Add a field to the AVBufferSinkParams for a list of accepted
channel counts.
Change the default value for the lists in AVBufferSinkParams
to NULL, to let lavfi fill them with something useful.
The fail_enomem path is unneeded because filters are uninited
on failure.

Some code was copy pasted from muxer, which still
have same comments but unlike encoder they are still
relevant to muxer.

It is a shortcut to set all the params using x264_param_parse,
makes simpler importing settings from other software using x264.
