[M] Change in osmocom-bb[master]: mobile: init TCH state earlier (on receipt of CC ALERTING)

Attention is currently required from: jolly, pespin. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmocom-bb/+/35739?usp=email to look at the new patch set (#2). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: mobile: init TCH state earlier (on receipt of CC ALERTING) ...................................................................... mobile: init TCH state earlier (on receipt of CC ALERTING) During a Mobile Originating voice call, we would normally start receiving traffic indications with ringback tone (or even some melody) before the call gets CONNECTed. So in order for the user to be able to hear that, we need to init the voice call handler earlier (on receipt of CC ALERTING message). We should not be transmitting voice/data frames before the call gets CONNECTed, so add 'rx_only' flag to the TCH state. In tch_send_msg() drop msgb if this flag is set. Rx only mode makes no sense for data calls, so in tch_recv_cb() we discard received DL frames and thus do not trigger sending UL frames.
