Replace all instances of atoi with strtol
atoi doesn't check if the conversion from string to int succeeded
which doesn't allow us to do proper error handling.

We also now make sure that the port argument is a valid port
in addition to being properly converted

/* Messenger test
*
* This program adds a friend and accepts all friend requests with the proper message.
*
* It tries sending a message to the added friend.
*
* If it receives a message from a friend it replies back.
*
*
* This is how I compile it: gcc -O2 -Wall -D VANILLA_NACL -o test ../core/Lossless_UDP.c ../core/network.c ../core/net_crypto.c ../core/Messenger.c ../core/DHT.c ../nacl/build/${HOSTNAME%.*}/lib/amd64/{cpucycles.o,libnacl.a,randombytes.o} Messenger_test.c
*
*
* Command line arguments are the ip, port and public_key of a node (for bootstrapping).
*
* EX: ./test 127.0.0.1 33445 CDCFD319CE3460824B33BE58FD86B8941C9585181D8FBD7C79C5721D7C2E9F7C
*
* Or the argument can be the path to the save file.
*
* EX: ./test Save.bak
