Change mingw-w64 printf format checks in public curl headers to use `__MINGW_PRINTF_FORMAT` instead of `gnu_printf`. This syncs the format checker with format string macros published via `curl/system.h`. (Also disable format checks for mingw-w64 older than 3.0.0 (2013-09-20) and classic-mingw, which do not support this macro.) This fixes bogus format checker `-Wformat` warnings in 3rd party code using curl format strings with the curl printf functions, when using mingw-w64 7.0.0 (2019-11-10) and older (with GCC, MSVCRT). It also allows to delete two workaounds for this within curl itself: - setting `-D__USE_MINGW_ANSI_STDIO=1` for mingw-w64 via cmake and configure for `docs/examples` and `tests/http/clients`. Ref:c730c8549b#14640 The format check macro is incompatible (depending on mingw-w64 version and configuration) with the C99 `%z` (`size_t`) format string used internally by curl. To work around this problem, override the format check style in curl public headers to use `gnu_printf`. This is compatible with `%z` in all mingw-w64 versions and allows keeping the C99 format strings internally. Also: - lib/ws.c: add missing space to an error message. - docs/examples/ftpgetinfo.c: fix to use standard printf. Ref: #14643 (take 1) Follow-up to3829759bd0#12489 Closes #14703
