configure.ac: Only require GStreamer core >= 0.10.2

Original commit message from CVS:
* configure.ac:
Only require GStreamer core >= 0.10.2
Detect version of core the bindings are being compiled against and
write gst/gstversion.override file with eventual API additions that
should be ignored.
* gst/Makefile.am:
* gst/base.defs:
Added gst_base_sync_[set|get]_[sync|max_lateness]() and
gst_type_find_helper_get_range() definitions
* gst/gst-0.10.3.ignore:
API added in gstreamer core 0.10.3
* gst/gst-0.10.4.ignore:
API added in gstreamer core 0.10.4
* gst/gst.override:
Include gstversion.override.
* gst/gstversion.override.in:
Magic file for API additions to ignore.
