This makes channel coupling more accurate, increasing quality for stereo
content.  It also simplifies exponent extraction and mantissa quantization
by no longer needing to apply an offset to the exponents.

when writing and pressing q during encoding. Instead, check url_interrupt_cb
at the end.

Note that when a protocol is interrupted by url_interrupt_cb, some data may
be silently discarded: the protocol context is not suitable for anything
anymore.

When decoding latm config, use the corresponding aac context and its
m4ac instead of using NULL and a local variable. This fixes decoding of
audio in MPEG TS from SBTVD (the Brazillian Digital TV Sytem), when
there is no extradata. This is the case when using the decoder with
gst-ffmpeg and a GStreamer mpegts demuxer.
