Add win32 initialization support to curl_global_init() and

curl_global_cleanup().  Update corresponding man pages...

Improve the logic in curl_global_cleanup() and curl_global_init() so that
they are not called twice if the application libraries have been
initialized and make sure to reset the init flags in curl_global_cleanup().
