- Use CURLX_FUNCTION_CAST to suppress a function pointer assignment
warning.
a6bbc87f added lookups of some Windows API functions and then cast them
like `*(FARPROC*)&Curl_funcname = address`. Some versions of gcc warn
about that as breaking strict-aliasing rules so this PR changes those
assignments to use CURLX_FUNCTION_CAST.
