libxenstored since git commit 9c89dc95201ffed5fead17b35754bf9440fdbdc0
prefers to use "/dev/xen/xenbus" over the "/proc/xen/xenbus".

Since Xen 4.7, /dev/xen/privcmd is used instead of /proc/xen/privcmd.
Add the device into the policy so `xenstored` can work.

This patch is slightly more involved than just running sed. It also adds
typealias rules and doesn't change the FC entries.
The /dev/apm_bios device doesn't exist on modern systems. I have left that
policy in for the moment on the principle of making one change per patch. But
I might send another patch to remove that as it won't exist with modern
kernels.
When using setfiles to validate file contexts of Debian modular policy
(with DISTRO=debian and MONOLITHIC=n), it fails with:
tmp/all_mods.fc: line 527 is missing fields
tmp/all_mods.fc: line 527 is missing fields
tmp/all_mods.fc: Invalid argument
Here is the content of tmp/all_mods.fc around line 527:
# this is a static /dev dir "backup mount"
# if you want to disable udev, youll have to boot permissive and relabel!
/dev/\.static -d system_u:object_r:device_t
/dev/\.static/dev -d system_u:object_r:device_t
/dev/\.static/dev/(.*)? <<none>>
'
The quote of "you'll" has been eaten by m4 and there is a spurious quote
on the last line, which is reported by setfiles. Fix this by removing
the quote in the comment.
Here is an example of a failed build on Travis-CI:

Some policy modules define file contexts in /bin, /sbin and /lib without
defining similar file contexts in the same directory under /usr.
Add these missing file contexts when there are outside ifdef blocks.
In glibc, the get_nprocs method reads /sys/devices/system/cpu/online, so
we need to grant most domains read access to this file. As we don't want
them to have read access on sysfs_t by default, create a new type
(cpu_online_t) and assign it to the file, and grant domains read access
to the file.
This does require systems to relabel the file upon every boot, something
distributions do in their bootup scripts, as /sys devices don't keep
their context.

Intel® AMT Linux support includes two components that allow interaction
between the Intel® AMT FW and the Linux OS: Intel® MEI (Intel® Management Engine Interface)
driver and LMS (Local Management Service) driver. Intel® MEI driver
allows application to communicate with the FW using host interface,
and LMS driver allows applications to access the Intel® AMT FW via the
local Intel® Management Engine Interface (Intel® MEI).
In addition, Intel has validated a kernel patch to enable
IDE-redirection. This is a community maintained patch, but Intel is
distributing the version used in the validation of the other Intel® AMT
components released here:

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.
