Provide a stream interface for Schannel - the native crypto APIs - on Windows. This allows Windows to use the same HTTP transport that all the other platforms use, with its own native crypto. Ultimately this allows us to deprecate WinHTTP and we need not add support for our socket changes in two places (our HTTP stack and the WinHTTP stack).
