e6c460e3ea swr-test: Use randomized collision free hypercube corner enumeration to select tests. 
This way the user can specify how many or few tests should run while
still providing good coverage over the whole parameter set.

e9b1d5ae5e fix swr_convert buffering of packed audio 
swr_convert is not properly buffering packed input audio when the
output is not large enough, and when resampling is not actually needed
(same samplerate and no SWR_FLAG_RESAMPLE).

buf_set() is only handling the first channel and leaving the others as-is.

Sample program to reproduce the problem is here https://gist.github.com/2431768
