Description

this involves PCU, BTS and BSC. This ticket is about the PCU part.

The PCU-BTS API already permits for dynamic addition/removal of PDCHs. Not sure if it is sufficient, but the basics are there.

On the PCU side it appears like all required code is in place, but it requires testing.

As part of this ticket it was assumed that we need to add an ACK message
from the PCU for PDCH deactivation.

During PDCH deactivation, we call pcu_tx_info_ind() to update the channel
infos towards the PCU. The PCU already responds with a channel deactivation
message to the BTS, so it seems there is in fact no change needed for the PCU.

(not changing the % Done until verified.)

osmo-pcu in fact needs no changes for dyn PDCH at all, as verified by the sysmoBTS implementation.
On pcu_tx_info_ind(), osmo-pcu properly responds with activation and deactivation requests to the BTS.
