[jboss-dev] Is @org.jboss.beans.metadata.api.annotations.Dependency being used?

Commited against https://jira.jboss.org/jira/browse/JBKERNEL-98. I'll post the performance enhancements on the "Small boottime improvement thread"

If you want to have dependencies from annotations, use @org.jboss.aop.microcontainer.annotations.EnableAopAnnotationDependency at bean level similar to @EnableAopProxy for the beans that have annotations using @Dependency, so this checking is disabled by default. I'll fix the kernel/aop-mc-int tests this way and post if something unexpected happens.

AOPDependencyBuilder currently does quite a bit of work looking for these (about 3.5% of default startup time), but I see Ales has done some work on a SecurityDomain annotation plugin which is plugged in as an annotation adapter, but that is only active in some tests.

The only issue with that is that the meta annotation plugins currently only work on class level. So before I try to change that, I want to make sure nobody is using it.
