Small patch to ber.c The tcap dissector has been updated to use this length. I have not tested other asn.1 dissectors to ensure that they correctly use the indefinite encoding flag instead of the length value returning zero. There may also be some problems when re-assembly is needed, but the ability to deal with indefinite length is much more useful. For developers the get_ber_length now returns the length of the pdu including the EOC, where you have dissectors that use packet-ber.c the eoc may need to be dealt with separately. The tcap dissector has had numerous changes to make it less cluttered, and the useful feature of the previous version where a dialogue could be filtered out by selecting either the source or destination transaction ID has been incorporated into this version. svn path=/trunk/; revision=15414
