scripts: output renumbered patches in a new directory

When renumbering patches, the original patches get removed and replaced
with the new ones. This can be annoying to loose the original patches.
Fix this by putting the new patchs in a directory of their own.

#!/bin/sh

SKIP_ME="### CT_NG SKIP ME ###"

skip_me=$(($(cat "${0}" |@@grep@@ --binary-files=text -o -b -E "^${SKIP_ME}$" |cut -d : -f 1)+${#SKIP_ME}+1))

dd if="${0}" bs=${skip_me} skip=1 2>/dev/null |bzcat

exit 0

### CT_NG SKIP ME ###
