This CL replaces the Doxygen generated documentation by one that's created
by our internal tool found in framework/rs/api. The big advantages:
- Can handle overloaded functions. Doxygen could not and RenderScript has many.
- Can have version information.
- Can match the look of the Java documentation.
- Cleaner look and no leaking of internal paths.
This CL also include changes introduced by the L release which was missing
previously.
