configure.ac, server/Makefile.am: Refactor GStreamer autoconfery.

  * Introduce `--with-gstreamer=VERSIONS' configure option, which
    searches for the (space-separated) VERSIONS in order.

  * Pick up the `gstapp' and `gstaudio' libraries from `pkg-config'
    rather than probing randomly at `gstreamer-plugins-base-0.10' and
    hoping for the best.

  * Define a preprocessor symbol explaining which version we found.
