Adding Gerd to the CC, since this is possibly caused by recent work to
keyboard state tracking code.

4.0 breaks keyboard autorepeat in guests with xserver
Status in QEMU:
In a linux/bsd guest within X, pressing and holding a key for a short time
causes an endless repeat of that key in the guest. The release of the key gets
Example 1: pressing and holding 'a' for a few seconds results in typing of
Example 2: pressing and holding 'Backspace' for a few seconds results in
deleting all your previously typed text.
It doesn't happen within a VT in the guest. It also doesn't happen
with guests that run windows, reactos or haiku for example.
The problem goes away when disabling xorgs autorepeat function via "xset -r"
in the host.
Normally, this setting should not have any effect on the guest, since it has
it's own autorepeat setting. So there is some conflict here.
Steps to reproduce:
Start any linux/bsd guest system with xserver, open a terminal, press and
hold a key for a short time: Look how it gets typed endlessly (Try a few times
if it doesn't happen immediately).
The easiest way is to run a linux live cd, like this (Link to example iso
$ qemu-system-x86_64 -enable-kvm -m 512 -net none -boot d -cdrom
