This patch adds the convolutional code definitions for CSD (circuit
switched data) on TCH/F channels with user bit rates of 2400, 4800, 9600
and 14400 bps.

AMR SID update frames are protected using an 1/4 convolutional coder,
wich is similar to the one used with 6,7 kbit voice frames. Except that
there is no puncturing and the length is different.
