Pull up following revision(s) (requested by tsutsui in ticket #1518):
sys/arch/atari/dev/ite.c: revision 1.82
sys/arch/atari/dev/ite_cc.c: revision 1.45
sys/arch/atari/dev/ite_et.c: revision 1.36
sys/arch/atari/dev/itevar.h: revision 1.15
Add a minimum DEC special graphics character support for atari ite(4).
This closes PR port-atari/46647 (Menu borders in sysinst appear as
characters with diacritical marks instead of graphics characters).
Switching encoding support by "ESC ( <F>" sequence for vt220 was
pulled from x68k ite(4) (that already supports ISO-2022-JP and EUC-JP).
Note atari's fonts already include DEC special graphics characters.
ET4000 on Hades is untested due to long-term lack of hardware.
Discussed on port-atari@ etc.
