Steve Karg 2ecb1a2bc8 Bugfix/mstp extended frames client (#592 )

* Fix routing to a remote network in the router-mstp example.

The net, len and adr fields of remote_dest are not initialized
although they are used by the npdu_encode_pdu function in
case of "Routing to another Router". Thank you, Eugene!

* Fixed handling of received MS/TP extended frames.

mstp_port->DataLength should be set to the actual length of decoded data.

* Fix MSTP_Master_Node_FSM and MSTP_Slave_Node_FSM for extended frames.

BACNET_EXTENDED_DATA frames should be treated the same as
their corresponding BACNET_DATA frames.

* Fixed MSTP COBS frame encoding

cobs_frame_encode writes the encoded data to the
beginning of the buffer, overwriting the frame header.

The frame header is constructed before COBS frame encoding,
so it contains the wrong Frame Type and Data Length.

* Added extended frame client unit test

* Fix router-ipv6 application for remote networks

BACnet Simple Router Demo
=========================

The Simple Router demo connects one BACnet/IP and one BACnet MS/TP network.
The router demo also includes a BBMD so that Foreign Device Registration can
be used to tunnel local command line demos to BACnet/IP and BACnet MS/TP
networks.

Configuration
=============

It uses environment variables to configure
the MS/TP COM port and BACnet/IP address on Windows:

set BACNET_IFACE=192.168.0.1
set BACNET_MSTP_IFACE=COM1
set BACNET_MSTP_BAUD=38400
set BACNET_MSTP_MAC=99

It uses environment variables to configure
the MS/TP COM port and BACnet/IP address on Linux:

export BACNET_IFACE=eth0
export BACNET_MSTP_IFACE=/dev/ttyUSB0
export BACNET_MSTP_BAUD=38400
export BACNET_MSTP_MAC=99

Also uses these configurations, but defaults to these values if not set:
set BACNET_MAX_INFO_FRAMES=128
set BACNET_MAX_MASTER=127
set BACNET_IP_PORT=47808
set BACNET_IP_NET=1
set BACNET_MSTP_NET=2

Note: NET number must be unique and 1..65534 (never 0 or 65535)

Example Usage
=============
Build the demo applications for BACnet/IP:
$ make
Build the simple router demo:
$ make router-mstp
Configure the router demo:
$ ./bin/router-mstp.sh enp0s3 /dev/ttyUSB0
Run the router demo:
$ ./bin/router-mstp

In another terminal, configure client apps for Foreign Device Registration:
$ ./bin/bvlc.sh 192.168.0.1
$ ./bin/bacwi -1
$ ./bin/bacepics 123
