Re: Idea for synchonous logging/review of debug + GSMTAP

one of the problems when debugging PCU issues is: How to take proper logs on-site where a problem shows up and give them back to the developer(s) for analysis. If you capture the PCU stdout or configure file-based logging, you will have a hard time corellating that with PCAP traces taken on the RLC/MAC side and/or on the Gb side. Therefore I propose a new idea here and would like to get your review: What about implementing a "GSMTAP" log target for libosmocore? This way we could encapsulate the log messages into a special GSMTAP message, which would be sent synchronously in the GSMTAP stream together with RLC/MAC messages on the lower end.
