 python-qpid-proton setup script

 DISCLAIMER: This script took lots of inspirations from PyZMQ, which is licensed
 under the 'MODIFIED BSD LICENSE'.

 Although inspired by the work in PyZMQ, this script and the modules it depends
 on were largely simplified to meet the requirements of the library.

 The behavior of this script is to build the registered `_cproton` extension
 using the installed Qpid Proton C library and header files. If the library and
 headers are not installed, or the installed version does not match the version
 of these python bindings, then the script will attempt to build the extension
 using the Proton C sources included in the python source distribution package.

 While the above removes the need of *always* having Qpid Proton C development
 files installed, it does not solve the need of having `swig` and the libraries
 qpid-proton requires installed to make this setup work.

 From the Python side, this scripts overrides 1 command - build_ext - and it adds a
 new one. The latter - Configure - is called from the former to setup/discover what's
 in the system. The rest of the commands and steps are done normally without any kind
 of monkey patching.
