Manipulator: Fix arrow2d drawing outside hotspot

Buildbot: Fix paths to sndfile and flac

Need this in 2.79 branch as well, since build rules are based on this files.

Manipulator: missing exit() call

Manipulator: cage2d initial rotation support

Fix T52433: Volume Absorption color tint

Need to exit the volume stack when shadow ray laves the medium.

Thanks Brecht for review and help in troubleshooting!

Merge branch 'master' into blender2.8

Cleanup: use const

Also use assert w/ rotate_m4.

Cycles: Cleanup, style

Fix T52649: missing custom (split) normals from FBX exporter.

Own mistake in recent rB25c5928b2b6 (this DOES NOT affect 2.79 release).

Fix T52531: Blender 2D stabilisation node issue when autoscale is selected

Threading conflict, should be safe for 2.79.

PyAPI: Add bpy.utils.register_classes_factory

Avoids having boiler plate register/unregister functions.

Fix T52522: VSE renders with alpha transparent PNG image incorrectly

Need some extra checks and should be probably end up in 2.79 since that's a regression.

Cycles: Fix compilation warning

Fix T52533: Blender shuts down when rendering duplicated smoke domain

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

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.
