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
