The state of the dyn TS would lock up in the PDCH activation phase since the PCU never completed the process. Make more robust, i.e. don't concern the BSC with PDCH activation failures. This matches the way plain PDCH TS work: besides declaring the TS as PDCH, the BSC is not involved and is not told about errors. During PDCH deactivation, still wait for the PCU to tear down the PDTCH SAPIs, but in case no PCU is connected, send a rel ack right away. Thus, the BSC will happily switch Osmocom style dynamic timeslots to and from PDCH mode, using the dyn TS as voice channels as needed, and not caring about possible PDCH failures. GPRS starts working right away as soon as a PCU connects, regardless of dyn TS having been used for voice any number of times, and without another switchover needed. In detail: In rsl_rx_chan_activ(), upon receiving a PDCH activation, send an RSL chan act ack right away, unconditionally (with an explaining comment). Do not concern the Abis link with PDCH activation failures. Since we're acking right away now, drop the chan act ack that would follow after the PCU activation: as before dyn TS, only send acks and nacks for rel_act_kind == LCHAN_REL_ACT_RSL (PDCH runs as LCHAN_REL_ACT_PCU). In dyn_ts_pdch_release, indicate that the PCU is not connected by means of returning 1. In rsl_rx_rf_chan_rel(), use this indicator to send a rel ack right away if the PCU is not connected.

Add function rsl_tx_chan_act_acknack() to wrap rsl_tx_chan_act_ack() and rsl_tx_chan_act_nack(). Move the decision whether to drop the ack/nack, based on lchan->rel_act_kind, to the new function, losing some code dup. Change all callers to use the new function; drop the two older ones from rsl.h and make them static. Note: for nack, the exception for dyn TS in PDCH mode was missing (rsl_tx_chan_act_nack() had only the rel_act_kind != LCHAN_REL_ACT_RSL condition, but should also have had the dyn TS exception as in rsl_tx_chan_act_ack()). I already know that this exception will again be removed in an upcoming commit, but for patch readability it logically makes sense to add it here. To easily include the nack case, drop the check for which pchan the dyn TS is operating as, because a rel_act_kind == LCHAN_REL_ACT_PCU implies that it is either already in or trying to become PDCH mode.
