Fix handling of the entries-per-domain quota.  Entries which are created by
the guest but deleted by dom0 were remaining accounted against the guest,
which meant that the guest would eventually run out of quota.

This patch also prevents unprivileged domains from changing the owner of a
node.  One guest could attack another by creating nodes and then transferring
them to the ownership of another, and though the accounting could be made to
work properly in this case, domains should never be transferring nodes in any
case, so it seems safer just to disallow the operation entirely.

[IOEMU] Fix Linux smp guest hangs with complaint "BUG: soft lock detected on CPU#0"

When console=ttyS0 in guest grub configuration and serial='pty' in vmx
configure file. The root cause to this bug is the characteristic of
PTY emulator in Qemu. PTY has write/read end with some buffer. Write
to a buffer will be failed after the buffer is full until read end
reads the data from buffer.

Previous to changeset 12026, write to serial port would fail quietly
when buffer for pty is full. With changeset 12026, write to serial
port would retry 3 times in 300ms if failed, even without notifying
guest using serial irq. Smp guest will hang, waiting for an
interrupt. For SMP guest, a watchdog thread should be executed
periodically, otherwise soft lockup is detected. With this patch, an
upper threshold of total consecutive retries is added and serial
interrupt would be sent after retry 3 times for each write request,
even if failed.
