Replaced all 'typeset' and 'typeset -i' calls by 'local', as adviced on:

    https://wiki.ubuntu.com/DashAsBinSh

Went back from making use of the specific Bourne shell construct 'typeset
-i' for easy integer calculations (typeset -i foo=123; foo=foo+456;) to a
more compatible way (local foo=123; foo=$((foo+456)); )

The 'typeset -f' call has been replaced by a call to 'type', effectively
not testing for existence of a declared *function*, but testing for
existence of a declared *something*. You have to sacrifice sometimes in
order to be more portable.
