ACLs shall support full regural expressions in property values
--------------------------------------------------------------

                 Key: QPID-3892
                 URL: https://issues.apache.org/jira/browse/QPID-3892
             Project: Qpid
          Issue Type: Improvement
          Components: C++ Broker
    Affects Versions: 0.14
            Reporter: Pavel Moravec


Currently ACL syntax supports in a property value either direct match 
("name=RequestQueue") or a substring match ("name=tmp.*").

That is not sufficient when authorizing access to topics. One particular 
example: amq.topic exchange receives messages with keys usa.sports, usa.news, 
europe.sports and europe.news. Currently we can not authorize access just to 
topics *.sports and to usa.* 

As there exist different use cases where regular expressions are required in a, 
it is meaningful to support (full) regular expressions in ACL property values.

Since qpid C++ broker already relies on boost libraries a lot, I suggest (in a 
patch proposed) using boost::regex library.

I tested the attached patch on Fedora, not sure if other Linux distributions 
are familiar with the change in Makefile.am.
