a8c104a511 AVOption: add support for dictionary types. 
In order to support metadata being set as an option, it's necessary to be able
to set dictionaries as values.

0b357a8095 AVOptions: do not range check flag options. 
It does not make sense in the vast majority of use cases, no currently
defined AV_OPT_TYPE_FLAGS options in Libav set the range to anything
nontrivial, and many of those get it wrong (the "correct" range is
INT_MIN to INT_MAX so that the builtin constant "all" works).

c7e921a54f avopt: Check whether the object actually has got an AVClass 
AVIOContext has got an av_class member that only gets set if
opening the context using avio_open2, but not if allocating a
custom IO context. A caller that wants to read AVOptions from
an AVIOContext (recursively using AV_OPT_SEARCH_CHILDREN) may
not know if the AVIOContext actually has got a class set or not.

4d67ff8e8e AVOptions: fix using named constants with child contexts. 
The named constant needs to be searched for in the same object on which
the option is set, i.e. target_obj.

bcb8d9eb8f Drop unnecessary 'l' length modifier when printfing double values. 
%f denotes a double argument and 'l' does nothing in this case
according to the C spec.

299234a0a9 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.

641c7afe3c 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.

a726d7fd4e AVOptions: in av_opt_find() don't return named constants unless unit is specified. 
That is, unless the caller explicitly asks for them.

Prevents conflict between e.g. the 'loop' option in img2 demuxer and
'loop' flag in AVCodecContext.
