[syslog-ng] XML entities in PatternDB

[Balint Kovacs]

Hi Martin,

patterndb uses GMarkupParser from glib to process the xml, which 
unfortunately has quite limited support of entities, a description of 
what is supported can be found here: 
http://developer.gnome.org/glib/2.28/glib-Simple-XML-Subset-Parser.html#glib-Simple-XML-Subset-Parser.description

Basically only the most common 5 entities can be used. If you add the 
nonprintable char to your patterndb as is, it should work as a literal 
match, but is not easy to maintain of course.
