53c88355a5 avformat/ftp: Fix for invalid use of av_strtok
By the av_strtok() description:
 * On the first call to av_strtok(), s should point to the string to
 * parse, and the value of saveptr is ignored. In subsequent calls, s
 * should be NULL, and saveptr should be unchanged since the previous
 * call.

6f2e38990c avformat/ftp: slightly rework file retrieval with seeking
- do not require a known file size for seek to work
- read the files till the actual end, do not limit data at the queried file
  size
- fix a bug which causes reading 0 byte files for non-existing files
- properly check the return status of the FTP server at the end of the file
  retrieval

a8ec0685ac avformat/ftp: add AVOptions for authentication
This introduces two new AVOption options for the FTP protocol,
one named ftp-user to supply the username to be used for auth,
one named ftp-password to supply the password to be used for auth.

These are useful for when an API user does not wish to deal with
URL manipulation and percent encoding.

Setting them while also having credentials in the URL will use the
credentials from the URL. The rationale for this is that credentials
embedded in the URL are probably more specific to what the user is
trying to do than anything set by some API user.

db85d11d9d libavformat/ftp: Do not leak memory in routine ftp_features
Setting the pointer to NULL inside both ftp_send_command
and ftp_features is redundant. Generally always setting to
NULL in ftp_send_command seems safer, but throughout the file
that parameter was always passed initialized. So I do it here
too for consistency.

Should fix CID1231988 (RESOURCE_LEAK)
