Subject: Module logging:
X-Git-Url: http://jsfdemo.indexdata.com/cgi-bin?a=commitdiff_plain;h=55828a604917e226a1017a80917b7e6f2e3a3d5a;p=yaz-moved-to-github.git

Module logging:

- Called without log level (debug,log,warn,fatal) then log. Existing module logging will work.
- Called with a  log level, then only log if that log level is enabled.

A futher refinement could be to have independant log level.
