This fixes an issue by adding bounds checking to multi-byte packets
where the PS/2 mouse data stream may become corrupted due to data being
discarded when the PS/2 ringbuffer is full.
Interrupts for Multi-byte responses are postponed until the final byte
has been queued.
These changes fix a bug where windows guests drop the mouse device
entirely requring the guest to be restarted.

Cleanup: Create and use a typedef for PS2State and stop passing void
pointers. No functional change.

Commit 8b0caab0 ("ps2: add support for mice with extra/side buttons")
accidentally swapped right and middle mouse buttons. This commit corrects
the mapping as expected by the ps2 controller.

This enables the ps2 controller to process mouse events for buttons 4 and 5.
Additionally, distinct definitions for the ps2 mouse button state are
introduced. The legacy definitions from console.h are not used anymore.

Minimal patch to get the switchover done. We continue processing ps/2
scancodes for now as they are part of the live migration stream. Fixing
that, then mapping directly from QKeyValue to HID keycodes is left as
excercise for another day.

Add a linked list of keyboard handlers. Added handlers will go
to the head of the list. Removed handlers will be zapped from
the list. The head of the list will be used for events.
This fixes the keyboard-dead-after-usb-kbd-unplug issue, key events
will be re-routed to the ps/2 kbd instead of being discarded.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.
