* format-inl.h(444,1): warning C4804: '>>': unsafe use of type 'bool' in operation
format.h(2808,1): warning C4127: conditional expression is constant
* More fixes for VS2019 pedantic warnings
* Fix "conditional expression is constant" VS2019 warning in more specific way
* Use const_check to silence constexpr warning
* Fix undefined in core-test
Fixes "reference binding to null pointer" in BufferTest.Ctor
buffer.operator[] attempts to return a reference to `buffer.ptr_[0]` when `ptr_`
in `mock_buffer<int> buffer` is null.
* Fix undefined in printf-test
Fixes "signed integer overflow" in PrintfTest.Length
This occurs in `TestLength<long long>("ll")`, since its minimum value minus one
does not fit in long long.
* Fix undefined in printf %0$
Printf counts arguments from 1.
Fixes "shift exponent -4 is negative" in PrintfTest.InvalidArgIndex.
`do_get` is called with index -1 when `basic_printf_context.arg` is called with
id 4294967295 when basic_printf_context::get_arg subtracts 1 from arg_index 0 in
the format string "%0$d".
Refactor `format_specs` and related APIs to support variable-width fill
(#1109), improve naming consistency, remove legacy setters (#940), and
optimize layout.
Mostly equivalent to 'sprintf(const S &format, const Args & ... args)' but generates at most 'n' characters through output iterator 'it'. The output type is the same as with 'format_to_n'.

The iterator class itself and its helpers 'to_pointer' are removed after reformulating the formatting loop in terms of a 'basic_string_view<Char>::iterator'.

* add make_printf_args and make_wprintf_args to printf.h
add minimal test for make_printf_args and make_wprintf_args to printf-test.cc
renamed the old printf_context template to basic_printf_context_t. the original wish was to rename it basic_printf_context, but that clashed with the name of the inner typedef. this style matches the format_context_t struct.
