-------------------------------------

             Summary: allow CURL download into a pipe
                 Key: MESOS-1794
                 URL: https://issues.apache.org/jira/browse/MESOS-1794
             Project: Mesos
          Issue Type: Improvement
          Components: stout
            Reporter: Kamil Domański
            Assignee: Kamil Domański


This divides {{Try<int> net::download(const std::string& url, const std::string& path)}} into three overloads:

# {{Try<int> net::download(const std::string& url, FILE* file)}} downloads a file and sends it to FILE stream
# {{Try<int> net::download(const std::string& url, int fdout)}} opens a file stream based on a file descriptor and calls 1)
# {{Try<int> net::download(const std::string& url, const std::string& path)}} opens a file at _path_ and passes the descriptor to 2), effectively working as before this change

This will allow to download into any file descriptor, such as a pipe, e.g. directly to extraction, as proposed by [~bernd-mesos] in MESOS-1667.
