[CFR] Upgrading base version of our resolver in libc to BIND9

[Peter Wemm]

From the patch:

-#define        h_errno (*__h_error())
+#define        h_errno (*__h_errno())

....

 /* DO NOT USE THESE, THEY ARE SUBJECT TO CHANGE AND ARE NOT PORTABLE!!! 
*/
-int    * __h_error(void);
+int    * __h_errno(void);

This is a significant ABI change.  Anything that references the public 
"h_errno" definition will no longer link against the new libc.
