This is a fork of google guice with a number of patches added to support GuiceyFruit

• 354 provide a way to iterate through all objects in a scope
• 343 OSGi fix: BytecodeGen uses system classloader when applying AOP to system types
• 337 OSGi fix: AssistedInject needs class load bridging under OSGi
• OSGi patch to export com.google.inject.internal so that GuiceyFruit can access it without using Fragments (which can't use exports in Felix)
