Various changes to the Xen userspace policy, including:
- Add gntdev and gntalloc device node labeling.
- Create separate domains for blktap and qemu-dm rather than leaving them in xend_t.
- No need to allow xen userspace to create its own device nodes anymore;
this is handled automatically by the kernel/udev.
- No need to allow xen userspace access to generic raw storage; even if
using dedicated partitions/LVs for disk images, you can just label them
with xen_image_t.
The blktap and qemu-dm domains are stubs and will likely need to be
further expanded, but they should definitely not be left in xend_t. Not
sure if I should try to use qemu_domain_template() instead for qemu-dm,
but I don't see any current users of that template (qemu_t uses
virt_domain_template instead), and qemu-dm has specific interactions
with Xen.
