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...

Manually testing with the Samsung Galaxy Note 4 failed,

add ndi to trace ENB_MAC_UE_DL_SDU

The Msg3 ressource blocks used by random access procedure
were not correctly handled. The MAC scheduler could wrongly
allocate a ressource block for both random access Msg3 and

This hotfix hopefully fixes the problem.

A new function "set_msg3_subframe" has been added in the
interface between PHY and MAC.
