The ULSCH_id variable is currently defined as uint8_t, which limits its
range to 0-255. However, gNB->max_nb_pusch can exceed this range
depending on the configuration (buffer_ul_slots and MAX_MOBILES_PER_GNB).
This can lead to incorrect behavior or undefined results when max_nb_pusch
is larger than 255. This commit changes the type of ULSCH_id from uint8_t
to int to accommodate larger values of max_nb_pusch.
The issue was observed when running the OAI gNB with MAX_MOBILES_PER_GNB set
to 64 UEs. The root cause was traced back to the changes to UL processing
introduced in !3166 (!2952).

Added 3 way F1 handover test with data exchange in the F1 pipeline.
The major change is that the UE is acting as a server in the handover
scenarion, so it needs to comply with the changes in !3280.
This prevents the UE to use an outdated timing_advance after a re-sync. It prevents the UE to send a PRACH with a wrong TA, thus preventing a RAPID mismatch in Msg2 (example: '[UE 0][RAPROC][0.0] Received RAR preamble (29) doesn't match the intended RAPID (30)')
the standard in 213 8.4 says: "In response to the PDSCH reception with the UE contention resolution identity, the UE transmits HARQ-ACK information in a PUCCH."

Use `rfsimu_channel_ue1`, `rfsimu_channel_ue2`, etc. if you want to
use different channel models for each client. The client connection
order determines its channel model name.
Enable/disable workaround based on a new option "hanging-workaround".
This addresses an issue where the workaround will trigger even if there
is no risk of a permanent lockup of the system.
