Cedric Roux 8d5901c815 bugfix: fix bug "Unknown UE_id for rnti" 
This bug happens when we detect uplink failure for one UE.
In this case, a DCI format 1A is sent to the UE to ask it
to do random acces.

The way this DCI is generated was not compatible with how
the software is organized. It was expected that the DCI are
added (with add_ue_spec_dci and add_common_dci) in a very
specific order: first all DCIs in common space are added
(with add_common_dci) then all DCIs in UE specific space
are added (with add_ue_spec_dci).

The problem was that the DCI format 1A DCI sent to the UE
for it to do random access is added (with add_ue_spec_dci)
before the DCIs in common space.

That totally messed up the logic in add_common_dci and
add_ue_spec_dci.

The solution is to get rid of Num_common_dci and Num_ue_spec_dci,
replace those two counters by only one (Num_dci) and add
"search_space" in the dci_alloc structure to be used later by
the function "allocate_CCEs" when calling "get_nCCE_offset".

The software had to be adapted to the new variables, everywhere.

I am not sure that the simulators work. It seems that some
of them didn't use Num_common_dci and Num_ue_spec_dci to
decide on what space (common or UE specific) to put the DCI,
but relied on the rnti (comparing with SI_RNTI). To be tested
properly.

The modified simulators are:
  - openair1/SIMULATION/LTE_PHY/dlsim.c
  - openair1/SIMULATION/LTE_PHY/dlsim_tm4.c
  - openair1/SIMULATION/LTE_PHY/dlsim_tm7.c
  - openair1/SIMULATION/LTE_PHY/framegen.c
  - openair1/SIMULATION/LTE_PHY/pdcchsim.c
  - openair1/SIMULATION/LTE_PHY/syncsim.c

Elena_Lukashova 800f66b3d4 Fixing a bug in HARQ for SIC. 
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.

Elena_Lukashova b835f63956 1. There is probably a bug in generate_ue_dlsch_from_dci 
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).
