In particular, this commit contains:
* a new abstract class ChannelConditionModel, which provides the base for the
implementation of specific channel condition models. The main method is
GetChannelCondition (mm a, mm b), which determines the channel condition
based on the tx and rx mobility models and returns it as a pointer to an
object of type ChannelCondition
* the implementation of the subclasses ThreeGppRMaChannelConditionModel,
ThreeGppUMaChannelConditionModel, ThreeGppUMiStreetCanyonChannelConditionModel,
ThreeGppIndoorMixedOfficeChannelConditionModel,
ThreeGppIndoorOpenOfficeChannelConditionModel, which inherits from
ChannelConditionModel and statistically determines the LOS/NLOS state based on
the specification in 3GPP TR 38.901
* the implementation of the subclass BuildingsChannelConditionModel, which
inherits from ChannelConditionModel and determines the LOS/NLOS state based
on the buildings deployed in the scenario. It has been adapted from the
mmwave module.
* new classes which extends the PropagationLossModel interface and implements
the pathloss models defined in 3GPP TR 38.901
(ThreeGppRmaPropagationLossModel, ThreeGppUmaPropagationLossModel,
ThreeGppUmiStreeCanyonPropagationLossModel,
ThreeGppIndoorOfficePropagationLossModel). The main method is DoCalcRxPower
(txPow, mm a, mm b), which applies the pathloss model taking into account the
LOS/NLOS channel state and then returns the received power. To retrieve the
channel state, they interface with the class ChannelConditionModel through
the method GetChannelCondition (mm a, mm b)
* documentation and test cases for all the new classes
The LTE/EPC model has been enhanced with new features:
* SGW, PGW and MME are full nodes.
* There are P2P links between core network nodes.
* New S5 interface between SGW and PGW nodes based on GTPv2-C protocol.
* Allow simulations with multiple SGWs and PGWs.
LTE eNB RRC is extended to support:
* S1 signalling with the core network is initiated after the
RRC connection establishment procedure is finished.
* New ATTACH_REQUEST state to wait for finalization of the S1
signalling with the core network.
* New InitialContextSetupRequest primitive of the S1 SAP that is
received by the eNB RRC when the S1 signalling from the core network
is finished.

lte: Split SGW/PGW/MME in different nodes
lte: Add new example
*) Platform was no longer recognized as a attribute of Options. Used waf
Utils call to obtain unversioned platform name.
*) Task classes renamed from <taskname>_task to <taskname>.
Waf was not finding the classes when named with _task suffix.
*) Waf removed check option for 'type_name' check.
Added explicit embedded code snippet based on previous Waf versions to perform uint128 checks.
*) Waf source attribute is now strings, need to convert to nodes to retrieve parent node.
