- add local API `toolx_localtime()` to wrap the banned function
`localtime()`. Used from libcurl, libtests and test servers.
- auto-detect and use `localtime_r()` where available (e.g. Linux).
Also to support multi-threading.
- use `localtime_s()` on Windows. It requires MSVC or mingw-w64 v4+.
Also to support multi-threading.
Use local workaround to also support mingw-w64 v3.
- add `src/toolx` to keep internal APIs used by the curl tool and tests,
but not by libcurl. `toolx_localtime()` is the first API in it.
- replace `localtime()` calls with `toolx_localtime()`.
Except in examples.
- note Windows XP's default `msvcrt.dll` doesn't offer secure CRT APIs.
XP likely needs a newer version of this DLL, or may not run.
- note that `localtime()` mirrors `gmtime()`, with the difference that
`gmtime()`'s internal wrapper lives in curlx.
Also:
- drop redundant `int` casts.
