[jboss-as7-dev] [AS7-5477] Allow processing of the module phase to be deferred

[Thomas Diesler]

Stuart,

I implement the first cut of this as we talked about.

The DeferredModuleUseProcessor adds a the module service as a dependency 
on the next phase, which is FISRT_MODULE_USE. This is actually something 
I previously already did for resolved bundles - now I do it always in 
this DUP.

The DeploymentUnitPhaseService makes Phase.FISRT_MODULE_USE passive if 
it sees explicitly named services in 
Attachments.DEFERRED_MODULE_DEPENDENCIES

The processing is currently limited to OSGi only and this patch should 
not effect other deployment types. The OSGi testsuite passes completely 
with a few deployments hanging in Phase.FISRT_MODULE_USE before they 
triggered to proceed by an explicit API call which resolves the bundle 
and hance makes the module service available.

TODO:

* Think about whether Phase.FISRT_MODULE_USE should always depend on the 
Module service
* Remove all module == null checks in FISRT_MODULE_USE DUPs and after.

cheers
