[Ns-developers] Review request of refactoring bug 557

[Faker Moatamri]

Hi all,
Here is a series of patches needed to fix the bug 557. Please apply the 
patches in that order on a freshly downloaded version of ns-3-dev.
-Add a virtual function NotifyNewAggregate and call it from the function 
AggregateObject. The call will iterate on the listed chain to notify all 
the objects in the node:

Result: Compiling and testing works
-Moved the internet stack creation to the helper, refactor some 
functions and files and replace some others, implement the 
NotifyNewAggregate in each of the protocols...:
    - Replace SetNscTcp by a more generic function called SetTcp
    - The aggregation between two objects is made by the function 
NotifyNewAggregate implemented by the protocols icmp, tcp,ipv4,...
    - Nsc-tcp-l4 has 2 new functions to set and get the IP stack 
implementation/so library.
    - Moved test code from tcp-socket-impl and udp-socket-impl files to 
tcp-test.cc and udp-test.cc

Result: Not compiling
-Updated the examples to conform with the changes in the internet stack 
helper functioning mode and methods. Basically I changed the calls to 
work with the refactored API.

Result: Not compiling
-Updated the Python bindings to reflect the changes in the 
internet-stack-helper and in the core Object.

Result: Compiling but testing fails
-Updated one python test to make testing works, changed the calls for 
internet stack helper.

Result: Compiling and testing perfectly working :-)
Thank you in advance for reviewing my code
Best regards
