Hendrik Leppkes 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.

Ganesh Ajjanagadde 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.
