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.

The attribute systemdunit is defined in the file init.te, so interfaces
granting access on it should be defined in init.if

I'm seeing problems on RHEL7 with lvm2-activation-generator that are
coming from recent changes to put systemd-fstab-generator into it's
own domain. I resolved the issues by creaing this generator attribute
to grant common generator permissions and move all generators into
a single systemd_generator_t domain.
Then setup specific types for the following generators:
lvm2-activation-generator - needs to read lvm2 config
systemd-sysv-generator - needs to read stuff in init_t that other generators don't.
systemd-efi-boot-generator - needs to read stuff on the EFI boot partition labeled boot_t
For fstab generator allow it to write /sys

Add interface similar to files_mountpoint() and add a conditional which
allows mount on non_security_file_type.

Update patch to remove init_inherit_rlimit interface and always grant this access for init_t domain (systemd or otherwise). I hope ordering of the new rules is correct.

Create new interface init_rlimit_inherit to allow a process started by init to inherit resource limits. systemd allows for setting of resource limits [1] but the default from SELinux is to not allow the inheritance of those limits as a service is started. This interface allows that resource limit inheritance.
The systemd .service options are LimitCPU=, LimitFSIZE=, LimitDATA=, LimitSTACK=, LimitCORE=, LimitRSS=, LimitNOFILE=, LimitAS=, LimitNPROC=, LimitMEMLOCK=, LimitLOCKS=, LimitSIGPENDING=, LimitMSGQUEUE=, LimitNICE=, LimitRTPRIO=, LimitRTTIME=

Alter interface init_startstop_service to also allow for the status permission. systemctl start <foo> and systemctl stop <foo> work correctly. But systemctl restart <foo> will fail as restart uses status to determine the action to take.
This interface is used by many other modules (like iptables, logging, apache, cron, etc... - see 'admin' interface). This allows restart to work for all these services.

We have a use case on a system where we have a systemd .service unit file that is using the SELinuxContext= [1] option to specify a context for the service being started. The same .service file (/lib/systemd/system/foo@.service) is used to start multiple instances of the same executable that are customized with a different drop-in .conf file for each. The context is customized in /lib/systemd/system/foo@.service file (based on using SELinuxContext=system_u:system_r:foo_%i_t:s0) [2]
We then create /etc/systemd/system/foo@bar.service.d/bar.conf so the final running process is in the domain foo_bar_t
We have created the following interface (in init.if) to meet our needs. The interface is very much like init_daemon_domain except for the use of spec_domtrans_pattern rather than domtrans_pattern because the automatic transition doesn't work in this case.
[1] The SELinuxContext option for systemd is explained https://www.freedesktop.org/software/systemd/man/systemd.exec.html
[2] The systemd %i (and other specifiers) along with drop-in files are explained https://www.freedesktop.org/software/systemd/man/systemd.unit.html

This patch doesn't do everything that is needed to have systemd-nspawn work.
But it does everything that is needed and which I have written in a clear and
uncontroversial way. I think it's best to get this upstream now and then
either have a separate discussion about the more difficult issues, or wait
until I devise a way of solving those problems that's not too hacky.
Who knows, maybe someone else will devise a brilliant solution to the remaining
issues after this is accepted upstream.
Also there's a tiny patch for systemd_machined_t that is required by
systemd_nspawn_t.

I believe that I have addressed all the issues Chris raised, so here's a newer
version of the patch which applies to today's git version.
