2f76476549 lavfi: regroup formats lists in a single structure. 
It will allow to refernce it as a whole without clunky macros.

44bcd6f749 avfilter/af_channelmap: Fix double-free of AVFilterChannelLayouts on error 
The query_formats function of the channelmap filter tries to allocate
a list of channel layouts which on success are attached to more permanent
objects (an AVFilterLink) for storage afterwards. If attaching succeeds,
the link becomes one of the common owners (in this case, the only owner)
of the list. Yet if the list has been successfully attached to the link
and an error happens lateron, the list was manually freed, which is wrong,
because it is owned by its link so that the link's pointer to the list will
become dangling and there will be a double-free/use-after-free when the link
is later cleaned up automatically.

This commit fixes this by removing the custom freeing code; this will
temporarily add a leaking codepath (if attaching the list fails, the list
will leak), but this will be fixed soon by making sure that an
AVFilterChannelLayouts without owner will be automatically freed when
attaching it to an AVFilterLink fails.

924fcac521 lavfi/af_channelmap: fix memory leak 
Recent commits 6aaac24d72 and
3835554bf8 made progress towards cleaning
up usage of the formats API, and in particular fixed possible NULL pointer
dereferences.

This commit addresses the issue of possible resource leaks when some intermediate
call fails.

Tested with valgrind --leak-check=full --show-leak-kinds=all, and manual simulation
of malloc/realloc failures.

Fixes: CID 1338330.

6aaac24d72 avfilter/all: propagate errors of functions from avfilter/formats 
Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM).
This propagates the return values.

All of these were found by using av_warn_unused_result, demonstrating its utility.

Tested with FATE. I am least sure of the changes to avfilter/filtergraph,
since I don't know what/how reduce_format is intended to behave and how it should
react to errors.

Fixes: CID 1325680, 1325679, 1325678.

22ecfcd4c7 af_channelmap: properly set the supported output channel layouts 
The current code expects query_formats() to be called exactly once, it
will leak if it's not called at all (filter initialized, but never
configured or used) or try to read freed memory if it's called more than
once.
