Fix off-by-one in hostent/servent pointer list terminator
The h_addr_list/h_aliases/s_aliases copy loops in deepCopyHostent() and
deepCopyServent() reserve N pointer slots for N entries and then write
the terminator with *++q, one slot too far, so the array isn't
terminated right after the last entry and that slot holds copied
address/alias bytes used as a pointer.
Reserve a slot for the terminator and write it with *q.
