Add support for nowrap mode CSI ? 7 l (unfortunately, on ANSI.SYS it
is CSI = 7 l; which means that the only way to support both is to
print both sequences and then erase the resulting garbage.)

Some video modes support up to 8 different pages, the current one being
stored at 0x462.

The display page value is passed in BH when invoking the INT 10h Video
Service routines. This patch changes the interface of ansicon_write_char
and ansicon_set_cursor to allow the caller to specify the page.

GNU C allows the ellipsis (...) to be used in case statements to
indicate a range.  However, it requires spaces around it to be valid.
Nindent stripped those off, put them back.

Automatically reformat com32/lib/sys/ansi.c using Nindent.

Do this for all files except HDT, gPXE and externally maintained
libraries (zlib, tinyjpeg, libpng).

If we get a ^G, issue a beep.

Default to \n -> \r\n conversion in the ANSI and xserial modules,
rather than relying on escape codes to make that behave.  This
effectively means that as far as the serial port is concerned, this
behavior cannot be turned off (with less than having the xserial state
machine interpret this sequence) and the escape code *should not* be
used.

That is fine for our applications, though.

In struct term_state and its initialized instance default_state:

Remove duplicated initialization of .xy
Remove unused field .attr
