As the LIBCURL_VERSION_NUM check at the top of http.h shows we require
curl >= 7.19.4. This means we can remove previously added ifdef's
needed to support older curl versions.
The CURLAUTH_DIGEST_IE macro conditionally used since [1] was added in
7.19.3 (see CURLOPT_HTTPAUTH(3)).
The CURLOPT_USE_SSL macro used since [2] was added in 7.16.4 (see
CURLOPT_USE_SSL(3)).

2017-02-25)
2. 4bc444eb64 ("Support FTP-over-SSL/TLS for regular FTP", 2013-04-07)

No problem. Here it is. Intended to be placed after your 4/4 since the
commit message references the new error message in http.h.
