Writing .fc files without any mistake is quite hard. Sometimes a regular
expression pattern compiles fine but it does not match what is intended.
Add a script that detects some issues in .fc files. When this script is
used directly ("./testing/check_fc_files.py"), it checks the content of
policy/. The path to policy/ can also be provided by option -p.

PyXML has not been required to build the policy and its documentation
since at least Python 2.6, which comes with an "xml" module.
Moreover, some support scripts requires Python 2.6 or above (and are
compatible with Python 3.4, maybe also with other versions of Python 3).
Add the minimum supported version of Python in INSTALL.
