The KD_FONT_OP_SET/GET operations hardcode vpitch to be 32 pixels,
which only dates from the old VGA hardware which as asserting this.

Drivers such as fbcon however do not have such limitation, so this
introduces KD_FONT_OP_SET/GET_TALL operations, which userland can try
to use to avoid this limitation, thus opening the patch to >32 pixels
font height.
