Multiedit in Weight Paint mode

PyAPI: fix rna_info for changes in type access

PyDoc: update context_type_map

RNA/PyAPI: Expose Py classes in bpy.types

Operators and their properties are two different types

Previously both operators and their properties are added
causing C operators to access the properties, Python the classes.

Favor consistency in this case so only Python classes are added.

Cleanup: avoid confusing assignment

various smaller fixes / cleanup for obstacles and guiding

T52534: Compositor artifacts when scaling

Increased the maxx and maxy area of interest when scaling in this case.

Fix T52634: EditMesh Remove doubles could hang

A single diagonal axis was used for sorting coordinates,
the algorithm relied on users not having vertices axis aligned.

Use BLI_kdtree to remove doubles instead.

Overall speed varies, it's more predictable than the previous method.
Some typical tests gave speedup of ~1.4x - 1.7x.

BLI_kdtree: utility function to remove doubles

Cleanup: Replace int text to double quotes

Merge branch 'blender2.8' into greasepencil-object

CMake: use Blender's glew by default

Use since it's always bundled to avoid any issues caused
by version mis-match.

Fix: Deleting GPencil keyframes in DopeSheet didn't redraw the view

Fix: Border select for GPencil keyframes was including those in the "datablock" channels even though those weren't visible

This meant that it was easy to accidentally select too many keyframes

Fix: GPencil Sequence Interpolation for thickness/strength was inverted

For example, if you have two keyframes:
k1 = 1px, k2 = 10px

it was doing:
1px, 9px, 8px, ..., 3px, 2px, 10px
instead of:
1px, 2px, 3px, ..., 8px, 9px, 10px

Fix T52227: Time Slide tool doesn't take NLA mapping into account

improved initial velocity setup for smoke and liquids

initial velocity grids now only allocated if actually enabled in UI. rudimentary support for liquid initial velocity when using plane inflow objects, proper liquid initial velocities (set invels in full volume) still todo though.

[deps/msvc] Debug flags for optimized debug libs were inverted for cxx.
