gsm0808: add encoder for cause codes and use it
At the moment the all gsm0808 cause codes are encoded directly using the tlv API directly to put a one byte TLV field. This works ok for most situations where the cause code consists of a single byte. However, gsm0808 specifies a two byte cause code model where cause codes may be extended up to two bytes. Instead of implementing the encoding over and over and again, let's rather have an encoder function we can call. - Add an encoder function that can generate single byte and extended cause codeds and makes the length decision automatically. - Use only this function to append cause codes Change-Id: I71d58fad89502a43532f60717ca022c15c73f8bb
