open from both sides

When receiving a SYN segment in the SYN-SENT state, a SYNACK is
sent instead of a RST.

Added option to run infinite tcp test manually to picoapp

Added stress test for UDP NAT.

1000 sockets are made by a client. Each of these sockets send
the same message 3 times to an echo through the NAT. This tests
the system/NAT port check and the forward/backward NAT translation.

Task #267 - Removed unnecessary exit(1) from picoapp tcpclient.

Task #267 - completed TCP check

Checked tcp implementation of closing with sending events to
socket. Changed picoapp behaviour of tcpclient and tcpecho.
Tcpecho now waits on all data to come in from tcpclient, so
now all data is echoed. Tcpclient will only send data on the
EV_WR call, this reduces the calling frequency of the
socket_write function.

The tests now don't show anymore retransmissions and the whole
data buffer is sent between 2 picoapps.

Note: data loss is possible on the tcpecho side since it discards
data in the callback when it can't write to the socket (full).

Task #227 Improvements to MCAST unit tests + added mcast_dbg

Fixed SUPPORT dependancies

Adjusted read size in picoapp.c

Increased tcp read buffer size from 1400 to 1460 bytes. This is the
