Changes to support plymouth working in enforcing
...
plymouth is started very early in the boot process. Looks
like before the SELinux policy is loaded so plymouthd is
running as kernel_t rather than plymouthd_t. Due to this
I needed to allow a few permissions on kernel_t to get
the system to boot.

Label /sys/kernel/ns_last_pid as sysctl_kernel_ns_last_pid_t
...
CRIU can influence the PID of the threads it wants to create.
CRIU uses /proc/sys/kernel/ns_last_pidto tell the kernel which
PID it wants for the next clone().
So it has to write to that file. This feels like a problematic as
it opens up the container writing to all sysctl_kernel_t.
Using new label container_t will just write to
sysctl_kernel_ns_last_pid_t instad writing to more generic
sysctl_kernel_t files.

Separate out udevadm into a new domain
...
This is the update I have made based on suggestions for the previous
patches to add a udev_run interface. This adds the new domain udevadm_t
which is entered from /usr/bin/udevadm.
It seems to meet the needs that I have, but there are some things to
note that are probably important.
1) There are a few systemd services that use udevadm during startup.
I have granted the permisssions that I need based on denials I was
seeing during startup (the machine would fail to start without the
permisions).
2) In the udev.fc file there are other binaries that I don't have on a
RHEL7 box that maybe should also be labeled udevadm_exec_t.
e.g. /usr/bin/udevinfo and /usr/bin/udevsend
But as I don't have those binaries to test, I have not updated the
type of that binary.
3) There are some places that call udev_domtrans that maybe should now
be using udevadm_domtrans - rpm.te, hal.te, hotplug.te. Again,
these are not things that I am using in my current situation and am
unable to test the interactions to know if the change is correct.
Other than that, I think this was a good suggestion to split udevadm
into a different domain.
Only change for v4 is to use stream_connect_pattern as suggested.

Resolve denial while changing password
...
I'm seeing the following denials reading /proc/sys/crypto/fips_enabled
and sending message for logging. This resolves those denials.

Allow additional map permission when reading hwdb
...
I'm seeing a denial for udev to map /etc/udev/hwdb.bin.
This creates and uses a new interface to allow the needed
permission for udev.

Updated from previous to create a new interface.
