/* prop.c - rsyslog's prop object
*
* This object is meant to support message properties that are stored
* seperately from the message. The main intent is to support properties
* that are "constant" during a period of time, so that many messages may
* contain a reference to the same property. It is important, though, that
* properties are destroyed when they are no longer needed.
*
* Please note that this is a performance-critical part of the software and
* as such we may use some methods in here which do not look elegant, but
* which are fast...
