[LINUX] netfront: Don't call netif_carrier_off until the device is
fuly allocated.
netif_carrier_off() causes events to be queued on the device so if we
subsequently abort the allocation (e.g. due to lack of grant entries)
then we crash trying to access the now invalid device.

[XEN] Fix dom/sysctl structure alignement.
Versions of gcc up to and including 3.3 appear to ignore
__attribute__((align(x))) when applied to typedefs or to members of
anonymous unions. Workaround this by explicitly aligning each
definition of a 64 bit guest handle.
Tidy up x86_64 compat entry.S a bit.

[XEND] Merge VFB support for PV and HVM guests.
This patch merges the way VFB are represented inside Xend by making
HVM VNC consoles use the VFB as its configuration object.
It preserves the way options are specified through xm but will create
a new VFB device that is used by image.py to put vnc config into
qemu-dm's command line. The parsing is moved into image.py's
parseDeviceModel() rather than in configVNC().
Through the Xen API, you can create a 'console' of protocol 'rfb' and
end up with a VNC console, on both HVM and PV guests. The location of
the connecting port is stored in the location attribute of the console
object. This is updated on each XendDomainInfo.update() if it
changes.
Also fixes missing read of the vnclisten and HVM_boot from the
config when initialised via xm. Makes sure bootable attribute for VBD
is store as an int when making SXP config.

[HVM] Save/restore: save shared-info pfn and re-map it on restore
In the short term this allows us to save the same domain more than once.
Longer-term some more careful shared-info management will be needed.

[HVM] Save/restore: clean up marshalling code
- All entries are now defined as structs and saved/restored
in self-contained operations.
- Save/restore operations are type-safe, to tie each entry's
typecode to a particular struct and its length.
- Save/restore handlers are registered once per host instead of
per domain.
- Detect buffer overrun before it happens and abort.

[TOOLS] Fix foreign header build breakage.
Having both the Xen tree and the tools tree recurse into the foreign
headers directory causes headaches in parallel builds and when
building 32-bit tools + 64 bit Xen in the same tree.
Therefore we cause mk-symlinks to symlink in the foreign headers build
bits and generate a local version of the headers and checker tool.
Only libxc needs to do this since the other tools were actually
picking up the libxc version of the headers anyway so the mk-symlinks
calls can be removed from these components.

[HVM] When guest explicitly modifies the TSC, update platform timers
_after_ updating guest time (since otherwise pt_reset() will get the
old hvm_get_guest_time() and subsequently pt_intr_post() will warp
the TSC back again).
This is the smallest fix for the HVM SMP TSC issues seen on recent
(viz. 2.6.18+) linux HVM kernels, but probably not the best. Cleaner
fix needs more thought.
