Now the llrs after SIC procedure are updated.
In dlsim_tm in case of TB0_active==-1,
the llr were taken from the wrong buffer, and in dlsch_demodulation
the SIC llrs were written into the wrong buffer in the same case.

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.

for DCI format 2. Temporaryly going back to the previous
version of code.
2. Enabling rate adaptation with multiple HARQ rounds.
(no change inside the rounds).

Before that the scaling was aplied in precoder.
Now it is done in sqrt_rho_a and sqrt_rho_b.
For TM4 there still remains 1/sqrt(2) instead of
1/2 both at the transmitter and receievr side.

I doubt the case should happen. If it does, let's print an
error, will ease debugging.

Not sure if necessary, but better do it.

Some of them might not be correctly handled.
I put /* TODO: XXX */ where I didn't know if
the fix was correct.

Modifying some printouts into the file.
