Change subject: sigProcLib: Fix number of tail bits in random Normal Bursts and zero Stealing Bits. ...................................................................... sigProcLib: Fix number of tail bits in random Normal Bursts and zero Stealing Bits. This bug only affects generation of normal bursts filled with random bits which are used in test mode. It doesn't affect operation of osmo-trx during normal operation. That's why it has stayed unnoticed for so long. Each Normal Burst has 3 tail bits, not 4. Also it's better to set stealing bits to 0 for maximum compatibility. We may want to introduce a selector for each bit whether to set it to 0, to 1 or to a random number.
