a247ac640d avcodec: Constify AVCodecs 
Given that the AVCodec.next pointer has now been removed, most of the
AVCodecs are not modified at all any more and can therefore be made
const (as this patch does); the only exceptions are the very few codecs
for external libraries that have a init_static_data callback.

d1f558b362 avcodec/dca: require checked bitstream reader 
Remove half-working attempt at supporting unchecked bitstream reader by
always copying input data into intermediate buffer with large amount of
padding at the end.

Convert LBR decoder to checked bitstream reader. Convert
dcadec_decode_frame() to parse input data directly if possible.

801dbf0269 avcodec/dca: simplify 'residual ok' flag tracking 
Move this from separate structure field to a packet flag.

Behavior should be equivalent, except that residual flag is now properly
cleared when packet has no core frame at all.

Also print a message when forcing recovery mode due to invalid residual
to make debugging easier.

aebf07075f dca: change the core to work with integer coefficients. 
The DCA core decoder converts integer coefficients read from the
bitstream to floats just after reading them (along with dequantization).
All the other steps of the audio reconstruction are done with floats
which makes the output for the DTS lossless extension (XLL)
actually lossy.
This patch changes the DCA core to work with integer coefficients
until QMF. At this point the integer coefficients are converted to floats.
The coefficients for the LFE channel (lfe_data) are not touched.
This is the first step for the really lossless XLL decoding.
