BZ 1069606 - initial changes to pom.xml files, dependencies and some other things related so we can build on EAP 6.3.
- arquillian tests throw exception because the jta attribute is here (even though AS allows for it and we are setting it to the default value, not sure why this isn't allowed in tests)
- define xnio deps explicitly so they point to 3.0.10.GA which is what arquillian needs to test that the server is up
- fix security exception "class org.hamcrest.TypeSafeMatcher signer information is different from other classes in same package" when running PC tests
- jboss-as-subsystem-test changed its artifact name - it now has "-framework" at the end of its name
