hello2 — stdio vs conio output API comparison (fast/no-attr vs
slower/attributed), also exercises textcolor/textbackground.
simple — packed 2-bit style array bit-twiddling smoke test.
banktest — __banked function calls across two explicit banks in huge
memory mode.
hello2.c updated to call the renamed gettextmode/settextmode (see the
conio rename in 5e5e70d).

* hello — smoke test for the two output APIs:
|
|
*
|
|
* stdio (printf/puts/putchar) — FAST, no attribute (ambient colour)
|
|
* conio (cprintf/cputs/putch) — SLOWER, applies textcolor/textbackground
|
|
*
|
|
* Demonstrates textcolor/textbackground (Turbo-C-compatible names).
