In C++, globals initialization order accross translation units is not
defined. Accessing a global via a function ensures that it is initialized.
This will be needed for #7638, which will statically initialize change
handlers after the Options object has been initialized.
4 options args are a bit unwieldy, especially when you want
to pass only the first and the last one.
With a struct, there is no need to specify the default values
for the args in between.
Done with the following script:
```ruby
Dir["Source/**/*.{h,c,cc,cpp,hpp}"].each do |path|
v = File.read(path)
next if !v.include?("uint32_t") || v.include?("cstdint")
lines = v.lines
line_num = if lines[2].start_with?(" *")
lines.index { |l| l.start_with?(" */") } + 3
else
3
end
lines.insert(line_num, "#include <cstdint>\n")
File.write(path, lines.join(""))
end
```
then fixed-up manually
1. Use `fmt::format_int` directly instead of parsing a format string.
2. Use `AppendStrView`.
3. Define the varargs versions using fold expressions when available.
4. Add tests.
