[Freeciv-Dev] patch: LOG_ERROR (PR#498)

[David Pfitzner <dwp@xxxxxxxxxxxxxx>]

This patch adds a new log level LOG_ERROR, between LOG_FATAL and 
LOG_NORMAL, for non-fatal error messages.  This is intended to 
include non-fatal cases of following:
- Internal code (logic) errors;
- Protocol errors (client/server sent something wrong);
- Data errors (inconsistent ruleset data etc);
- System errors (I/O error, file not found, etc).

I also have a patch which changes various freelog() calls to
use LOG_ERROR where appropriate, but I think I'll wait until
after multi_conn2 is in CVS to post it, to avoid conflicts.
