Rework message and call attribute storage 

Most of the attributes (displayed data in columns in CallList) can
be obtained from payload or packet header. Avoiding data duplication
reduces a lot memory consumption and parsing speedup.

All attributes are now calculated when required, so the parsing
proccess is also faster.
