avcodec_get_context_defaults3() sets only specific options to default the
values.
This commit force all options to be set to the defaults.
This improves effectiveness of new ffm format.
In particular it fixes "bt" option being out of range when context is created
for
non-video media type. (it is 0, when min=1)
