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.
