Jacob Erlbeck 612e93e360 llc: Add put_dummy_frame to create an LLC dummy command 
The LLC dummy command is needed for RLC block stuffing, e.g. when a
TBF should be kept open if no LLC data is available. The RLC block
headers do not support stuffing, only the last block of a TBF can be
used partially. LLC dummy commands are discarded by the receiver
immediately, because the have an invalid FCS checksum.

This commit adds the function put_dummy_frame, which puts a LLC dummy
command into the frame buffer. The requested length is given as an
argument, but the real length might be adjusted according to the
specification (see GSM 44.064, 6.4.2.2).
