* return the requested string as the "canonical name" for numeric addresses•••previously NULL was returned in ai_canonname, resulting in crashes in some callers. this behavior was incorrect. note however that the new behavior differs from glibc, which performs reverse dns lookups. POSIX is very clear that a reverse DNS lookup must not be performed for numeric addresses. Rich Felker2011-04-081-0/+1

* add _res (__res_state()) dummyRich Felker2011-04-061-0/+9
* implement if_indextoname and if_nametoindex functionsRich Felker2011-04-052-0/+36
* fix all implicit conversion between signed/unsigned pointers•••sadly the C language does not specify any such implicit conversion, so this is not a matter of just fixing warnings (as gcc treats it) but actual errors. i would like to revisit a number of these changes and possibly revise the types used to reduce the number of casts required.
