Unlike Posix, Windows handles HANDLE (file, pipe) and SOCKET descriptors
differently. It uses different close(), different errno... So sys_object
was not usable for socket without templating operations to a traits
class.

It's useful to clone std handles when creating streams to write/read to
standard streams. As the stream we give handle to assumes the handle
ownership, it'd close the std handles in stream destructor.

Unfortunately, MSVC cannot deduce template parameters properly where
`const std::basic_string_view<...>` is the parameter. It requires
explicit type cast or explicit template type specification. Which kind
of voids the whole purpose of using std::basic_string_view to make the
client code simpler.

The stdex::sys_info is instantiated for each compilation unit. To reduce
amount of copies, move it to a separate .hpp as system.hpp is almost
always #included.
Breaking-change: Add #include <stdex/sys_info.hpp>

While runtime asserts also served as MSVC Code Analysis hints, the lack
of asserts in Release builds provides no hints to Code Analysis which
rises a lot of warnings then.
Maybe I should learn how to use SAL to annotate <ptr, len> parameter
pairs to allow ptr==nullptr when and only when len==0? 😇

I am aware of the std::filesystem::path::preferred_separator, but we
are targeting C++14 and we need this as a precompiler macro to allow
concatenation of the path strings in precompile stage.

"sys_char" sticks out of "wchar_t", "char32_t", "uint32_t"...
Likewise, "sys_string" out of "string", "wstring", "u16string",
"u32string"...

Windows is very peculiar with #include <windows.h>. Besides we need some
OS primitive wrappers that are OS-specific.
