ruby CVS updates

Hi all!
     ruby-2.6 moving. Now /dev/tty0 must work correct. /dev/tty0 now
works similar Linus tree kernel. /dev/tty0 is current for each VT. We have
multiple current ttys. Process get current tty depend from VT , where
process
was spawned. Now VCs of VT are shifted. VGA has vc:1-16. DUMMY has only one
VC per VT.
     Keyboard leds switch incorrect when user switch from one VC to another
- this one fixed now.
     Uploaded initial version of framebuffer console. Thanks James Linus
tree kernel already has ruby friendly fbcon code. Porting to ruby is
relative
easy. fbcon right now can serve only one framebuffer device driver
correctly.
Real multiuser, where each fb device has a keyboard, will be added in
future.
If You will test this code, then please select one fb device driver only.
In
my case, fbcon works with Voodoo3. Of course fbcon contain some bugs. You
have
simple arithmetic - if I not clean vgacon during one year, then fbcon is
hopeless :-( Oops You can do via ioctl on /dev/fbX , because they are
untested
and dangerous. fbcon take over VGA console. In real-multiuser case each new
fb device should not take over VGA - we must have kernel command line
options
for each framebuffer device driver. All fb drivers use one fbcon.

TODO: sync to recent kernel.
