This function does the low-level work of av_opt_set_from_string()
but can be used when there is no option context or when a generic
handling of unknown keys is needed.
av_opt_set_from_string() is changed to make use of it.
It is similar to av_set_options_string() but accepts a list
of options that can be in shorthand: if the key is omitted
on the first fields, the keys from the shorthand list are
assumed, in order.

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.
Signed-off-by: Martin Storsjö <martin@martin.st>
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.
