Alex ConverseandAlex Converse 2f072b55a4 Fix the conversion of AV_SAMPLE_FMT_FLT and _DBL to AV_SAMPLE_FMT_S32. 
(1<<31) is undefined and seems to be evaluated by gcc to -2^31 when
these formulae require 2^31.

These conversions still need fate tests.

Alex ConverseandAlex Converse 187a537904 Convert some undefined 1<<31 shifts into 1U<<31. 
According to ISO 9899:1999 S 6.5.7/4:

The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits
are filled with zeros. If E1 has an unsigned type, the value of the
result is E1× 2^E2, reduced modulo one more than the maximum value
representable in the result type. If E1 has a signed type and
nonnegative value, and E1× 2^E2 is representable in the result type, then
that is the resulting value; otherwise, the behavior is undefined.

Alex ConverseandAnton Khirnov 9dd94f8379 mov: Add support for zero-sized stsc runs. 
A zero sized stsc run doesn't make a lot of sense but the spec does not
prohibit them and MPlayer VLC demuxers support them.
