sgsn: Create an initial and limited CDR module
This is consuming the new signals and allows to install several different CDR/observing/event/audit modules in the future. For getting the bytes in/out the code would have had to undo what the rate counter is doing and at the same time adding a "total" to the ratecounter didn't look like a good idea, the same went for making it a plain counter. Begin writing the values one by one and open/closing a new FILE for every log messages. This is not efficient but easily deals with external truncation/rotation of the file (no fstat for and checking the links and size). As usual we will wait and see if this is an issue. Add some new members to our PDP context structure to see what it is about.
