docs: Build an rdata object from wire format
  
      This function attempts to dynamically load a class which
      implements the specified rdata class and type.  If there is no
      class-and-type-specific implementation, the GenericRdata class
      is used.
  
      Once a class is chosen, its from_wire() class method is called
      with the parameters to this function.
  
      @param rdclass: The rdata class
      @type rdclass: int
      @param rdtype: The rdata type
      @type rdtype: int
      @param wire: The wire-format message
      @type wire: string
      @param current: The offet in wire of the beginning of the rdata.
      @type current: int
      @param rdlen: The length of the wire-format rdata
      @type rdlen: int
      @param origin: The origin to use for relative names
      @type origin: dns.name.Name
      @rtype: dns.rdata.Rdata instance
