#22: orogen: use typelib's source_id tracking to reduce recompilation times

    Type:  enhancement     |      Status:  new                  
Priority:  major           |   Component:  base                 
Keywords:                  |  
---------------------------+------------------------------------------------
 Right now, the following happens:

   * orogen generates a Types.hpp file that includes all the
     headers that are necessary to load *all* types that the
     typekit needs
   * the typekit files include that Types.hpp file
   * the typekit that depend on this typekit also include that
     Types.hpp file

 In practice, it means that if you change a base header, you
 have to recompile *all* typekits from *all* orogen projects
 (more or less)

 The thing is that typelib tracks in which files each types are
 defined. By massaging the XML typelib file  (.tlb) to transform
 absolute paths into paths in the -I path, one could -- in generated
 typekits -- include only the headers that make sense for each
 typekit file. This would most probably not reduce first-compilation
 time, but at least it should dramatically reduce the need for
 recompilation.
