Moved src/ source code to src/qpid directory:

 - allows rhm package to build consistently against checked-out or installed qpid. 
 - consistent correspondence between source paths and C++ namespaces.
 - consistent use of #include <qpid/foo> in source and by users.
 - allows header files to split over multiple directories,
   e.g. separating generated code, separating public API from private files.
