Changing ArgArray template argument from unsigned to size_t

Browse Source 
Each instantiation of ArgArray template uses sizeof operator, which
returns a std::size_t value. GCC 7.1 warns about invalid conversion
(error: conversion to ‘unsigned int’ from ‘long unsigned
int’ may alter its value [-Werror=conversion]).
