Beginnings of a TCP_test.c overhaul

[hugbubby]

This will be one of many modifications to the autotests to make their unit tests easier to read and more comprehensive. Obviously this pull request does not conclude the work on this unit test but I like to get a pull request in early to see if my style works for you.

Damnit, what's up I thought I already checked that this built correctly

[hugbubby]

Ah, forgive me, I was unfamiliar with the testing framework you guys used. Probably something I should've checked out before submitting this PR.

    IP_Port ip_port_loopback;
    ip_port_loopback.ip = get_loopback();
    int ret;

Remove this "int ret", instead put it into the loop. Then add "int ret" below, at encrypt_data.

auto_tests/TCP_test.c, line 65 at r2 (raw file):

    ip_port_loopback.ip = get_loopback();
    int ret;
    for(uint8_t i = 0; i < NUM_PORTS; i++)

Space after "for".

auto_tests/TCP_test.c, line 66 at r2 (raw file):

    int ret;
    for(uint8_t i = 0; i < NUM_PORTS; i++)
    {

Put the brace on the same line as the closing parenthesis.

    {
        ip_port_loopback.port = net_htons(ports[i]);
        ret = net_connect(sock, ip_port_loopback);	

Remove trailing whitespace.

        //Leave open one connection for the next test.
        if (i + 1 < NUM_PORTS) {

if (i != 0) has the same effect but is simpler.
