Idea for synchonous logging/review of debug + GSMTAP

Hi all,

Yes, I actually have many problems when debugging PCU too, so I think
that using GSMTAP is good solution, because it is fast solution, and
it will be really helpful.
About human-readable PCU log messages, I think that using prefixes is
normal, but we should use TFI+TLLI for prefix, because especially for
PCU debugging it is very important to have ability to control
particular TBF.
