Subject: srd: Pass metadata to decoders only on SR_DF_HEADER.
Before this was passed to the decoder's constuctor, but the parameters
may not all be known at construction. Decoders now have a method start()
which is called at the start of the capture, and metadata is passed as
an arg to this function.
