Add definitions of what we expect the types to be for the values in
XendConfig and apply them when parsing SXP where all values are either
strings or list.
Also fix missing stdvga in HVM config.

the node gets deleted, and can't reliably shut the backend down.

Tidy up argument parsing a little while I'm here.

closely match that of other devices.
This involves moving the logic for backend creation out of the image
handlers and in to the device handler, which is a much more sensible
place for it.

extensively hacked based on feedback from xen-devel.
Its architecture is comparable to the common split device driver
architecture: xenfb and xenkbd modules serve as frontend in domU, and
the user space vncfb or sdlfb process serves as backend in dom0.

For current CR8 acceleration, we do not call update_tpr_threshold() at
every VMEXIT. But at some situations, we cannot inject guest
interrupts in time. And at some critical time, it will bring up a blue
screen to 64bit Windows guest.
Now, we select to call update_tpr_threshold() at very VMEXIT
time. It's safe, and we do not see clear performance downgrade so
far.

the VM UUID conflicts as well.
Also, remove the previous_restart_time node when explicitly rebooting a guest --
the user ought to be able to drive reboots faster than the safety catch.

Added a recreate call to ImageHandler, allowing the subclasses of that to
hook into the code that runs when xend restarts. This allows us in particular
to reregister the watches for HVM shutdown, and read the PID of qemu-dm from
the store.

In some situations, like when error happens in block attach for
a guest in dom0, backend send us XenbusStateClosing notification.
However, as frontend were never properly initialized, it fails
to change its own state to XenbusStateClosed, leaving the system
in a dead-end state.

The data buffer is only 1280 bytes long but the user-supplied length
can be as large as 0x7ff. This patch extends the buffer to 2048
bytes.
