New subject: [PATCH 1/8] winhttp: Use schannel in netconn_secure_connect if OpenSSL is not available

22 Jan 2013

The following patch makes winhttp use schannel instead of OpenSSL for
SSL (HTTPS) connections. It is made to be as minimal change as possible
(but complete enough to replace all OpenSSL functionality) to limit the
scope for potential regressions. Further changes and improvements are
left for later.
It doesn't work here:

../../../tools/runtest -q -P wine -M winhttp.dll -T ../../.. -p winhttp_test.exe.so winhttp.c && touch winhttp.ok
