Fix T52663: Remap used invalid local-view data

Only the camera from View3D.localvd is used,
other pointers may be invalid.

Longer term we should probably clear these to ensure no accidents.
For now just follow the rest of Blender's code and don't access.

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.

Fix T52650:Grease pencil selection its not automatically updating in Clip Editor

Fix T52678: Crash editing gpencil w/ frame-lock

Fix leak w/ ocio glsl draw

Fix leak caused by wrong ownership flag

Fix T52046: View transform applied twice w/ GL render

Patch from @sergey w/ minor edit.

Merge branch 'master' into blender2.8

Correct function name in argument parsing

PyAPI: use bl_rna_get_subclass for node API

Returns a default value instead of an error when the type isn't defined.

PyAPI: add function to get an RNA subclass

This is inconvenient in regular Python, add a class-method
to perform the operation, eg:

bpy.types.Node.bl_rna_find_subclass("CustomNodeType")

Cleanup: remove goto's

UI: fix memory leak when copy-to-selected failed

Merge branch 'blender2.8' into greasepencil-object

Merge branch 'master' into blender2.8

This discards node drawing changes which need to be written as shaders.

Merge branch 'master' into blender2.8

Weight Smooth: remove source option

Use current selection mode instead of an operator option.

Fix T52639: Weight paint smooth tool crash

Workaround node types not being exposed

We might want to have a utility function for this,
for now just keep it working.

Cleanup: custom nodes template

- Use conventional (pep8) prop names
- Simplify class registration
