d12b5b2f13 build: Split test programs off into separate files 
This avoids spurious library rebuilds when only the test program
code is changed and simplifies the build system.

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 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.
