Common matching frame work
Currently the following parts of Icecast do client and client-status matching:
<resource>-
<role>(auth) -
<header>(child of<http-headers>) -
<event>(child of<event-bindings>)
We also expect the following new users soon:
-
<acl>(child of<auth>)
A common framework should be written to allow implementing matching.
This depends on #2349 (for refobject).
