- bug fixed in ue and enb tracer: the socket needs to be closed
  in case of restart
- cleanup: fix spacing in T_messages.txt

Summary of changes:
- bug fixes in various places

A better solution has to be found.

Pass the command line arguemnt -vcd to trace all VCD variables
and functions.

 -- balanced (current version): all UE shares the same BW
 -- single-ue : one UE will use the whole requested BW
 -- unbalanced : all but one UE will use a residual 2% of the requested BW
                 the rest of requested BW will be used by one UE

  of error
