Fix for the most disruptive items in QPID-243.

* All #include lines now use '""' rather than '<>' where appropriate.
* #include lines within the qpid project use relative includes so that
  the same path will work in /usr/include when installed as part of the
  client libraries.
* All the source code has now been rearranged to be under src in a directory
  analogous to the namespace of the classes in it.
