Apply patch (requested by bad in ticket #1887):

src/lib/libc/net/getaddrinfo.c r1.106:
this is supposed to be re-entrant, call don't call __hostalias that uses
a static buffer.

src/lib/libc/net/gethnamaddr.c r1.85:
- don't clobber hp in the RES_USE_INET6 case
- increment naddrs in the yp case
- don't use __hostalias(), it is not thread-safe.

This should finish addressing PR lib/46454
