audio_mix: fix zeroing output channels in certain cases
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Specifically, when the corresponding input channel exists and its matrix
column is all-zero (which is necessary for zeroing the output), the
matrix column must be removed from the matrix.
This is not done currently, so the mixing code would end up using
uninitialized pointers from stack.
Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind
This should make it easier to catch problems where some of those
pointers are used uninitialized, since reading from NULL should always
crash, while random numbers from stack can turn out to be valid
pointers, so random memory may be silently overwritten.
Should fix issues compiling lavr's Windows resource file.

In some cases when an input contributes fully to the corresponding
output, other inputs may also contribute to the same output. This is the
case, for example, for the default 5.1 to stereo downmix matrix without
normalization.
