Add option to GSM HR frames to RFC5593 representation

There are different specifications around on how a GSM-HR frame should
be encapsulated into an RTP packet. RFC5593 specifies a ToC (Table of
Contents) byte to be prepended in front of the payload data.

The two formats can be distinguished easily by their length. Then the
data can be formatted into the corresponding opposite format and vice
versa.

- Add new VTY rtp-patch options
- Add conversion function
