Notes:
    v3:
    - Add "-M none" to avoid error:
      "No machine specified, and there is no default"
    
    v2:
    - Fix ipv6 free port allocation
    - Check for IPv4, IPv6, AF_UNIX
    - Use g_mkdtemp() rather than g_file_open_tmp()
    - Use socketpair() in test_stream_fd()
    
    v1: compared to v14 of "qapi: net: add unix socket type support to netdev backend":
    - use IP addresses 127.0.0.1 and ::1 rather than localhost

Wouldn't it be possible to write this without the duplicated qtest_hmp() ? 
Something like this:

#define EXPECT_STATE(q, e, t)                             \
do {                                                      \
     char *resp = NULL;                                    \
     g_test_timer_start();                                 \
     do {                                                  \
         g_free(resp);                                     \
         resp = qtest_hmp(q, "info network");              \
         if (t) {                                          \
             strrchr(resp, t)[0] = 0;                      \
         }                                                 \
         if (g_strequal(resp, e)) {                        \
             break;                                        \
         }                                                 \
     } while (g_test_timer_elapsed() < CONNECTION_TIMEOUT); \
     g_assert_cmpstr(resp, ==, e);                         \
     g_free(resp);                                         \
} while (0)

?

Also matching strings against the output of a HMP command sound very fragile 
- isn't there a way to do this with QMP instead?

No more hard-coded /tmp/ paths, please. We're currently in progress of 
enabling the qtests on Windows, too. Please use g_dir_make_tmp() or 
something similar instead.

Maybe check the return code of g_rmdir(), to make sure that all temporary 
files in the directory have indeed been cleaned up successfully?

OK

No, there is no similar command with QMP. There was a tentative in the past but it has 
never been merged.

If it fails there is nothing we can do, I think it's better to ignore the result.
