no reason to append referrer for debug lines...

frequent messages on real site (not a development site) are due to bad
links (file not found and probably others)...  referrer can be nice...
 maybe it should have been added by the caller of ap_log_rerror() for
messages which were likely to be triggered by bad links???  or maybe
just eliminating it from debug lines is reasonable improvement

pid and thread id in a fixed location would be nice too


consider this:

. make current referrer implementation a bit more practical
. defer custom formatting of error log messages to a module, changing
existing error log hook if necessary to provide necessary capabilities
