net: tools: Helper scripts for running socat, tunslip6 and radvd

Browse source 
Adding convenience scripts that help user when running socat,
radvd and tunslip6 processes. These helper scripts restart
corresponding processes when qemu stops. This way end user
does not need to manual restart the utility processes.

There are also convenience scripts for running socat, radvd and
tunslip6 processes called loop-socat.sh, loop-radvd.sh and
loop-slip.sh. So to simplify things you need three terminals
for doing this:
Terminal 1:
$ ./loop-socat.sh
Terminal 2:
$ sudo ./loop-slip.sh
Terminal 3:
$ sudo ./loop-radvd.sh
After running these scripts you do not need to manual restart
them when qemu process stops.
