Summary0000025: Review string position code should be size_t to be 64 bits safe
DescriptionWe detected that some variables used to store positons and indexes within std::strings were declared as unsigned or int. While size_t is not defined as int or unsigned anymore in 64bits architectures. So, in those case we should use size_t instead of int or unsigned.

Steps To ReproduceBesides potential but inlikely problems when dealing with big strings, this leads to inmediate trouble when storing and comparing with npos in code like:

unsigned pos = s.rfind(....)
if (pos==std::string::npos) .....

Having size_t more precision the first line will truncate the number and the second one will convert it again to size_t rendering into a different value.
