use GVariant for passing decoder options and probes

Decoder options are now exposed in struct srd_decoder, via a GSList
of the new struct srd_decoder_option. The 'def' field represents
the default value as set in the decoder, converted to GVariant. This
allows a library user to determine the type as well as default value.
