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.

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.
