dc0d86face AAC: use table for cbrtf(n)*n 
The maximum length of escape_sequence is 21 bits, so adjust limit in
code to match this.

Up to 10% faster on Cortex-A8.

981b8fd777 Don't lock the channel output configuration based on the first value seen for 
non extradata formats. Instead lock it only after the successful decoding of a
frame. This fixes issue 999.

6308765cb5 Ignore subsequent channel configurations after the first in an AAC file. The 
current code doesn't handle them properly, and they are a dubious construction
at best.

7d485f165f Support for getting (i)MDCT output multiplied by a constant scaling factor. 
Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in
'ff_mdct_init' function and slow down initialization a bit.

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

"Google Summer of Code participation" on the mailinglist.
