[erlang-questions] Should we deprecate or modernize log_mf_h and rb?

I really like this "old" error logger, it's *easily* one of the fastest
around actually, since it can leave formatting to read time! I've hacked it
to truncate overlong entries. The rb application is also easily hackable to
suit your needs. I have a version that looks up formatting functions based
on a bit of metadata in the logged "messages".

The major boon of being so blindingly fast, is that you do not have to set
log levels at logging time. Instead you choose which log level you want to
see when investigating!

Unfortunately, straight logged binary data and formatting it at read time
appears to be majorly out of fashion :-(

Oh well.

If you want to keep it, I think it would be worth adding the truncation
bit, or make it accept any size log message.
