curlx/fopen: replace open CRT functions their with _s counterparts (Windows)
- `_wopen`        -> `_wsopen_s`
- `_open`, `open` -> `_sopen_s`
- `_wfopen`       -> `_wfopen_s`
- `fopen`         -> `fopen_s`
- `_wfreopen`     -> `_wfreopen_s`
- `freopen`       -> `freopen_s`

For better error handling and for using the CRT functions recommended
via warnings suppressed by `_CRT_SECURE_NO_WARNINGS`.

Also:
- add missing `freopen_s()` prototype when building with mingw-w64 <5.

- tests/server: replace `open()` in the signal handler with `_sopen_s()`
  on Windows.
- tests/server: reduce scope of a checksrc exception to a single line.
- checksrc: ban replaced functions.
