Create a web-common module and move EE related classes

This commit moves most of the classes that are required
for web container integration into their own module. This
is not a complete solution as yet, as OSGI and Web Services
still have a hard coded dependency on JBoss Web classes.
First try of getting undertow in core AS

* webservices subsystem does not compile
* osgi does not compile
* modcluster does not compile

this three subsystems are disabled for now
make arq work again
More undertow fixes
