Joachim Nilsson 65c9e7ebc6 Fix I/O plugin watcher, load plugins earlier to enable a new early hook!
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

Joachim Nilsson b373e199a8 Install fixes, $prefix supported better, strip binaries and .so files
- 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'

Joachim Nilsson 2b2fcb740c Fix installation paths and update README on building, bump version
The installation path for plugins was encoded wrong in the finit binary
if *not* unset, i.e., "prefix=".

Updated the README with information on all build related environment
variables.  Much of it is perhaps only needed for packagers and
distributions.

New version bump, v1.2 already.

Joachim Nilsson 0e02429e75 Convert finit to use libev and fix so plugin ctors runs on dlopen().
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
