Massive cleanup to be able to boot Debian 6.0

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
