Remove legacy 4G kernel modules

Browse Source 
I don't know about any user of the kernel modules. It is effectively
legacy code we carry around, for no good reason. Remove it for the
moment. If we ever need it, we can revert.

This utility allows you to inject packets into the Openair4G stack (UE for the moment) or generate packets
from different parts of the stack.
To compile:
make pt
To get help
./pt --help
Some pregenerated messages (RRC and MAC) can be found in the PACKET_TRACER/messages directory. Here are some
usage examples:
To generate RRC messages (e.g. SIBx)
./pt --eNB_RRC --RRCSIB2_3
./pt --eNB_RRC --RRCConnectionReconfiguration
./pt --UE_RRC --RRCConnectionRequest
To inject packets into the OpenAir4G stack (This works for UE receiver only for now, with control-plane messasges)
./pt --eNB_MAC -I messages/Msg4.txt
./pt -I messages/rrcconnectionsetup.txt -J messages/rrcconnectionreconfiguration.txt --eNB_RRC --RRCConnectionReconfiguration
./pt -I messages/rrcconnectionsetup.txt --eNB_RRC --RRCConnectionSetup
To be done:
- user-plane tests, in particular out-of-order segments to (MAC->RLC)
