PHP binding for Qpid Messaging API

Review Request #462 - Created March 3, 2011 and updated

Paul Colby
A SWIG-based PHP binding for the Qpid Messaging API.

The SWIG-based binding itself is complete, and working (hence needing review).

This diff includes integration with Qpid's autoconf build system.  I've only just begun learning autoconf / automake, so the build integration definitely needs review too :)
