/**
* Filter a list of arrays by removing the ones with an empty() value for some
* index. This function works just like @{function:mfilter}, except that it
* operates on a list of arrays instead of a list of objects.
*
* For example, to remove all arrays without value for key 'username', do this:
*
* ifilter($list, 'username');
*
* The optional third parameter allows you to negate the operation and filter
* out nonempty arrays. To remove all arrays that DO have value for key
* 'username', do this:
*
* ifilter($list, 'username', true);
*
* @param $list array List of arrays to filter.
* @param $index mixed The index.
* @param $negate bool Optionally, pass true to drop arrays
* which pass the filter instead of keeping them.
*
* @return array List of arrays which pass the filter.
* @throws InvalidArgumentException
* @group util
*
* @deprecated
