CURLOPT_SOCKS5_AUTH: allowed methods for SOCKS5 proxy auth
If libcurl was built with GSS-API support, it unconditionally advertised GSS-API authentication while connecting to a SOCKS5 proxy. This caused problems in environments with improperly configured Kerberos: a stock libcurl failed to connect, despite libcurl built without GSS-API connected fine using username and password. This commit introduces the CURLOPT_SOCKS5_AUTH option to control the allowed methods for SOCKS5 authentication at run time. Note that a new option was preferred over reusing CURLOPT_PROXYAUTH for compatibility reasons because the set of authentication methods allowed by default was different for HTTP and SOCKS5 proxies. Bug: https://curl.haxx.se/mail/lib-2017-01/0005.html Closes https://github.com/curl/curl/pull/1454
