Subject: [PATCH 04/11] Updating autogen and configure

* autogen.sh: (a) removing the call to configure, printing an invitation
  to do so instead; (b) creating build-aux/config.rpath if it does not
  exists: this because we use configure.ac uses the guile.m4 GUILE_FLAGS
  macro, among others, which needs this file, not installed anymore by
  modern version of automake, iiuc, and without it, autogen raises an
  an error. For why it's needed, see the comments in m4/guile.m4.

* configure.ac: Adding a copyright; bumping prereq -> 2.69, version ->
  0.2.3-dev; let's use build-aux, m4; automake -> 1.14, serial-tests;
  checks/looks for guile 2.2, 2.0; cleaning HAVE_GUILE_COMPILE checks,
  we always have access to a compiler: in the end this wil disappear,
  but we kept and set HAVE_GUILE_COMPILE=1 still used 'en aval'; calling
  GUILE_GLOBAL_SITE_DIR and GUILE_SITE_CCACHE_DIR, we'll use them in
  Makefile.am.
