fc6a3ef40d audio_mix: fix zeroing output channels in certain cases
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.

3d95d27376 audio_mix: initialize the data pointers to NULL
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.

Originally written by James Almer <jamrial@gmail.com>

With the following contributions by Timothy Gu <timothygu99@gmail.com>

* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
  file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.

157542ebc1 lavr: fix mixing matrix reduction when normalization is disabled
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.

If the matrix reduction ends up with no mixing matrix needed, we need to still
reset the mix function accordingly and log the info to the user.

This is needed if a custom matrix is set by the user after opening the
AVAudioResampleContext because the matrix channel count can change if
different mixing coefficients are used.
