Cedric Roux f116a10de3 hotfix: turbo decoder should not fail if CRC is 0 
The case of a CRC == 0 is legal.

After discussion with Raymond, it is also possible to have all
bits at 0 (and so a CRC==0) if there is no transmission and thus
not much energy.

So this hotfix may introduce new problems (false decoding).

A future work is to handle this case properly by not calling the
turbo decoder if there is not enough energy received.

The problem might manifest itself more in the UE part, especially
when it tries to decode MIB and/or SIB (if I understood correctly).

Cedric Roux 190fc96af4 issue 137 - fix RI bits decoding 
RI bits are present only in some transmission modes.

For aperiodic reporting (the mode we do as of today),
36.213 7.2.1 (release 10) says:

    "RI is only reported for transmission modes 3 and 4,
    as well as transmission modes 8 and 9 with PMI/RI reporting"

This commit activates decoding of RI bits only for transmission
modes 3 and 4. 8 and 9 are not done today (as far as I know).

Cedric Roux b0887a1b85 issue 137 - correct computation of G 
G was wrongly computed in some places, not taking into account
CQI and RI bits. This commit saves the correct value computed
in ulsch_decoding so we can reuse it in ulsch_decoding_data
(and the like).

Only the file openair1/PHY/LTE_TRANSPORT/ulsch_decoding.c has
been checked. If the computation is done somewhere else the
problem might still exist.
