dynamically allocate storage for gethostby* buffers
this change shaves ~1k off libc.so bss size, and also avoids hard errors in the case where the static buffer was not large enough to hold the result. this whole framework is really ugly and might should be replaced or at least heavily overhauled when some changes/factorizations are made to getaddrinfo internals in the future.
