Altered ipcacheParse so that it returned -1 for *all* errors, 0 for 'no
data yet', and N for data.

Changed dummy_handler which did nothing to ipcacheHandleCnameRecurse which
accepts the cbdata parameter as either an generic_cbdata(ipcache_entry) or
null. On NULL it behaves as dummy_handler used to.
With data it adds the DNS addrs found from the subquery to the entry
passed in as parent. Then calls the parents callback instead.

The single function, (name just slips my mind), which calls ipcacheParse
altered to handle the new return cases and NOT add the entry to the live
cache or call its callback IFF 0 received. Thus waiting until the child
call returns.
