44abe47deb input: Add ANSI 3.64 escape sequence generation.
To support Non-ASCII keys (ex, Fn, PgUp/Dn, arrow keys, ...), we need to
translate key code into escape sequence.

(Updated by sjg@chromium.org to move away from a function to store
keycodes, so we can easily record how many were sent. We now need to
return this from input_send_keycodes() so we know whether keys were
generated.)

1b1d3e6461 input: Separate out keyboard repeat/delay from init
It is inconvenient to have to specify the keyboard repeat and delay at
init time if it is not yet available, so move this into a separate
function.

Some drivers will want to do this when their keyboard init routine
is actually called.

9bc590e511 input: Add generic keyboard input handler
Add a module which understands converting key codes (or scan codes)
to ASCII characters. It includes FIFO support and can call back to
drivers to read new characters when its FIFO is empty.

Keycode maps are provided for un-modified, shift and ctrl keys.

The plan is to use this module where such mapping is required.
