[ltt-dev] Stub for ltt trace file format

[Matthew Khouzam]

Hello world,

I am working on a java implementation of the trace file format. This is 
a great chance to make documentation catch up a bit to the code. I 
started a wiki article here : 
http://lttng.org/tracingwiki/index.php/Tracing_file_format . Comments 
are more than welcome.
If you see
??? it means I have no idea.
? means I think it should do something but I would appreciate confirmation.
