    Stop calling res_init · 93bf7d52

    Emacs shouldn’t need to call res_init any more, now that nscd or
    equivalent is everywhere.  On modern systems, calling res_init
    simply slows Emacs down.  On ancient systems lacking nscd Emacs
    will still work well enough with this change; it’s just that it
    won’t respond to changes in /etc/resolv.conf.
    * configure.ac (HAVE_RES_INIT): Remove.  Worry about -lresolv only
    when configured --with-hesiod.  Hesiod is still used; see, e.g.:

    * src/Makefile.in (LIBRESOLV): Remove.  All uses removed.
