The implementation looks up the named service by using
`svc_parse_jobstr`. The callbacks for `svc_parse_jobstr` has been
augmented to accept a user data parameter. For this use case,
a carrier for the actual signal was needed. The address of the
signal parameter is taken and passed on as a `void *`. The
callback then simply deferences it as an int - the signal number.
Due to an unfortunate name clash with the DirectFB project LiTE, the
libite (-lite) project had to change its header namespace from
lite/*.h -> libite/*.h
This patch adds support for the new namepace in Finit, triggered by the
define _LIBITE_LITE, from the .pc file read by pkg-config. This should
only be needed on systems that install libite without the compatibility
symlink lite -> libite/ in the staging include directory.

This patch restores the start of the built-in/bundled watchdogd. It is
tracked in the `wdog` variable and handled as an exception at shutdown.
This is also a follow-up to 7b74c99, ensuring that we only kill/stop the
built-in watchdog, not any external. External ones can register to be
the controlling watchdogd in the system -- Finit is not the arbiter for
singletons, this is up to the system engineer.

No need to zero out whole buffer for strlcat(), or other string check
ops. Also drop a few completely useless memset() calls.

This patch corrects a logical glitch, or design flaw, in initctl. The
'restart FOO' command did not stop+start FOO only send SIGHUP (provided
FOO supports SIGHUP). Hence, a new command 'reload FOO' is introduced,
which does exactly that, and 'restart FOO' now stops and restarts FOO.

Since Linux 2.6.4 the SOCK_SEQPACKET socket type is available for UNIX
domain sockets on Linux. It is intended for; "a sequenced-packet socket
that is connection-oriented, preserves message boundaries, and delivers
messages in the order that they were sent." which sounds like us.

Instead of just walking /run/finit/cond, also show the source of each
condition. The hook and net conditions are hard-coded to init[1] atm.
and unknown conditions are shown as unknown[0].

The SysV API compatibility layer gives too little value to be worth
the effort of maintaining it. Users are encouraged to use the
`initctl` tool instead.

This patch removes the built-in inetd support from Finit. We recommend
using an external inetd instead, e.g. xinetd.
If you liked the feature set our inetd provided; filtering per interface
and port redirection, then please let us know or use the code in this
patch (MIT licensed) to recreate it. We are open to reintroducing it,
but then as a stand-alone daemon like the bundled watchdogd and getty.
So long for now, old friend.

The commands are both unsafe (insecure) and send the wrong message,
that initctl can be used to script conditions. Only plugins are
officially supported to manage conditions.

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.

This change is one of the required intermediate steps to remove the
shared memory store for all svc_t, this in turn to avoid any external
programs manipulating the internal memory of PID 1.

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.

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.
