[libvirt] support for qemu werror and rerror

[Vasiliy Tolstov]

Sometimes ago qemu anounced support for action for disk:

werror=action,rerror=action

Specify which action to take on write and read errors. Valid actions
are: "ignore" (ignore the error and try to continue), "stop" (pause
QEMU), "report" (report the error to the guest), "enospc" (pause QEMU
only if the host disk is full; report the error to the guest
otherwise). The default setting iswerror=enospc and rerror=report.

Does somebody can write this support to libvirt ? Or how can i enable
werror and rerror ?
