Added security for BACnet stack, based on the BACnet 2012 standard, clause 24.

Browse Source 
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!
