50401f5fb7 avcodec: properly check pkt_timebase for validity 
Unset/invalid timebases have a zero numerator.
This makes the checks consistent with other timebase checks and fixes an
integer division by 0.

71af38954b avcodec/on2avc: fix regression on icc since 5495c7f 
Should fix the regression, and also speeds up table generation.
Tables tested on GNU/Linux+clang: they are identical to the ones prior
to 5495c7f. ff_exp10 caused one slight change in one entry, 50000 became
50001 due to somewhat incorrect rounding.

Untested on ICC; passes FATE on GNU/Linux+gcc.

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.
