unlike other functions called from the config parser code,
anonymous_insert() accesses the global config variable rather than
passing it as an argument. however the global variable is only set
after successful loading of the entire config.
we fix this by adding a conf argument to each anonymous_* function,
passing the global pointer in calls done from outside the config
parser.
