Florian Weimer 762a2b2d34 resolv: Move ns_samename into its own file, and into libc
But only as an internal symbol, __libc_ns_samename.  The libresolv
ABI is preserved.  This is because the function is deprecated, and
it does not make sense to add new symbol versions for deprecated
functions.

Also reformat the implementation to GNU style.
