Modulize the multiple UEs experiment (lte-ues).

TODO:
1. UE workload.
2. UE joining/leaving scheduling.
3. Enable monitoring UE.
Enable multiple-ues plotting.

NOT supported: ack flows, rate, rlc monitoring.
Start breaking up .cc and .h
Adding function implementation to .h
Enable UEs separate creation and attaching.

- UEs are created BEFORE the experiment begin (otherwise error).
- Workload installing and UEs attaching is done AFTER the beginning
of experiment (not tested).
Testing for previous commit.

- Applications run after experiment begin do
not send data. Possibly ONLY attaching and application
begin should be done during experiment.
Attaching and apps starting are during experiment.
Ues attached at beginning, starting sending after sometime.

- 1 UE start from 0s to end.
- UEs are all attached at the beginning of experiement.
- After sometime, a group of UEs start sending data.
- Plotting:
	+ Multiple UEs plotting for cwnd, rate.
	+ Burst losses count included..
Enable timeout value (rto) monitoring in linux2.6.26 kernel

- linux-2.6.26/nsc/sim_support.cpp,support.c: add hooks to
get TCP inet_connection_sock's parameters.
- Modify processing scripts to be able to plot rto value.
-	Add trace-fading traces for earfcn 100/18100.
-Get pending variable from inet_connection_soket.
-Plotting for timeout and detailed retrans.
Add plotting sequence # for TCP at RTOs.
Rename scripts
- Plot sequence with dup-ack and ack separately.
- Enable frto option on both server and UE.
Plot 2nd retrans, enable SGW app log, sgw synthetic delay.
