Andre Puschmann cc2d71183e ue,phy,nr: fix race condition when setting UL grant for Msg3 
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.

This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.

Andre Puschmann 483a216bd5 ue,stack: refactor handling of radio bearears in UE stack 
this is a rather large commit that is hard to split because
it touches quite a few components.

It's a preparation patch for adding NR split bearers in the next
step.

We realized that managing RLC and PDCP bearers for both NR and LTE
in the same entity doesn't work. This is because we use the LCID
as a key for all accesses. With NR dual connectivity however we
can have the same LCID active at the same time for both LTE and NR
carriers.

The patch solves that by creating a dedicated NR instance for RLC/PDCP
in the stack. But then the question arises for UL traffic on, e.g. LCID 4
what PDCP instance the GW should use for pushing SDUs. It doesnt' know
that. And in fact it doesn't need to. It just needs to know EPS
bearer IDs. So the next change was to remove the knowledge of what
LCIDs are from the GW. Make is agnostic and only work on EPS bearer IDs.

The handling and mapping between EPS bearer IDs and LCIDs for LTE
or NR (mainly PDCP for pushing data) is done in the Stack because
it has access to both.

The NAS also has a EPS bearer map but only knows about default and
dedicated bearers. It doesn't know on which logical channels they
are transmitted.

Andre Puschmann 7113e55d53 rlc: refactor RLC entity to use smart pointers for holding bearers 
this patch mainly modernizes the bearer creation to use smart pointers.
that allows to simplify the error handling.

ue_stack is changed to match new interface. This commit compiles
but doesn't work.

Andre Puschmann c0be8187c8 rlc interface: convert entire read_pdu() interface to return uint32_t 
we had it returning int but had a bug in using the return value properly,
i.e. handling when -1 was returned in RLC TM.

Thinking about it more, it doesn't make sense to have a negative return
value here anyway. Either the RLC can return a PDU or not. If it can't the
returned lenght is zero.

herlesupreeth 0f06ec0d9c Add feature to provide custom GTP-U (S1) address to be advertised inside S1AP messages 
This feature is useful in scenarios where eNB is behind a NAT and EPC on public cloud
Since eNB's GTP-U can only bind to IP address visible in it's host (usually a private IP beind a NAT), it advertises the same to UE in S1AP message
resulting in traffic from EPC to eNB (DL traffic) not able to reach eNB. This commit solves this issue by providing a means to advertise a different IP address than the one GTP-U UDP socket is bound to.
This IP is usually advertised in InitialContextSetupResponse and E-RABSetupResponse.

In order to make use of this feature, use the following parameter in enb.conf

Example:

gtp_advertise_addr = 213.61.141.82
