53f9f9c91b When BitsPerSample tag is not present in TIFF, that means file is
monochrome, so initialize picture before decoding.
This fixes decoding monochrome files produced by lavc TIFF encoder.

ebb651d5f2 Make sure that dv encoder initializes all encoded packet data.
The specification does not say which value to use for unused
parts, so fill all unused bytes with 0xff, which is consistent
with what DV usually uses for reserved or unused parts.

ff00b94e9d WMA: use type punning and unroll loops in decode_exp_vlc()
GCC does stupid things if these assignments are done using floats
directly, so fill the runs using integer operations instead.  Also
unroll the loops since the length is always a multiple of 4.

952e872198 Drop unused args from vector_fmul_add_add, simpify code, and rename
The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively.  This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better
match the new operation.
