1) ShellPkg/Library/UefiHandleParsingLib
    a. UefiHandleParsingLib.c – ConvertHandleToHandleIndex() and ConvertHandleIndexToHandle()
        i. Update to work correctly when handles are destroyed due to driver disconnect operations.  Same handle index is never reused.
    b. UefiHandleParsingLib.c – ParseHandleDatabaseByRelationshipWithType() and ParseHandleDatabaseForChildControllers()
        i. Expand to handle Service Binding Protocol usage such as Network stack.
2) ShellPkg/Library/UefiShellDriver1CommandsLib
    a. DevTree.c – Fix bug where the same handle is shown more than once.
    b. Dh.c – Fix use of GetDriverName() and GetDriverImageName().  The status returned must always be evaluated. 
    c. Disconnect.c – Remove requirement that a handle being disconnected must support Device Path Protocol.  This prevents driver model handles without device paths from being disconnected (i.e. Network Stack)
    d. OpenInfo.c – Fix bug when showing open info about a ControllerHandle that has been destroyed due to a disconnect or an unload operation.
    e. UefiShellDriver1CommandsLib.uni – Fix “drivers” command formatting when handle indexes have more than 2 characters.
