Don't display the cursor on the graphical screen while doing a quiet
boot.  When doing a quiet boot we will probably show the graphical
screen for a fair bit of time; as a result, we really don't want a
completely bogus cursor blob on the bottom of the screen.

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.

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

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

Even when disabled, we need to set the screen size, because the
downstream code depends on it.  Set it to 25x80 (maybe we should
swtich this is 24x80) in this case.

Furthermore, when disabled, we should return success == bytes
"written", not zero.

If we get a ^G, issue a beep.
