Upstream commit "gio: Port GThreadedResolver to use res_nquery() to fix
thread-safety" introduced a bug that causes compile failures on
platforms where res_nquery is unavailable. This patch fixes that.

Bug 794606 has been opened upstream: https://bugzilla.gnome.org/show_bug.cgi?id=794606

On the OpenWrt buildbots this bug is visible during the arc_archs
compile:

  gthreadedresolver.c: In function 'do_lookup_records':
  gthreadedresolver.c:875:16: error: 'res' undeclared (first use in this function); did you mean '_res'?
     res_nclose (&res);
                  ^~~
                  _res
  gthreadedresolver.c:875:16: note: each undeclared identifier is reported only once for each function it appears in
  Makefile:3334: recipe for target 'libgio_2_0_la-gthreadedresolver.lo' failed
  make[8]: *** [libgio_2_0_la-gthreadedresolver.lo] Error 1

The automake template does not specify libgobject-2.0.la as _LDADD dependency
for glib-compile-resources, leading to the following linker error:

  .../ld: warning: libgmodule-2.0.so.0, needed by ./.libs/libgio-2.0.so, not found (try using -rpath or -rpath-link)
  ./.libs/libgio-2.0.so: undefined reference to `g_module_supported'
  ./.libs/libgio-2.0.so: undefined reference to `g_module_symbol'
  ./.libs/libgio-2.0.so: undefined reference to `g_module_close'
  ./.libs/libgio-2.0.so: undefined reference to `g_module_error'
  ./.libs/libgio-2.0.so: undefined reference to `g_module_open'
  collect2: error: ld returned 1 exit status

This commit introduces a patch to add the missing libtool archive to the list
of libraries to link.

Due to the update of the .am file, a full autoreconf is required to update
configure and Makefile, leading to the following error:

  error: HAVE_GTK_DOC does not appear in AM_CONDITIONAL

Therfore another patch is added to properly fix the conditional when using
automake-1.15.

Finally extend the copyright year in the Makefile and enable the generic
autoreconf fixup to properly build and link glib2.
