Several various fixes are included. Not sure what component of
the system uses this file.

There is one 'abort' added in case a fscanf fails. It may be a
bit too brutal.

This is not absolutely necessary (the processing is ok),
but the warning is annoying.

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

calling the function for FDD case executed code for TDD case.

see issue #177

fix incorrect fss_pusch calculation
fix the incorrrect HARQ-PID checking
remove incorrect checking on downlink DCI HARQ PID value
fix incorrect downlink ACK/NACK feedback procedures in TDD
fix no activating PDSCH decoding when DL-DCI is indicating a downlink retransmission

see issue #176

           2- reset dataTx buff correctly
           3- pucch/pusch power control fix

People are complaining on the mailing list about this.
It's not an error to receive a retransmission.

We have a crash:

Program received signal SIGSEGV, Segmentation fault.

This commit reduces the apparition of the crash, but does not
eliminate it completely.

To be fixed after integration.
