Returns:
EINA_TRUE if the download start or EINA_FALSE on failure.

This function starts the download of the URL url and saves it to dst. url must provide the protocol, including 'http://', 'ftp://' or 'file://'. Ecore_File must be compiled with CURL to download using http and ftp protocols. If dst is ill-formed, or if it already exists, the function returns EINA_FALSE. When the download is complete, the callback completion_cb is called and data is passed to it. The status parameter of completion_cb will be filled with the status of the download (200, 404,...). The progress_cb is called during the download operation, each time a packet is received or when CURL wants. It can be used to display the percentage of the downloaded file. Return 0 from this callback, if provided, to continue the operation or anything else to abort the download. The only operations that can be aborted are those with protocol 'http' or 'ftp'. In that case job_ret can be passed to ecore_file_download_abort() to abort that download job. Similarly ecore_file_download_abort_all() can be used to abort all download operations. This function returns EINA_TRUE if the download starts, EINA_FALSE otherwise.
