This useful, because by ffprobe's very nature, you use it to probe
a file and find out what it is. Requiring every format private option
to be known to the demuxer forces one to run ffprobe twice, if one
wants to use ffprobe in a generic way.
For example, say one wants to probe all user-uploaded files, while
also ignoring edit lists for any MP4s that are uploaded. Currently,
you'd have to run ffprobe twice: once to identify the format, and
once again to actually probe the metadata you want. After this
patch, you could set -ignore_editlist 1 on every call and only
probe once.

Changed to just be the main behavior instead of behind an option,
as Michael suggested.
Didn't really know what would be added to ffprobe.texi, though, since
this is no longer an option.

This only logs the first skipped option. I think it is best if you
iterate through all of them.
