Current inet_ntop prototype is not working well for Visual Studio 15 2017

[Sebastian Pipping]

According to #47 (comment) the current prototype

WINSOCK_API_LINKAGE const char WSAAPI inet_ntop(
               int af, const void *src, char *dst, socklen_t size);

in tool/uriparse.c works well for MinGW but not for Visual Studio. Se we need:

• a) a prototype that works with both
• b) some not-MSVC or MinGW-only guard arround it
