cmdline: parse numerical options stricter

Browse source 
1 - str2offset() no longer accepts negative numbers since offsets are by

2 - introduced str2unum() for the command line parser that accepts
numericals which are not supposed to be negative, so that it will
properly complain on apparent bad uses and mistakes.
