- add support of session management for tcap ANSI.
(In fact, this support already exist for ANSI MAP subdissector, but as our
simulators can reuse the tcap transaction Id, the decoding of the response
may be wrong)
- move the code related to asn1 in tcap.cnf, and update tcap.cnf
- move the code related to the session management in tcap-persistentdata
- add a compilation option to free the entry in the hashtable for a closed
transaction. This is used only for tshark statistics generation, with huge file.
- cleanup and add some comments
Add Id tags to epan/tcap-persistentdata.{c,h}
