UBUNTU: SAUCE: vt -- maintain bootloader screen mode and content until vt
switch
Introduce a new VT mode KD_TRANSPARENT which endevours to leave the current
content of the framebuffer untouched. This allows the bootloader to insert
a graphical splash and have the kernel maintain it until the OS splash
can take over. When we finally switch away (either through programs like
plymouth or manually) the content is lost and the VT reverts to text mode.

Bug description:
I'm on Ubuntu 20.04. After upgrading from linux 5.4.0-26-generic to
5.4.0-31-generic I could not log in anymore. I was stuck in the
display manager. Then I rebooted into the old kernel and sent these
reports. I'm not sure if this is related but I can't put my display
onto the correct resolution anymore.
