Description of your issue, suggested solution and other information

I would like an option that will make youtube-dl skip private videos and not mark them as errors. The rationale behind this is: I want to download a large playlist, with a couple private videos. If I tell youtube-dl to skip errors with -i, if any of the other videos have actual legitimate errors (network issues, server down, etc) then youtube-dl will not retry them. I want youtube-dl to skip only private videos, and infinitely retry all other videos. There is an existing issue that sort of touches on this topic, but the rationale was different, so this is not a duplicate: #1594 - in that issue, the user just wanted to skip private videos and didn't care about other videos getting skipped due to other errors. In this scenario, I want other errors to cause infinite retries. I would like an option such as --skip-inaccessible-videos. The rationale behind the name is that depending on the site you are on, the video might not be accessible to various reasons: it's been made private, you're not in a specific group, you haven't subscribed to a specific user, you're not friends with a user, the video is paid-for, etc. This is in contrast to errors such as network errors, file system errors, etc, i.e. things that can be recovered from by just retrying.
