lavfi: add init_opaque callback
This will be used by filters which require an opaque field to be passed
in input. Should be required only for filters which imply a programmatic
use.
This is possibly a temporary solution, to be removed when we'll have a
clearer and better agreememnt of how/if to pass binary data for
initializing a filter.
