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 patch adresses issue #5. However, there still remains a few issues
to work around before Finit can be built completely standalone.
$ make clean all STATIC=1
LINK finit
helpers.o: In function `getgroup':
helpers.c:(.text+0x10a7): warning: Using 'getgrnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
helpers.o: In function `getuser':
helpers.c:(.text+0x108e): warning: Using 'getpwnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

inetd.c:(.text+0xce): warning: Using 'getservbyname' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
The problem is the NSS plugins and similar issues that prevent static
linking when using the above functions. See issue #5 for more on this.

The ROOTDIR variable was only set in the top-level Makefile,
so when building from a subdirectory the output was slightly
garbled. Moved ROOTDIR declaration to common.mk.

Restructure start by calling the plugin loader earlier. This makes it
possible to run hooks even earlier. This also adds a new hook:
HOOK_ROOTFS_UP which runs as soon as the system root (/) is available.
Another very notable change is the slow refactor of helpers.c into a finit
helper library called libite.so (-lite). This is a light-weight
Also, lots of misc. fixes all over the place. Signal handling still really
needs to be looked into once more!
Makefile:
Add dependency handling for parallell build
Add libite library
ChangeLog:
Update with new 1.4 release. There is a lot of fixes!
libite/:
Collection of utility functions and C library extensions for
finit & its plugins
reboot.c:
New reboot tool. Simply sends SIGINT to PID 1
finit.h:
Cleanup old LISTEN_INITCTL define, code is in an optional plugin now
finit.c:
Let mdev/udev run *after* cls()
Add useful debug statement for /proc/cmdline
Earlier plugin load => new early hook point
Show OK/FAIL for total plugin load, not for each plugin => speedup
helpers.h:
Rename syslog macros to prevent common name clashes (DEBUG/ERROR)
Add __FILE__ to _e(), _d() and _pe() macros
helpers.c:
In ifconfig() the addr and mask arguments are now optional
The copyfile() has been moved to libite.so
Temporarily remove const directive from some functions to build
Use DFLSIG() macro in run_getty() to simplify code
plugin.h:
Add new HOOK_ROOTFS_UP hook
plugin.c:
Fix init_plugins() to actually register the plugin's I/O fd
Skip verbose listing of all plugins in plugin_load_all()
svc.c:
svc_start(): Dito
plugins/Makefile:
Inherit CFLAGS and LDFLAGS, but make sure to filter out -rdynamic
from LDFLAGS, it's used by the daemon, only
plugins/initctl.c:
New includes after helpers.h refactor

- Makefile fixes for installation, paths encoded wrong
- Strip binaries + .so files, support for $(CROSS) toolchain strip
- Default install is now to /sbin/finit and /usr/
- Use the 'plugindir' environemnt variable instead of 'PLUGIN_DIR'

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

Cleanup device creation and initial mount by assuming that the kernel
has devtmpfs enabled. This is the default for most modern GNU/Linux
distributions. See http://lwn.net/Articles/331818/ for more info.
Also, since finit is targeted at deeply embedded systems hooks for the
BusyBox udev replacement, mdev has been added. If MDEV is defined in
the build it will take care of both hotplugging of devices and initial
setup of /dev

This commit is in preparation for importing the Westermo code changes.
Slowly refactoring the finit core into a more modularized unit to be a
bit more maintainable.
