Subject: [PATCH] Add IBM TS1160 density codes to libmt and the mt(1) man page.

These are taken directly from the density report from a TS1160
tape drive.  (Using mt getdensity)

A TS1160 drive stores 20TB raw (60TB with compression) on a JE tape.

lib/libmt/mtlib.c:
	Add 3592A6 encrypted/unencrypted density codes, and bpmm/bpi
	values.

usr.bin/mt/mt.1:
	Add 3592B5 encrypted/unencrypted density codes, bpmm/bpi
	values and number of tracks.  Bump the man page date.

MFC after:	3 days
