libmsc/ussd: implement basic USSD session management
During some long period, including the OpenBSC time, the USSD
processing code was (and still is) pretty trivial, so there
was no transaction management, nor connection reference
counting.
Meanwhile, according to GSM TS 04.10, section 2.2.6 "Multiple
supplementary service invocations", call independent SS/USSD
transactions can exist in parallel with other CM-Layer and MM
transactions. Several call independent SS/USSD transactions
can be used simultaneously.
Thus, a single USSD session is identified by:
- MM / CM connection (pointer address),
- Transaction ID (see TS GSM 04.08).
This change introduces a new structure, named 'ussd_session',
that corresponds to a single SS/USSD-session, and allows a
subscriber to have a few concurrent sessions in parallel.
Also, this facilitates the further implementation of network
originated SS/USSD-sessions, and the development of external
USSD interface.
