Failures clearly returned from a (SOCKS) proxy now causes this return code. Previously the situation was not very clear as what would be returned and when. In addition: when this error code is returned, an application can use CURLINFO_PROXY_ERROR to query libcurl for the detailed error, which then returns a value from the new 'CURLproxycode' enum. Closes #5770
