Finit <3 did not use GNU configure and build system. This patch adds an
install-dev rule that is used by some to install required headers for
external plugin developers.

Add support for changing the initial hard and soft resource limits for
finit and any processes it launches.
See /etc/finit.conf section in README.md for more information.
When a service changes type from inetd to a regular daemon we must make
sure to first deregister the currently running inetd service properly.
Example: a system boots up with httpd.conf as an inetd service, so Finit
opens a socket 0.0.0.0:80 pending connections to start `httpd -i`.
After a while a user changes httpd.conf to be a regular service and
calls `initctl reload`. Without this patch the socket will remain
open and prevent httpd from opening and binding to the same port.

This patch fixes a problem with lingering inet sockets when inetd
services are removed. When removing an inetd service we must stop
the watcher and close the socket.

We cannot clear the svc_t memory because other applications may have
connected to the same shared memory. An application may be inspecting
the current list of services (initctl) and pulling the rug from under
them could cause some really unpredicatble results.
This reverts commit 06d1e90bac.

Both the original MIT Athena inetd and the GNU inetutils inetd only keep
a backlog of 10 connections in listen() for TCP sockets. This patch
adjusts the Finit hard coded default accordingly.

When starting an inetd service in verbose mode we print a progress
message to the console appended with "Connection". This patch simply
changes that to append with "connection" in lower case.

This patch fixes several issues related to the problem of launching
UDP inetd services:
- Make sure to disable O_NONBLOCK on the socket before passing it to
the inetd service, that's what is expected. This goes for both UDP
and TCP (accepted) connections -- there is no guarantee even for TCP
sockets that they do *not* inherit the parent socket's flags.
- Mark the UDP inetd parent's SVC as busy and stop its watcher before
starting the child task to service the connection. The watcher must
be stopped or multiple child tasks may be spawned!
- Only copy the most relevant parts to the UDP task. In particular
must *not* copy the libuEv watcher data to the task!
- With the child task done and the parent inetd service unblocked we
must restore O_NONBLOCK to the socket before restarting the watcher
When a UDP inetd service connection is handled we create a child task
to service the request, meanwhile we block the parent service. There
was a problem with blocking the parent since we called inetd_stop(),
which both did a shutdown() and close() of the socket ... this patch
introduces separate handling of blocked (busy) inetd services in the
inetd_stop() function and also make sure to handle restarting the
parent watcher in inetd_start() when the child task is done.

Both the new initctl API and the new pidfile watcher plugin failed to
set CLOEXEC on their sockets. This caused forked-off and exec()'d
children to inherit all these descriptors.

Patrick Stewart added the optional `log` keyword to service, run, task
and inetd stanzas in 889bce1. It redirects stdout/stderr to syslog
using the logger tool. This addition to the README is mainly just a
place holder so it's not forgotten before the upcoming README refactor.

Adds an extra 'log' parameter to services that routes STDOUT and STDERR to syslog.
Uses a PTY rather than a pipe, as this prevents log messages hanging around in a buffer indefinitely.
In service_start() the SIGCHLD handler is reenabled before calling complete(), so the service could be reaped by the SIGCHLD handler leaving service_start() waiting forever
Also remove code that duplicates sig_unblock()
The alsa-utils, dbus, lost (PID), resolvconf, and x11-common plugins are
rarely used in the main use-case for Finit (embedded head-less systems).
This patch disables them by default and makes them possible to enable by
configure --enable-$PLUGIN switches.

Slightly more readable code and fix issue with --enable-$PLUGIN not
biting properly in the generated Makefile.

This patch replaces the verbose and kernel-quiet runtime options with
a (hopefully) more useful quiet and silent modes of operation.
By default Finit progressively shows all services it starts at boot, but
when boot has completed and services are started/restarted Finit prints
nothing. If `--disable-quiet` is given all started/restared/stoppping
messages are shown even after boot.
However, if `--enable-silent` is given Finit is completely silent even
at boot, no progress is shown, until the first service is started, which
on most systems is login.

Remove confusing `--with-aix-soname` option to configure. Replace with
hard-coded `aix-soname=both` => shared + static archives are build as to
be expected.
