- Add tons of ASSERT_IRQL / ASSERT_IRQL_EQUAL

Browse source 
- Queue a dpc when IServiceGroup::RequestService is called above dispatch level
- As a result writing to common buffer and completing irps can be done at the same time
- Start the stream at PASSIVE_LEVEL
- Check if key has been deleted in IRegistryKey object function
- Implement IRegistryKey::QueryRegistryValues
