Added security for BACnet stack, based on the BACnet 2012 standard, clause 24.
...
Implemented the majority of functionalities presented in the standard, but there are several features that this patch currently lacks:
- Set-Master-Key message has a specific order of key adding and decoding which is not covered
- There is no general secure-apdu-handler function
- Checks for the type of keys used for signing/encryption of specific messages is not implemented
- The status of encrypted flag during the calculation of the signature is ambiguous
There is a Linux implementation using the OpenSSL library, with function prototypes broad enough to allow for different implementations.
Thank you, Nikola Jelić!

Removed check for NPDU Priority on MS/TP outgoing matching messages since the stack currently doesn't support passing the NDPU Priority through, and every outgoing message is NORMAL. This was causing Reply-Postponed, which is not a good thing for high priority messages. Thank you, Ettore Colicchio!

Deprecated Ringbuf_Alloc, and replaced with Ringbuf_Data_Peek() and Ringbuf_Data_Put() functions. Ringbuf_Alloc() was not interrupt or thread safe.

Added Wireshark extcap command line parameter interface to mstpcap utility.
...
Tested with Wireshark on Windows (mostly working).
To use extcap, run Wireshark and go to the About-dialog. Find a tab located there named "Folders". Locate the extcap search path. Copy the mstpcap.exe to that folder, which may not exist.
Restart Wireshark, and look for "BACnet MS/TP on COMx" interfaces.
Configure the interface to change baud rate.
Capture directly from the interface.

Changed the Linux BACnet/IP init to use NetMask.
...
The function was modified to calculate the broadcast address from IP and netmask instead of using SIOCGIFBRDADDR. In some cases it is possible that the ioctl is successful, but the returned address is 0 (e.g. search for Bcast: 0.0.0.0). For some reason in Linux the local loopback device answers from 0.0.0.0 address. So messages broadcast to that address are received from 127.0.0.1 which can possibly create a broadcast loop. This has nothing to do with NAT, but makes the stack more robust. Thank you, Sami Pietikäinen, for the contribution!

Fixed MSTP dropped packets on Linux by fixing usage of ptheads condition variable. Turns out that condition variables cannot be used on their own. They need to be paired with a shared state such as a flag variable protected by a mutex.

While trying to compile mstpsnap, Joe got a compile time failure. Adding fifo.c to the mstpsnap.mak file seems to have resolved GCC's complaint, and mstpsnap seems to be functioning. Thanks, Joe!

Changed Ringbuf API: Ringbuf_Pop_Front is now Ringbuf_Pop, and now it copies the buffer into parameter and returns boolean. Original method was not safe since it returned a pointer to the element but freed the buffer element. Changed Ringbuf_Get_Front to Ringbuf_Peek with no change in functionality, to make names more consistent.
...
Updated all the MS/TP datalink layer implementations that use Ringbuf library.

Returned Tusage_delay to the MS/TP state machines to fix excessive Reply-Posponed messages when received packet is decoupled from immediate handling. Some BACnet routers do not handle Reply-Postponed correctly and drop the subsequent valid reply.
...

Added PDU queue to Linux MS/TP datalink layer.
