* fhandler_tape.cc (mtinfo_drive::get_pos): Only set partition if

	GetTapePosition returned a non-zero partition number.
	(mtinfo_drive::create_partitions): Reinitialize to partition 0.
	Support TAPE_DRIVE_INITIATOR and TAPE_DRIVE_FIXED partitioning.
	(mtinfo_drive::set_partition): Initialize new partition.
	(mtinfo_drive::status): Readd accidentally dropped setting of mt_resid.

	* net.cc (wsock_event::prepare): Always print debug output in case
	of error.
