FATE: add an additional indeo3 test

It is a part of the sample that got broken by recent indeo3 changes.
indeo3: fix off by one in MV validity check

indeo3: use put_pixels instead of put_no_rnd_pixels in copy_cell()

They are the same in this case, except put_pixels also has blocksizes
smaller than 8.
lavc: clear AVBuffers on decoded frames if refcounted_frames is not set

Otherwise some code might mistakenly think it is allowed to unref those
buffers, which would lead to double unref.
vf_split: fix description

It now allows an arbitrary number of inputs, not just two.
af_channelmap: remove now unnecessary goto

Options are freed from the generic code now, there is no need to call
av_opt_free() from the filter.
af_channelmap: ensure the output channel layout is valid.
graphparser: only print filter arguments if they are non-NULL
vf_setpts: cosmetics, reformat
lavfi: add an asetpts filter
lavfi: add trim and atrim filters.
avconv_opt: allocate an OutputFile before the streams.

This way OutputFile variables like recording time can be used when
creating the streams.
