[finish backporting from trunk]

* The mapping file requires a recent version of XmlConfiguration (>= 1.0.24)
* Privatize our own version of xml-config
* Use it in the dependencies
* Revert the global ${ow-bundle.version} property back to 1.0.19

(Git help for merge but does not prevent you from lazy mistakes :) )

[backport from trunk]

* Enable filtering at module level
* Standalone EAR, WebApp and EjbJars are supported
** Rars filtering are configured throught the EAR's META-INF/classloader-filtering.xml
* The system filtering is only defined for OSGiClassLoader (as it's the parent of all our applicative ClassLoaders)
* WebApp inside EAR also have supports for filtering ClassLoader

[backport from trunk]

* FilteringClassLoader now has to be configured with an XML definition file
** Either the File from the system (conf/classloader-default-filtering.xml)
** Or with a File from the deployed modules
* Added tests for the parsing and admin property to force the loader to be disabled
* Adapted usage of the FilteringClassLoader to the new API
* Centralized TestNG version in parent POM
* Some style
* Added Javadoc
* Added comments into XML mapping file

Only style

Upgrade to 6.0.29 needs changes in versioning if I remember

Fix for #253

fixes #231. modjk's workers.properties file is no more copied in /home/pelletib/jb/jb.sb52/conf of web instance

fix #53 : The working test statement for HSQLDB is: select count(1) from information_schema.system_tables

[Backport from trunk]

To compute the list of deployable, JOnAS first get all the availables files from the repositories
and then remove the one(s) that are already deployed. For all known types (ejbjar, webapps, ...)
but not for deployment plans.

Fixed by adding a check testing if the given URL is a deployed plan. 

Fix #247 : When the development attribute is re-enabled, get the current state as base AND don't forget the deployment plans :)

> Backported from rev 19508 (5.2.x)

* Add the root RAR URL in the ClassLoader
* Refactored a bit the file name manipulation (introduced File usage !!)
* Filter the Externals ClassLoader (the loader injected with URL from standalone RAs)
* Instanciate and start the RA class under the right Thread ClassLoader
* More URLUtils usage (Safe File 2 URL convertion)
* Close opened resource adapter rar file after extraction 

#235

Attempt to fix #224 : if RoleBasedAuthorizationModule is not here yet, take some sleep. It should eventually come, if not throw exception saying that the 'security' service needs to be enabled.
