Rewrite entropyRT for removing C++/CX dependant.

[MouriNaruto]

Because I found my library which only uses C++/WinRT and Microsoft's OpenSSL fork rely on some C++/CX's function. So I check the this fork's implementation and modify it.

I rewrite it with pure C for smaller EXE and DLL binaries size and no thrown exceptions. (WRL will throw some exceptions in some cases like HStringReference and we should throw no exception in the pure C projects like OpenSSL.) But I found static library's binary size will 4.8MB bigger than before and I want to know how to reduce.

Hi @MouriNaruto,

Thank you very much for the contribution.

I would not worry about the size of the static lib, but more about the final size of the application that links in the static lib.

@khouzam I see, thank you.
