Apple2: Make 80-columns support dynamic on apple2 target

Browse Source 
Add a machinetype identifier to help us quickly identify
Apple //e (bit 7) and //e enhanced (bit 6).

Use it in conio functions for 80-columns code instead of
relying entirely on the __APPLE2ENH__ target.

Move videomode() to the apple2 target, and have it return
an error if 80-columns hardware is not available - this
is a lie for now, it is considered available on //e enhanced,
which may not be true, and not available on //e, which
may also be not true. An ulterior patch will make that
check correctly.

Adapt the box/line drawing characters so that one can use
MouseText on the apple2 target if it is available, by
defining DYN_DRAW_BOX. No change by default: MouseText is
considered available on apple2enh and not available on
apple2.

Note that the second hires page is only available if the text display is not in
80 column mode. This can be asserted by calling <tt/videomode (VIDEOMODE_40COL);/
before installing the driver.
The function <tt/tgi_apple2_mix()/ allows to activate 4 lines of text. The
function doesn't clear the corresponding area at the bottom of the screen.
