* Improve the firmware upgrade process
The old firmware upgrade process attempted to free up RAM by reusing
the 'upgrade_kill_prep' script which is later used by '/sbin/sysupgrade'.
Unfortuantely this doesn't work as intented. While the script will go about
killing various services, 'procd' just goes and starts them up again using
quite a bit more memory in the process. Instead this script just kills
the various daemons 'no questions asked' and then runs the associated
'/etc/init.d/xxx stop' script to instruct 'procd' not the start them up again.
This gets us to the place the original script was trying to go.
+ A syntax fix in '007' patch (need spaces around the [ .. ])
* Inline the style for the firmware page to avoid sleep before flash
* Minor reliability improvements
* Clear away services even earlier
It was discovered that sysupgrade would exit with an
error when some processes could not be killed. The
wifi interface is brought down to avoid this condition
prior to doing the sysupgrade
