Generate all APIs.
This CL expands the generator to create all the .rsh files, not just
the core_math one. To do so, processing of types (simple, struct, enums)
and constants was added. .spec files corresponding to each .rsh file was
created. Documentation was added.
This CL also generates HTML documentation files. This generation will soon
be upgraded.
To make the code easier to expand, I've done fairly extensive refactoring.
In a subsequent CL, the APIs will be regrouped in different header files to
simplify learning the APIs. In an other, the documentation generation will
be futher improved and incorporated in the actual online help.
Also removes rs_path & related functions.
