Allow xm to spawn vnc viewer
The new merged qemu no longer has the ability to spawn a vnc viewer
process in the bowels of the xend/qemu stack. In this patch we
provide support for this use case in a different manner - one more
akin to the mechanism used for `xm console' and `xm create -c'.
We introduce new xm options:
xm create --vncviewer [--vncviewer-autopass]
xm vncviewer [--vncviewer-autopass]
These spawn a VNC viewer, obtaining the relevant information
(including the port number and if you tell it your viewer supports it
the password to use) directly from xenstore.
Like xm console it waits in the foreground for the vnc port to become
available; the timeout case isn't handled as well as it might be - it
just causes the whole program (xm) to die with `Alarm clock' but this
is difficult to deal with given the current structure of the xs Python
lowlevel interface, which doesn't provide a timeout on the call to
wait for a xenstore watch.

x86: Fix the dom0 booting hang when VT-d is enabled.
Dom0 C/S 593 hooks the pci bus probe and remove function. When
probing a function at booting time, it will first add the device into
Dom0's list through a hypercall, then execute the driver's probe
function. If the probe function fails, another hypercall is called to
remove the device from Dom0's list. But for some RMRR devices, for
example, USB devices, they may still be in use for some operation by
BIOS at booting time. So when removing those kind of devices, we
should still keep the RMRR information.
Also add a small fix for "for_each_rmrr_device".

[XSM][FLASK] Argument handling bugs in XSM:FLASK
Addresses a number of argument handling bugs in the flask_op hypercall
in the XSM:Flask module. Thanks to Rafal Wojtczuk at McAfee for
reporting the issues and Tim Deegan at Citrix for providing an
initial patch.
This patch addresses the following issues:
- bounds checking and validation on input arguments to flask_op
- updated ABI/API, size and cmd are now uint32_t
- updated userspace tools and libraries to account for ABI/API
changes
- implemented all copies using from/to guest, better portability
- implemented upper bounds checking on op->cmd, op->size
- implemented sanity checking on op->size and op->buf
- implemented bit vector for checking from/to usage on op->cmd
