Routine Description:

  Function locates Protocol and/or Handle on which all Protocols specified
  as a variable list are installed.
  It supports continued search. The caller must assure that no handles are added
  or removed while performing continued search, by e.g., rising the TPL and not
  calling any handle routines. Otherwise the behavior is undefined.

Arguments:

  Handle        - The address of handle to receive the handle on which protocols
                  indicated by the variable list are installed.
                  If points to NULL, all handles are searched. If pointing to a
                  handle returned from previous call, searches starting from next handle.
                  If NULL, the parameter is ignored.

  Interface     - The address of a pointer to a protocol interface that will receive
                  the interface indicated by first variable argument.
                  If NULL, the parameter is ignored.

  ...           - A variable argument list containing protocol GUIDs. Must end with NULL.

Returns:

  EFI_SUCCESS  - All the protocols where found on same handle.
  EFI_NOT_FOUND - A Handle with all the protocols installed was not found.
  Other values as may be returned from LocateHandleBuffer() or HandleProtocol().
