Rename interfaces to bring consistency with previous pid->runtime type
renaming. See PR #106 or 69a403cd original type renaming.
Interfaces that are still in use were renamed with a compatibility
interface. Unused interfaces were fully deprecated for removal.

In many cases, this won't result in a change in the actual policy generated, but if the definitions of macros are changed going forward, the mismatches could cause issues.

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.

This interface is useful when using the 'RUN' option in UDEV rules where udev will be executing a user executable to perform some action. This interface allows a domain transition to occur for the run action.

systemd relabels everything in /dev and /run after loading the policy.
In these directories there is a socket file for udev, /run/udev/control,
which is not allowed to be relabelled from tmpfs_t:
avc: denied { relabelfrom } for pid=1 comm="systemd"
name="control" dev="tmpfs" ino=7027
scontext=system_u:system_r:init_t tcontext=system_u:object_r:tmpfs_t
tclass=sock_file permissive=1
avc: denied { relabelto } for pid=1 comm="systemd" name="control"
dev="tmpfs" ino=7027 scontext=system_u:system_r:init_t
tcontext=system_u:object_r:udev_var_run_t tclass=sock_file
permissive=1
/run/tmpfiles.d directory (used by systemd-tmpfiles service) is also
relabelled.
Put in libx32 subs entries that refer to directories with fc entries.
Allow dpkg_t to transition to dpkg_script_t when it executes bin_t for
dpkg-reconfigure.
Some dontaudit rules for mta processes spawned by mon for notification.
Lots of tiny changes that are obvious.
Recent udev implementations now use /run (actually, /run/udev) for storing
database files, rules and more. Hence, we need to extend existing interfaces to
support searching through the udev_var_run_t location (as most of that was
previously only in device_t and/or etc_t or udev_etc_t)
Next to enhancing the interfaces, we provide additional ones that will be used
by the init script (for udev) which needs to create and support the new
/run/udev locations.

udev_var_run_t is used for managing files in /etc/udev/rules.d as well as other files, including udev pid files. This patch creates a type specifically for rules.d files, and an interface for managing them. It also gives access to this type to initrc_t so that rules can be properly populated during startup. This also fixes a problem on Gentoo where udev rules are NOT properly populated on startup.
