Disable strict XML documentation config checking; fix crash caused by sorcery

This patch does two things:
 1. It disables (temporarily) strict XML documentation checking for module
    configurations. We should re-enable it before making any release from
    trunk.
 2. Pass the module flag AST_MODULE through sorcery. This means several of the
    API calls are now macros and will do this automatically for you. The config
    framework needs the module that objects are registering to so it can
    properly construct the documentation. (This was already a required field,
    but sorcery was getting by without it)
