bc76c46943 aac: Wait to know the channels before allocating frame 
The channel configuration can be delivered only by the PCE,
try to parse it first and not try to decode until a channel
configuration is set.

a188108ebf aac: Support channel configurations 11 and 12 
These are defined in ISO/IEC 14496-3:2009/PDAM 4 for 6.1 and 7.1.
It also defines another 7.1 layout with configuration 14, that one
is not added here for now.

677c804aa3 aac: correctly map 7.1ch-wide AAC from FDK AAC encoder 
FDK AAC encoder outputs SCE(front)+CPE(front)+CPE(back)+CPE(back) on
MODE_7_1_REAR_SURROUND configuration.
Since decoder couldn't properly map 4 back channels, decoding failed
unless -request_channel_layout 0x8000000000000000 has been specified.
Now we treat first CPE(back) as CPE(side) on channel mapping.

0289f81241 aac: Correctly map multichannel ADTS AAC with non-zero channel_config + PCE 
The decoder assigns channels using default channel configuration
for 5.1ch when it parses an ADTS frame header using consecutive
channel ids.

When a PCE comes, it reassigns channels using PCE configuration
using directly the ids provided. They can be arbitrary.

Always use consecutive channel ids to avoid decoding glitches due
spurious reconfigurations due the channel ids mismatch between the
two otherwise-identical channel maps.

87e85a133f aac: Relax reserved_bit validation 
Although the specification mandates this bit to zero, it may happen
that software tools incorrectly flip it to one, invalidating a possibly
valid stream.

Relax this restriction, by failing only when AV_EF_BITSTREAM is set.
This behaviour is similar to aac decoders in Firefox and Quicktime.

462d5e8e6c aacdec: set AVFrame sample_rate 
AVFrame.sample_rate is set in ff_get_buffer, but aacdec calls
ff_get_buffer before the samplerate is known. So it needs to be
set again before returning the frame.
