Charybdis currently leaks about 45-50k per configuration parse, including every rehash. This change plugs these leaks by properly iterating through all conf_parm_t structures to seek all strings that should be freed and also by freeing the conf_parm_t structures themselves. These leaks have been present since the original rewrite of the configuration parsing system in ircd-ratbox r11953. Additionally, this change also cleans up and documents the parsing code a bit.
