  ps2: set ps/2 output buffer size as the same as kernel

According to the PS/2 Mouse/Keyboard Protocol, the keyboard outupt buffer size
is 16 bytes. And the PS2_QUEUE_SIZE 256 was introduced in Qemu from the very
beginning.

When I started a  redhat5.6 32bit guest, meanwhile tapped the keyboard as 
quickly as
possible, the screen would show me "i8042.c: No controller found". As a result,
I couldn't use the keyboard in the VNC client.

Previous discussion about the issue in maillist:
http://thread.gmane.org/gmane.comp.emulators.qemu/43294/focus=47180

This patch has been tested on redhat5.6 32-bit/suse11sp3 64-bit guests.
More easy meathod to reproduce:
1.boot a guest with libvirt.
2.connect to VNC client.
3.as you see the BIOS, bootloader, Linux booting, run the follow simply shell 
script:
for((i=0;i<10000000;i++)) do virsh send-key redhat5.6 KEY_A; done

Actual results:
dmesg show "i8042.c: No controller found." And the keyboard is out of work.

  input: key mapping helpers

Add helper functions to translate KeyValue (qapi key representation)
into other representations: traditional qemu key numbers, qapi key
codes (Q_KEY_CODE_*) and scancode sequences.

  input: switch sparc32 kbd to new input api

Nasty 0xe0 logic is gone.  We map through QKeyCode now, giving us a
nice, readable mapping table.

Quick smoke test in OpenFirmware looks ok.  Careful check from arch
maintainers would be very nice, especially on the capslock and numlock
logic.  I'm not fully sure whenever I got it translated correctly and
also what it is supposed to do in the first place ...

With sparc keyboard going directly from QKeyValue to sparc keycodes
this should not be needed any more.
