dyn TS: common TCH/F_TCH/H_PDCH implementation
common/l1sap: For dyn TS, the BSC will issue RSL Chan Activ requests with a
non-standard chan_nr. While the rest of the code now understands that, the L1
phy will not. Translate to standard PDCH (== TCH/F).
common/oml: use dyn TS' current pchan mode for lchans config.
common/pcu_sock: detect desired PDCH mode of dyn TS.
common/rsl: implement reconnection chain of a TS for changing its pchan:
* rsl_rx_chan_activ():
** Add dyn_pchan_from_chan_nr() to derive the requested pchan from the RSL
chan_nr IE.
** Notice the need for a pchan change and invoke dyn_ts_l1_reconnect() (s.b.)
** Make Chan Mode IE presence optional, because the non-standard PDCH
activation message is simpler and does not require it.
** Do PDCH activation via PCU.
* Add dyn_ts_l1_reconnect(): store state and disconnect the L1 channel;
then wait for cb_ts_disconnected().
* Add osmo_dyn_ts_disconnected() to cb_ts_disconnected():
verify state and connect with the new pchan type; then wait for
cb_ts_connected().
* Add osmo_dyn_ts_connected() to cb_ts_connected(), which re-issues
the cached chan activation message from before disconnecting the L1 channel.
* Also send an rf chan rel/act ack for dyn TS upon PDCH de/act via PCU.
* Add dyn_ts_pdch_release(): on channel release of a dyn TS in PDCH mode,
release via the PCU. Call from rsl_rx_rd_chan_rel().
