[9fans] getting rid of kernel kbd maps

[Fco.J.Ballesteros <nemo@plan9.escet.urjc.es>]

We still have (at least) two keyboard drivers, and I
don't like that much.

Would everybody be happy if

1. the kernel included just the std kbd.c driver

2. A user level driver could be started by boot(8)
in those cases where kbd maps are wanted. This
driver could just put the native keyboard in raw mode
and translate runes as it wants (using the maps), then
service fake /dev/cons and /dev/consctl files to pretend
that they are the keyboard.

If everybode is happy with that, and therefore it would
save me from merging our local driver with the distributed
one everytime it changes, I'm willing to do the change.

I say this because I'm about to try what presotto suggested
for the usb keyboard driver (i.e. to bind a fake console file),
and I thought it could be also a way to go back and get
a single keyboard driver for all plan 9 sites.

let me know what you think.
thanks anyway.
