Merged DAVEW_V3.2 to HEAD

13659: Fix NTLMAuthenticationFilter to call super.afterPropertiesSet()
   13658: MOB-424: Utility to Dump JMX Data
      - new enterprise distributable jmx-dumper.jar
      - command line invocation via "java -jar jmx-dumper.jar"
      - admin web access via http://localhost:8080/alfresco/faces/jsp/admin/jmx-dumper.jsp
   13575: Preconfigured authentication stacks for alfresco, LDAP, Kerberos and NTLM. TODO: file server config.
   13493: Initial work to enable selection, configuration, testing and hot-swapping of different authentication subsystems via JMX or admin UI.
   13309: Changes to allow datasource and property configuration via JNDI
      - Move AVM catalina .jars into 3rd-party/lib/virtual-tomcat so that they don't get automatically included in the .war file and hence stop JNDI lookups from working
      - Allow JNDI lookup of datasource – use standard app server mechanisms for managing it but still fall back to 'normal' one
      - Allow properties to be overridden by JNDI env-entries as well as system properties. Including hibernate dialect ones. Web.xml can then declare required env-entries and these can be defined on deployment.
      - Rewire iBatis so that no config file edits are necessary when dialect is changed
      - Use proxy around datasource so that auto-commit is always activated for iBatis
