Hard code the value of the host parameter to `common.localhostIPv4` in
`server.listen()` and `net.connect()`. This

1. ensures that the client `socket._handle` is not reinitialized during
   connection due to the family autodetection algorithm, preventing
   `parser.consume()` from being called with an invalid `socket._handle`
   parameter.
2. works around an issue in the FreeBSD 12 machine where the stress test
   is run where some sockets get stuck after connection.

The maximum number of parsers in the free list is set to 1000. However
the test does not need to use this maximum. Reduce it to 50.
