substring function: enhancement and hardening
Now, length can have a negative value -n to denote that the
substring should be build between startpos and the character
-n chars from the end. This is a shortcut for stripping charactes
on "both ends" of the string.

Also, some hardening against invalid startpos and length has
been added.
