reorganized code generation

- source file includes generated header only,
  generated header includes anything else
	and is able to prepend include statements
	to files that need to be included *before*
	any php delivered header files
- 'private' functions are now moved up in the
  generated source file so we do not add extra
	C protos for them before use
