lapd_core human readable connection IDs in debug log
At the moment we print the pointer address to identify the log lines belonging to a specific connection. Since pointer addresses are difficult to work with, a human readable ID should be printed instead.
e.g. "This is LAPD instance for SAPI3 on bts0/trx1/ts5/lchan3"
This can be implemented by adding a string member to the lapd_datalink struct. The user would set the string to a human readable identifier when the link is created. (See also osmo_fsm).
