VBoxHDD: First part of the async I/O support

The async I/O interface is not presented to the backend directly anymore but goes through a new interface in VBoxHDD doing the request management
Implemented everything to make the old coe work again
Async I/O completely disabled for now because it is not working atm (the old code for VMDK was removed)

Property svn:eol-style set to native
