* Supporting ? as a string presentation type.

* Supporting ? as a char presentation type.

* Adding iterator_category to counting_iterator.

The previous fix for this in 4a85db1c was incomplete. The intent was to
mimic what `fopen()` is doing. As per standard[1] `fopen()` also sets
`S_IWGRP` and `S_IWOTH` and lets the umask handle the rest.

It usually generates slower code than manual handling.

* - try fixing the warning "chrono.h:1217:37: warning: conversion from 'std::make_unsigned<long long int>::type' {aka 'long long unsigned int'} to 'size_t' {aka 'unsigned int'} may change value [-Wconversion]" by casting int to size_t (occurs when cross-compiling to Raspberry Pi ARMv7)

* - remove call to to_unsigned() because using static_cast<size_t> is enough
