[PATCH v2 01/14] block: Handle curl 7.55.0, 7.85.0 version changes |
Date: |

From: Anton Johansson <anjo@rev.ng>
* 7.55.0 deprecates CURLINFO_CONTENT_LENGTH_DOWNLOAD in favour of a *_T
version, which returns curl_off_t instead of a double.
* 7.85.0 deprecates CURLOPT_PROTOCOLS and CURLOPT_REDIR_PROTOCOLS in
favour of *_STR variants, specifying the desired protocols via a
string.
