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. git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk@524769 13f79535-47bb-0310-9956-ffa450edef68
