resolv: Move ns_name_ntop to its own file and into libc
Reformat to GNU style.  Avoid out-of-bounds pointer arithmetic
(e.g., use eom - dn < 2 instead of dn + 1 >= eom).  Inline the
labellen function and fold the compression pointer check into
the length check (l >= 64).  Assume ASCII encoding.

The symbol was moved using scripts/move-symbol-to-libc.py.
