Initscripts patch.

Initscripts patch.
This changes the order of the shutdown scripts in openslug to ensure
that the network shutdown does not happen before network file systems
have been unmounted.
It also adds some missing scripts - hwclock.sh (load/save the hwclock,
otherwise it gets loaded but not saved, in the absence of NTP).  alignment.sh
(added to openslug, was in 'arm' before), and umountfs (excluded from oe).
The file system unmount scripts use /proc/mounts (not fstab) and unmount in
the correct order (the old scripts only worked if nothing was mounted within
a mounted file system).
Scripts have been patched (openslug only patches) to make them work correctly
with openslug NFS, flash and disk root and to arrange for syslog to run as
long as possible (it's now in S/0/6, not in the user run levels).
Directory struction of openslug-init has been tidied up, with all the
initscripts in a sub-dirctory.
initscritps-openslug is an openslug specific variant of initscripts which
tracks it and fails safe (an update/change to initscripts will cause
initscripts-openslug to fail rather than build strangeness).
turnup also contains a fix for slugbug 150.
