Lots of infracstructure for the new logging framework.

This pretty much follows the proposal on the projects page.

It includes:

    - A new LogMgr, maintaining the set of writers.

    - The abstract LogWriter API.

    - An initial implementation in the form of LogWriterAscii
      producing tab-separated columns.

Note that things are only partially working right now, things are
subject to change, and it's all not much tested at all. That's why I'm
creating separate branch for now.

Example:

     bro -B logging test-logging && cat debug.log
