idct8x8: Fix undefined negative shifts
...
The original code left-shifts negative values, which is undefined
in the C99 specification (the one used during normal Libav 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.

Remove explicit filename from Doxygen @file commands.
...
Passing an explicit filename to this command is only necessary if the
