dc58065dfb fdkaacenc: Implement flush function 
The internal fdk encoder always produces 1024 bytes even with no input,
so special care should be taken to not drain it twice.

In preparation of sharing them with the decoder. Iteration of the
channel layouts needs to be changed to use a sentinel element.

41950f2aba fdkaacenc: Add missing SURROUND mappings 
SURROUND is more to spec according to the FIXME comments, so add this.

Also add SIDE for 5 and 5.1 because of ffmpeg compatibility, because the
following pipeline downmixes to mono otherwise:

gst-launch-1.0 audiotestsrc num-buffers=1 ! audio/x-raw, channels=6 !
avenc_ac3 ! avdec_ac3 ! audioconvert ! fdkaacenc ! fakesink -v

Fixes #1327

fdkaacenc: Fix draining with libfdk-aac v2.0.0

when we provide zero input buffers.

52e4a20b4e fdkaacdec: Fix build for fdkaac < 0.1.4 
The fdkaac decoder supports 6.1 / 7.1 channels with downmixer
since v0.1.4. Old versions can use AAC_PCM_OUTPUT_CHANNELS
instead of AAC_PCM_MAX_OUTPUT_CHANNELS.

c5a17000b6 fdkaacdec: Enable 8-channel playback 
The decoder seems to default to 6 channels max, downmixing 7.1 to 5.1.
Disable the channel limit to expose all channels to GStreamer.

In addition, none of the standard configurations use ACT_SIDE channels.
The rear channels of the 7.1 configuration have to be taken from
ACT_BACK. See the table in aacenc_lib.h, reproduced here:

19d34f6b5e fdkaacdec: Use WAV channel mapping instead of interleave setting 
The latter is going away in libfdk-aac 2.0.0. Instead, MPEG-style output
is always non-interleaved and WAV-style output is always interleaved.
Earlier libfdk-aac also defaults interleaving accordingly.

Since our reordering looks at the associated PCE indices instead of the
actual channel order, we're agnostic to the mapping.

ce59031b10 fdkaacenc: fix accessing freed memory 
The buffer data is not always copied in _Fill, and will be
read in _DecodeFrame. We unmap at the end of the function,
whether we get there via failure or early out, and keep a
ref to the buffer to ensure we can use it to unmap the
memory even after _finish_frame is called, as it unrefs
the buffer.

Note that there is an access beyond the allocated buffer,
which is only apparent when playing from souphttpsrc (ie,
not from filesrc). This appears to be a bug in the bit
reading code in libfdkaac AFAICT.
