Start the rework of the /etc/rc shell script.

General changes:
- apply a similar 'style' as used in the installer scripts
- improve comments to be more to the point, remove where code is obvious
- document usage of functions if they have arguments
- rename variables where it improves readability
- replace really old-school shell code with more contemporary idioms

Changes to stripcom():
- skip empty files (eleminates tests for this before calling stripcom)
- remove {} around the while-loop, feed file directly
- instead of continue if empty and then print, print only if non-empty
- use the safer "print -r --" instead of plain "echo"
- quote "$_line" on output to prevent globbing

Changes to update_limit():
- use {,-cur,-max} instead of "" -cur -max
- eleminate if-block with reverse test and continue
