Tamito Kajiyama 62cede96d3 A major code update for making the DNA file specification of Freestyle settings 
and RNA for it independent of the build flag for enabling Freestyle.  Suggested
by Sergey Sharybin through a code review of the branch.

* Many #ifdef WITH_FREESTYLE blocks were removed to always have Freestyle-specific
DNA file specification and RNA for it built in Blender.  This will allow Freestyle
setting survive even when a non-Freestyle build is used for loading and saving
files.  It is noted that operations are still conditionally built through #ifdef
WITH_FREESTYLE blocks.

* To this end, new blenkernel files BKE_freestyle.h and intern/freestyle.c have
been added.  All API functions in FRS_freestyle_config.h as well as some of those
in FRS_freestyle.h were moved to the new files.  Now the relocated API functions
have BKE_ prefix instead of FRS_.
