CVE-2016-3706: getaddrinfo: stack overflow in hostent conversion [BZ #20010]
When converting a struct hostent response to struct gaih_addrtuple, the gethosts macro (which is called from gaih_inet) used alloca, without malloc fallback for large responses. This commit changes this code to use calloc unconditionally. This commit also consolidated a second hostent-to-gaih_addrtuple conversion loop (in gaih_inet) to use the new conversion function. (cherry picked from commit 4ab2ab03d4351914ee53248dc5aef4a8c88ff8b9)
