r8233: - added support for more base types in pidl ejs

- added auto generation of a header with prototypes for public ejs functions

- make public functions non-static

- fixed allocation of fixed sized arrays

- added 'noejs' flag indicating that a typedef will be handled manually by ejs

- added manual functions for sid and GUID, so they show up as nice
  strings in ejs scripts

This allows ejs to bring in samr, security, lsa and misc IDL functions
