ea1136baaf wmadec: require block_align to be set. 
Avoids an infinite loop in the calling programs with decoder not
consuming any input and not returning output.

5959bfaca3 floatdsp: move butterflies_float from dsputil to avfloatdsp. 
This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3)
independent of dsputil.

42d3246948 floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. 
Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed
it from there also.

9d3050d3e9 wma: don't return 0 on invalid packets. 
Return 0 means "please return the same data again", i.e. it causes an
infinite loop. Instead, return an error.

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.
