term: performance: use a bitfield to track which ascii printer to use

Browse source 
The things affecting which ASCII printer we use have grown...

Instead of checking everything inside term_update_ascii_printer(), use
a bitfield.

Anything affecting the printer used, must now set a bit in this
bitfield. This makes term_update_ascii_printer() much faster, since
all it needs to do is check if the bitfield is zero or not.
