Only for services that already have a named init script.
Add rules to init_startstop_service(), with conditional arg until
all of refpolicy-contrib callers are updated.
This is to be used where a role needs to start and stop a labeled
service. It centralizes all the rules for redhat < 6 sysvinit that
were used in the _admin interfaces. The rules for other inits will
be added later.
With init_daemon_pid_file supporting class parameters, all calls to
init_daemon_run_dir can now be transformed into init_daemon_pid_file
calls.
Update the init_daemon_run_dir interface so it gives a warning when
used, and use the init_daemon_pid_file interface underlyingly.

For some daemons, it is the init script that is responsible for creating
the PID file of the daemon. As we do not want to update the init SELinux
policy module for each of these situations, we need to introduce an
interface that can be called by the SELinux policy module of the caller
(the daemon domain).
The initial suggestion was to transform the init_daemon_run_dir
interface, which offers a similar approach for directories in /run, into
a class-agnostic interface. Several names have been suggested, such as
init_script_spec_run_content or init_script_generic_run_filetrans_spec,
but in the end init_daemon_pid_file was used.
The interface requires the class(es) on which the file transition should
occur, like so:
init_daemon_pid_file(xdm_var_run_t, dir, "xdm")
init_daemon_pid_file(postgresql_var_run_t, file, "postgresql.pid")

Callers on init_run_daemon() role and domain transition on all
init_script_file_type to system_r and initrc_t respectively.
The old behavior of role and domain transitioning on init daemon entry
files was causing problems with programs that can be run both by system
and session.

Use nscd_use instead of nscd_socket_use. This conditionally allows
nscd_shm_use
Remove the nscd_socket_use from ssh_keygen since it was redundant
already allowed by auth_use_nsswitch
Had to make some ssh_keysign_t rules unconditional else
nscd_use(ssh_keysign_t) would not build (nested booleans) but that does
not matter, the only actual domain transition to ssh_keysign_t is
conditional so the other unconditional ssh_keygen_t rules are
conditional in practice

Due to the introduction of /run, many init scripts need to create the daemon run
dirs (such as /run/udev for the udev init script). To simplify this, we
introduce the "daemonrundir" attribute to which initrc_t has the necessary
create_dirs_perms granted. Because it often needs to change the attributes or
ownership of the directories as well, we also grant the setattr rights on the
directory.
Then, when needed, the modules can call this interface while adding the name of
the directory. This will trigger a named file transition when initrc_t creates
this directory:
init_daemon_run_dir(udev_var_run_t, "udev")
will trigger
files_pid_filetrans(initrc_t, udev_var_run_t, dir, "udev")

Within Gentoo, the init system (openrc) uses a single binary (/sbin/rc)
for all its functions, be it executing init scripts, managing runlevels,
checking state, etc. This binary is not allowed to be labeled
initrc_exec_t as that would trigger domain transitions where this isn't
necessary (or even allowed).
A suggested solution is to use a separate type declaration for /sbin/rc
(rc_exec_t) which transitions where necessary.
This patch includes support for the /sbin/rc rc_exec_t type and declares
the init_rc_exec() interface which allows domains to execute the binary
without transitioning.
