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.

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.
