Change subject: tweak fsm_msc_mgcp FSM and FI name
......................................................................
tweak fsm_msc_mgcp FSM and FI name
Instead of
MGW(MGW_99)
use a name of
msc-mgcp(MSISDN:2331_GERAN_A:00000017_trans99)
1. The FSM is communication towards an MGW, not the MGW itself. When reading
combined logging (gsmtap_log), it is confusing to read 'MGW' in a log coming
from the MSC. The API is also called msc_mgcp_*.
2. Calling the FSM instance 'MGW_' again doesn't make sense.
3. Indicate 'trans' before the trans_id (trans_id was already shown, but not
indicated what it was).
4. Also indicate the actual subscriber's identification.
5. Also indicate the RAN connection and conn_id.
This comes up while trying to understand a call coming in on an already
established call: parsing the log with a human brain is near torture without
this info, taking extremely long to get grips on.
