- use wmain instead of main when _UNICODE is defined [0]
- define argv_item_t as wchar_t * in this case
- use the curl_multibyte gear to convert the command-line arguments to
  UTF-8

This makes it possible to pass parameters with characters outside of
the current locale on Windows, which is required for some tests, e.g.
the IDN tests. Out of the box, this currently only works with the
Visual Studio project files, which default to Unicode.

Use them only if `_UNICODE` is defined, in which case command-line
arguments have been converted to UTF-8.

Closes curl#3784

It only applies to non-Unicode builds now.
Also merge 5.10 into it as it's effectively a duplicate.

This makes it possible to pass parameters with characters outside of

Since curl_setup.h now makes use of curlx_win32_fopen for Win32
builds with USE_WIN32_LARGE_FILES or USE_WIN32_SMALL_FILES defined,
we need to include the relevant files for tests using fopen,
because the libtest sources are including curl_setup.h
