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

To be fixed after integration.

 - Problem in DCI NDI : the implementation use 5 HARQ processes, but process 0 NDI never toggled because it was reused on subframe 5 that is not carrying format 1 DCI. Fix -> use 8 harq processes instead of 5.
 - SI scheduled on every subframe 5 (even and odd frames) instead of only on even frames
 - Add DLSCH scheduling on subframe 5 for odd frames
 - change default rballoc from 0x7FFF to 0x1FFFF to support maximum 10MHz throughput

Not sure it's the right thing to do, but this commit
should reduce fake builds.

Use LOG_TRACE instead.

This may need to be refined.

The variable ODD_PARITY is defined at various places,
with different values, causing compilation warnings.

It's wrong to define a variable with different values.

A new variable is created, specific to IMEI case: IMEI_ODD_PARITY.
Maybe ODD_PARITY should also have 0xf as value, and so maybe only
one variable is necessary. To be checked at some point...
