Merged changes in the trunk up to revision 41768.

Conflicts resolved:
source/blender/makesdna/intern/makesdna.c
source/blender/makesrna/RNA_enum_types.h
source/blender/render/intern/source/shadeinput.c
source/blenderplayer/bad_level_call_stubs/stubs.c

Additional changes:

* source/blender/makesrna/intern/rna_linestyle.c: Fixed white
space issues that generated a number of compiler errors.  The
problem was that two string literals for enumerating MA_RAMP_SOFT
and MA_RAMP_LINEAR contained a space.  The string literals are
supposed to represent a valid C identifier because of their use
for automatic code generation.

* Stroke transparency has been temporarily disabled due to a
functionality conflict with some merged changes.  A fix of this
issue is planned.
