add portable LIBSSH2_SOCKET_CLOSE() macro

Browse Source 
Add `LIBSSH2_SOCKET_CLOSE()` to the public `libssh2.h` header, for user
code. It translates to `closesocket()` on Windows and `close()` on other
platforms.

Use it in example code.

It makes them more readable by reducing the number of `_WIN32` guards.
