Cedric Roux 5933f21882 hack to avoid zombie UEs in the MAC layer 
Here is the problem:
    Sometimes the UE has no PHY context but
    is still present in the MAC with 'ul_failure_timer' = 0 and
    'ul_out_of_sync' = 0. It seems wrong and the UE stays there forever. Let's
    start an UL out of sync procedure in this case.
    The root cause of this problem has to be found and corrected.
    In the meantime, this hack...

This has to be redone at some point.

Cedric Roux 38b387794e hack in RLC AM to avoid a race 
Here is the problem:
    UE comes. SRB2 is configured via message to RRC.
    At some point the RLC AM is created but not configured yet.
    At this moment (I think) MAC calls mac_rlc_status_ind
    which calls this function. But the init was not finished yet
    and we have a crash below when testing mem_block != NULL.

The "solution" is to test if rlc->input_sdus is NULL.
This is a very dirty hack. I would say the solution
is to use proper locking mechanism because RLC is used
by two threads: PHY/MAC on one hand and RRC on another
hand (I think).

Cedric Roux adbc609bbf bugfix: reset DCI count before adding one 
The management of uplink failure generates a DCI to send
a RA PDCCH order. It calls add_ue_spec_dci which increases
DCI_pdu[CC_id]->Num_ue_spec_dci, but this was reset to 0
*after* the DCI generation. Let's reset *before*.

Bug reported by Liang Yong on openair5g-user mailing list.

Cedric Roux 67e53e72ab fix the use of get_eNB_UE_stats 
The function may return NULL if the UE has been dropped
in the PHY layer but is still present in the MAC layer.

Deal with the NULL case everywhere it's needed.

Cedric Roux ab7a3e8e9c fix compilation of RRH GW 
I am not sure this is the correct solution.

The problem seems to be that the RRH GW does not use ITTI
and thus the type 'as_nas_info_t' is not defined, and then
the compilation fails.

The simple fix is to include 'as_message.h' in
'openair2/RRC/LITE/defs.h' if ENABLE_ITTI is not
defined. Maybe it's not good. RRH GW compiles with this fix.

Cedric Roux 669aa1fbcf fix duplicated definition of boolean_t 
It is defined both in openair2/COMMON/commonDef.h and
openair2/COMMON/platform_types.h.

Removing one or the other definition creates many problems
when compiling this or that part of the system (ue_ip.ko,
at_nas_ue). Let's keep both and protect the definitions
inside #ifdefs.
