Handle transient UV_EADDRINUSE from uv_tcp_connect() on *BSD

On FreeBSD (and perhaps other *BSD) systems, the TCP connect() call (via uv_tcp_connect()) can fail with transient UV_EADDRINUSE error. The UDP code already handles this by trying three times (is a charm) before giving up. Add a code for the TCP, TCPDNS and TLSDNS layers to also try three times before giving up by calling uv_tcp_connect() from the callback two more time on UV_EADDRINUSE error.
