Move utility macros from finit.h to helpers.h and continue refactoring
and streamlining of public plugin API.

New function helpers.c:run_getty() refactored from main(). Used to
start a default console getty.
Removed startx finit.conf option, superseded by service statement,
see examples/finit.conf for a working use case.

finit.conf:
Use this as /etc/finit.conf on a Debian 6.0 based system with X
installed and sysklogd instead of rsyslogd. Works.
services:
Alternative method for extending the finit boot procedure. Simply
place this script file in an /etc/finit.d/ directory. The script
uses the standard run-parts tool to chain load other start scripts.
helpers.c:
o New functions:
- run(): home grown system() replacement
- run_interactive(): display progress and status when called
o Bugfix start_process(), make sure to use same signal setup for
children as in run() and run_interactive(). Also, use execvp()
instead of execv() to allow searching $PATH for executables.
finit.h:
o Move signal specific code to new signal.h.
o Bypass verbosity setting to let echo() always print to screen.
finit.c:
o Make run_parts() the default, remove external deps, it works.
o Use run() and run_interactive() to speed up execution further
on embedded systems where forking is expensive.
o Kernel cmdline "quiet" should not close STDIO since this makes
it impossible to run some daemons and start scripts. Instead,
we let "quiet" toggle the finit verbosity setting.
o Remove kernel cmdline "--verbose" (Upstart compat), to be used
to enable verbose finit when kernel should be quiet.
o Setup kernel specific settings in /etc/sysctl.conf
o Fix D-Bus startup problems. Probably what caused X from not
working initially. Silly rabbit.
o Use system() workaround to start X, cannot get it to start
at all using run() or run_interactive() at the moment.
signal.h:
New file, header file for signal.c. Was about time.
signal.c:
Remove blocking of SIGCHLD from sig_setup(), instead we setup
SIGCHLD early in sig_init() to handle fork() in run() & C:o.

finit.c:
o New service and shell_service stanzas for finit.conf
o Run service_startup() before /etc/finit.d/ hooks
o Run service_monitor() at end of startup
helpers.c:
o Several new functions:
- print_desc() displays a service starting up
- print_result() shows if service started OK or not
- start_process() is used by the services framework
svc.c:
Generic API for managing svc_t structures
ipc.o:
TIPC based framework for communicating with the service monitor.
E.g., to relay (re)configuration signals from a Web/CLI
front-end via finit to one or many setup daemons, and back.
services.c:
Service monitor framework
strlcpy.c:
Secure strncpy() replacement from OpenBSD under the free ISC License.

Update license and copyright information details in all files.
Much cleanup by moving hard coded strings/data to #defines and using more
common default values for each such #define.
finit.c:
o Make sdown[], startx[] allocated strings by default NULL
o This fixes the issues where the shutdown handler segfaulted
o Add ability to handle NULL input to build_cmd() by allocating space
o Ignore kernel cmdline "quiet" if in debug mode
o Add support for "network" stanza in finit.conf
o Mount -n to skip removing /etc/mtab
o Call swapon to enable swap if enabled in /etc/fstab
o Cleanup /tmp, /var/run and /var/lock
o Move sig_setup() *after* mount, sig_init() otoh runs early
o Start initctl monitor before forking off startx/getty process
o The startx process is now the console process. Only a getty is
started when in debug mode. Otherwise only X is started if it
is properly setup in /etc/finit.conf
o NOTE: Currently X evdev does not work!
o Support for /usr/sbin/services.sh has been replaced with finit
now instead supporting builtin run-parts for /etc/finit.d/
helpers.c:
o Bug fixes in run_parts() and also added chdir(oldpwd) at bottom.
o New functions:
- getuser() similar to getgroup()
- cls() clear screen, only runs when not in debug mode
- set_procname() used to set name "console" on console process
- set_hostname() encapsulates /etc/hostname and sethostname()
signal.c:
o Split sig_setup() in two: sig_init() and sig_setup()
The former to be called as soon as possible, while latter is
supposed to run when the base filesystem is properly up.
o Remove hard coded distribution specific progress bar write()
o Add debug messages to do_shutdown()
o Remove any lingering sync files in sig_setup()
initctl.c:
o Add debug messages and a new default: case to catch stray runlevels
