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
