fsms: use configurable timers instead of T23042
T23042 was a placeholder for timers to be filled in later. Replace it with timers that can be configured via VTY.
Previous timeout for the states was 5s, from using the default of 5 for undefined timers.
* ASSIGNMENT_ST_WAIT_MGW_ENDPOINT_TO_MSC and HO_ST_WAIT_MGW_ENDPOINT_TO_MSC: * Runs gscon_connect_mgw_to_msc() on enter, which waits for one MGCP CRCX or MDCX response (or changes state immediately) * Use existing X9 ("Timeout for availability of MGW endpoint"), 5s, which is already being used by lchan_rtp_fsm for a similar purpose
* HO_ST_WAIT_RR_HO_DETECT: * Handover initiation as described in 3GPP TS 04.08 § 3.4.4.1: "The network initiates the handover procedure by sending a HANDOVER COMMAND message to the mobile station on the main DCCH. It then starts timer T3103." * Use existing but unused timer T3103 ("Handover"), 5s
* HO_ST_WAIT_RR_HO_COMPLETE: * Handover completion as described in 3GPP TS 04.08 § 3.4.4.3: "When receiving the HANDOVER COMPLETE message, the network stops timer T3103 and releases the old channels." * Continue using T3103 with keep_timer = true
