the argument 'coded_bits_per_codeword' has to be an array in
case of several codewords.

The calling sites have been adapted.

Today, only the first index is used, so calling sites where
'coded_bits_per_codeword' is an integer pass the address
of it. It is expected that 'dump_dlsch2' will check in the
future that there is one or two codewords and only access
'coded_bits_per_codeword[1]' when it's sure there are
really two codewords.

I'm not sure the fixes are correct.
