The original code left-shifts negative values, which is undefined
in the C99 specification (the one used during normal FFmpeg compilation).
This change multiplies by (1 << shift), which is functionally equivalent,
but has defined behavior.
With this change, fate-idct8x8 compiled with --fsanitize=undefined works.

mostly not merged as the code is needed for a/vsync drop handling
and what the code does is what is needed, it could maybe be moved
elsewhere or factored somehow but simply removing it would be droping
these features.

this prevents the creation of a packet even though no single sample has ever
been input, which some confusion in the timestamp generation
