is introduced, we missed to sync that head file.

No-one (including me) paid attention during review that these
structures don't adhere to the naming requirements of the public
interface: Consistently use xen_ prefixes at least for all new
additions.

The libxc xc_dom_* infrastructure uses a very simple malloc memory pool which
is freed by xc_dom_release. However the various xc_try_*_decode routines (other
than the gzip one) just use plain malloc/realloc and therefore the buffer ends
up leaked.
The memory pool currently supports mmap'd buffers as well as a directly
allocated buffers, however the try decode routines make use of realloc and do
not fit well into this model. Introduce a concept of an external memory block
to the memory pool and provide an interface to register such memory.
The mmap_ptr and mmap_len fields of the memblock tracking struct lose their
mmap_ prefix since they are now also used for external memory blocks.
We are only seeing this now because the gzip decoder doesn't leak and it's only
relatively recently that kernels in the wild have switched to better
compression.

The vGIC will emulate the same version as the hardware. The toolstack has
to retrieve the version of the vGIC in order to be able to create the
corresponding device tree node.
A new DOMCTL has been introduced for ARM to configure the domain. For now
it only allow the toolstack to retrieve the version of vGIC.
This DOMCTL will be extend later to let the user choose the version of the
emulated GIC.

Introduced some new xl commands to enable/disable Cache Monitoring
Technology(CMT) feature.
The following two commands is to attach/detach the CMT feature
to/from a certain domain.
$ xl psr-cmt-attach domid
$ xl psr-cmt-detach domid
This command is to display the CMT information, such as L3 cache
occupancy.
$ xl psr-cmt-show cache_occupancy <domid>

Xen added a new platform_op hypercall for generic MSR access, and this
is the the tool side change to wrapper the hypercall into xc APIs.
For non-preemptible batch resource operations, group them in entries of
xc_resource_op structure. For preemptible ones, use multiple
xc_resource_op structure instead.

[ ijc -- xenctrl.h has moved to tools/libxc/include, adjust patch to match ]
Also moves xc_dom.h to include as it is used often by other xen tools.
Use the new include subdirectories to build Xen tools, qemu-xen and
stubdoms.
Add the old libxc include path to the programs that need it to build,
on a case by case basis and commeting that they shouldn't require
internal libxc headers to build.
[ And: update QEMU_TRADITIONAL_REVISION to corresponding qemu patch
