*	fix some validation checks in dns response parsing code	Rich Felker	2014-06-03	1	-2/+3
\| \| \| \| \| \| \| \|	since the buffer passed always has an actual size of 512 bytes, the maximum possible response packet size, no out-of-bounds access was possible; however, reading past the end of the valid portion of the packet could cause the parser to attempt to process junk as answer content.
*	switch standard resolver functions to use the new dns backend	Rich Felker	2014-06-02	1	-0/+31
	this is the third phase of the "resolver overhaul" project. this commit removes all of the old dns code, and switches the __lookup_name backend (used by getaddrinfo, etc.) and the getnameinfo function to use the newly implemented __res_mkquery and __res_msend interfaces. for parsing the results, a new callback-based __dns_parse function, based on __dns_get_rr from the old dns code, is used.
