audio-converter: small API tweaks
...
Pass flags in _converter_new() so that we can configure ourselves
differently depending on some options.
SOURCE_WRITABLE -> IN_WRITABLE because the array is called 'in'

audio-convert: simplify API
...
Simplify the API, we don't need the consumed and produced output
arguments. The caller needs to use the _get_in_frames/get_out_frames API
to check how much input is needed and how much output will be produced.

audioconvert: Pass pointer arrays instead of singleton pointers to gst_audio_converter_samples()

In this specific case it wouldn't cause problems as we only ever access the
first array element, but let's make explicit what is happening here.

optimize this later.

Use AudioInfo in the base audio filter class.
Port elements to new API.
