This is a first effort at cleaning up and consolidating all information
about the new service state machine and how conditions control this
state machine.
Also, clarified and added sections for all documents regarding how
services and conditions relate.

Some vendors provide their own Netlink plugin to Finit. This patch
makes it possible to disable the default netlink plugin from being
built. However, even before this patch it was possible to overload
the plugin. This just discards it from being built.

The AC_PLUGIN() could not properly handle if a plugin is to be enabled
by default. This patch adds support for outputting the correct help
text.

Libraries and system headers should be included with <> instead of "".
This makes a great difference for the automatic dependency tracking.

Prune standard configure flags and focus on the most important, whatever
they may be. Mention --disable-inetd and describe how --enable-static
works.

This patch fixes regressions in --enable-static introduced with the
conversion to the GNU configure and build system.
The default link flag to libtool is set to -static-libtool-libs, meaning
not a fully static build -- the C library will still be used as an .so
which is usually what people want -- whereas libite (-lite) and libuEv
are linked statically.

Now that we have a proper GNU configure script there is no such thing as
lightweight, and the respected environment variables are listed at the

This patch corrects a long standing issue with Finit. System initial
bootstrap runlevel must be set to 'S' (0), not the configured fallback
runlevel 'RUNLEVEL', which likely is '2'.
Also, minor cleanup, reduce code duplication.

The new state machine handling is not necessary to export to external

Setting O_NONBLOCK on an inetd server socket may fail, we
must check for this or the event loop may stall and block
Finit completely.

If no console is configured, then the following code gets executed:
int conf_parse_config(void)
{
...
char *fallback = FALLBACK_SHELL;
...
tty_register(fallback);
...
}
int tty_register(char *line)
{
...
cmd = strtok(line, " ");
...
}
FALLBACK_SHELL is constant character array and strtok tries to modify
the first argument, which causes a crash.
