check/gst/gstvalue.c: Add a deserialisation test for fractions

Browse source 
Original commit message from CVS:
* check/gst/gstvalue.c: (GST_START_TEST), (gst_value_suite):
Add a deserialisation test for fractions
* examples/metadata/read-metadata.c: (message_loop),
(make_pipeline), (main):
Fix up metadata reading sample.
* gst/base/gstbasesink.c: (gst_base_sink_do_sync):
Debug format fix
* gst/base/gstbasesrc.c: (gst_base_src_default_negotiate):
Don't try and fixate empty caps
* gst/gst_private.h:
Wrap in G_BEGIN_DECLS/G_END_DECLS
* gst/gstvalue.c: (gst_value_collect_fraction),
(gst_value_set_fraction), (gst_value_get_fraction_denominator),
(gst_value_transform_string_fraction),
(gst_value_compare_fraction):
Add some extra guards to ensure that we don't end up
with an invalid denominator of 0 in a gstfraction and
that fractions always get reduced.
