config.c: pass ctx in configsets

Pass config_context to config callbacks in configset_iter(), trivially
setting the .kvi member to the cached key_value_info. Then, in config
callbacks that are only used with configsets, use the .kvi member to
replace calls to current_config_*(), and delete current_config_line()
because it has no remaining callers.

This leaves builtin/config.c and config.c as the only remaining users of
current_config_*().
