Log Message:	- First pass at s_conf.c cleanup for attach clients - attach_conf() is gone replaced with attach_iline() Clients/servers have one single I line "attached", i.e. the confs list is gone. - Add attach_leaf_hub() Add a leaf or hub mask to the given server, ->serv must exist since there can be a list of hub masks and leaf masks, this continues to be a dlink list - Removed redundant find_conf_exact() This function can be replaced in all cases with find_exact_name_conf() notably because all find_conf_exact did differently was count whether an oper conf would cause an already connected client to exceed class limits. - oper_up() now takes an extra conf pointer pointing to the found oper conf, the oper flags are set in the client->iline as necessary in oper_up() - Cleaned up more prototypes that should have been moved from s_conf.h to parse_aline.h notably. find_kill() and find_gkill() - m_stats.c needs more cleanup since memory in attached "confs" is now not counted. This should be replaced with iline memory count and hub/leaf confs memory count.
