avoptions: Fix av_opt_flag_is_set
...
With the changes in 3b3ea34655
,
"Remove all uses of deprecated AVOptions API", av_opt_flag_is_set
was broken, since it now uses av_opt_find, which doesn't return
named constants unless a unit to look for the constant in is given.
This broke enabling LATM encapsulated AAC output in RTP.

AVOptions: add new API for enumerating children.
...
This will allow the caller to enumerate child contexts in a generic way
and since the API is recursive, it also allows for deeper nesting (e.g.
AVFormatContext->AVIOContext->URLContext)
This will also allow the new setting/reading API to transparently apply
to children contexts.
