We should not let PID 1 fail on systems where Linux is built without
CONFIG_SYSVIPC, or the libc does not support shmget()/shmat().
This workaround implements a fallback to using calloc() for PID 1,
which means the initctl tool will not work properly. A better fix
would be to refactor the shm implementation to instead have initctl
call Finit using api.c for each svc_t. This has been added to the
TODO file as future work.

The generic term for a non-running service is blocked, but a service may
be blocked for several different reasons. When a user stops a service
with `initctl stop` the intuitive expected output from `initctl show` is
"stopped" not "blocked".
When the user later restarts the service with `initctl start` it may of
course be blocked due to wrong runlevel or a missing condition. As can
be expected from the service's configuration.
The rest of the patch refactors the internal API names a bit to reflect
this change.
