This patch adds support for a configure script and with it
support for disabling inetd support. See the output from
./configure --help
* Add configure script
* Sprinkle #ifdef fairy dust on svc.c when inetd support is disabled
* Use GCC built-in autodep calculator (-MMD -MP)
* Fix name space issue with include files, use relative paths
* Disable username/group name to uid/gid functions in static builds
* Bug out (error) if a user tries to build the bootmisc plugin static
Possibly fixes GitHub issue #5 and issue #6.
NOTE: The static build has not received any testing at all!

This has been something I wanted to avoid, but then I stumbled so hard
on it myself I simply had to add it. With this commit finit actually
comes of age -- it's now possible to do anything a modern init can --
only faster! :-)
Included in this commit is the OpenBSD version of sys/queue.h, which
unline all versions of the same file on Linux has the _FOREACH_SAFE
macros for iterating over a linked list.
The plugins are now in a TAILQ, loaded in alphabetic order and, unless
the dependency resolver says otherwise, added last in the queue. So,
naming your plugins according to standard sysvinit rules: S01, S02,
etc. takes care of the most basic dependency resolution. When that is
not sufficient, simply add a line ".depends = { "other_plugin",
"another_plugin" }," to your plugin_t definition. Be careful though
for circular dependencies, we don't check for those.

Lots of cleanup and simplification of the main code in this commit.
Most notably libev has been added to take care of the main loop and
monitor services. Still TODO is migrating to use the libev signal
handling.
Convert initctl.c:listen_initctl() to a plugin instead. This also
meant introducing a new form of I/O plugin to finit, also handled
by libev.
Load plugins *after* we've setup the base filesystem (BASEFS) in case
plugins reside on a filesystem not reachable before "mount -a" has run.
This also has the side effect of lining up nicely with the first level
plugin hooks.
If a plugin wants to hook up with a loded service we connect them by
their respective numeric IDs in plugin_register(). I.e., the service
monitor checks if a service has a registered callback, which in turn
decides if a service should be started, stopped or reloaded.
Rip out old EeePC distribution defines from finit.h, none of it really
applies anymore. If you need distribution specific settings this is
the place to put them.
Make hookpoint names (#defines) clearer: after BASEFS, after networking,
after all setup, etc.
Use #inlude_next <signal.h> in signal.h to include system header file!
Simplify service monitor: move essential code to svc.c and rip out
the TIPC dependency. Write your own service.so plugin, or wait for
a more complete example of how to extend service monitoring using
the primitives in svc.c
