Joachim Nilsson 238f63c0d3 Attempt to fix Coverity CID 265222
When reading data from (presumably) initctl over the UNIX domain socket
we might actually be receiving corrupt data from a malicious attacker.

This patch is an attempt at, the very least, guarding against C string
functions reading out of bounds due to non-NULL terminated strings.

Joachim Nilsson c0515d112e New client side API to access svc_t entries without shared memory
This change is one of the required intermediate steps to remove the

programs manipulating the internal memory of PID 1.

Joachim Nilsson 6826d7ee3f Handle event loop watcher failure modes
When alibuEv event watcher callback has `UEV_ERROR` in the events mask
we must handle the error.  Unfortunately, in most cases there is not
much we can do but ignore it or log the error.

Joachim Nilsson 920df09cd5 Fix GCC 7 warning, convert "Fall through" to "fallthrough" comment
In GCC 7 the -Wextra infers the new -Wimplicit-fallthrough which can be
suppressed by adding a simple comment

    /* fallthrough */

Which we had, but was too verbose (and misspelled) for GCC to notice.

Joachim Nilsson 260335a19f Usability, a servivce stopped by a user is stopped, not blocked
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.
