avformat: add support for url field in AvFormatContext

Since Jan 21, 2018 filename field was deprecated in favor
of `url` which now has no length restrictions.

>From doc/APIChanges:
```
2018-01-28 - ea3672b7d6 - lavf 58.7.100 - avformat.h
  Deprecate AVFormatContext filename field which had limited length, use the
  new dynamically allocated url field instead.
```

The URL field is freed by libavformat in avformat_free_context() in
avformat_CloseMux().
