vt: 32b glyph: 1. Make consolemap.c handle Unicode planes outside BMP

For this, add a fourth layer "planes" onto the sparse map in
this file. Also handle glyph numbers up to 2^21 rather than
256/512. Move the conversion between __user and kernel data
from consolemap.c to vt_ioctl.c.

Why do you do this?

#include <linux/string.h>
-static unsigned short translations[][E_TABSZ] = {
+static u1632 translations[][E_TABSZ] = {

This breaks the build at this point, right?

u1632 is a bad name though.

Given the above, perhaps you should have?
