Added environment variables to enhance BBMD behavior in the example server demo.
...
BACNET_BDT_ADDR_1 - dotted IPv4 address of the BBMD table entry 1..128
BACNET_BDT_PORT_1 - UDP port of the BBMD table entry 1..128 (optional)
BACNET_BDT_MASK_1 - dotted IPv4 mask of the BBMD table
entry 1..128 (optional)
Added environment variable to allow setting of the public NAT address.
BACNET_IP_NAT_ADDR - dotted IPv4 address of the public facing router

[Bug #46 ] Fixed potential buffer overflow in BVLC BACnet/IP forwarded NPDU encoding.

Adds network address translation (NAT) handling to BVLC when the device is BBMD.
...
When the device is behind a NAT enabled IP router, the local subnet is not accessible from the WAN side. This means that the device's local IP address cannot be used by other devices to communicate with it. The router can port forward BACnet packets to one device in the local network, but to do so other devices need to use the global IP for communication. The considerations and limitations for NAT usage are specified in BACnet standard Annex J.7.8. Thank you, Sami Pietikäinen, for the contribution!

Added simple local interface to manage entries in the broadcast distribution table. Using this interface, the BDT can be supplied by local means, e.g. device's local user interface as stated in Annex J.4.4. Thank you, Sami Pietikäinen, for the contribution!

Merged revision(s) 2707 from branches/obvius/bacnet-stack:
...
Fix: As a BBMD, when forwarding NPDU to the local subnet (as an IP broacast)
we omit BVLC header, resulting in corrupt packet.
bvlc_send_mpdu(&dest, &npdu[4 + 6], npdu_len); // bad
bvlc_send_mpdu(&dest, &npdu[0], npdu_len+4+6); // good
Also added some debug_prints. To test, start bacserv, use VTS to add
yourself to the BDT, then send a Who-Is to bacserv as a Forwarded-NPDU.
Will be rebroadcast on local subnet but w/o BVLC header.

Arranged the BBMD functions so that BBMD_ENABLE shrouds all the code used just by implementations which serve as a BBMD device.
...
Left the few for registering as a foreign device in the common code body (no #ifdef around them), and moved them to one area toward the end of the file. (Seemed like too few to justify having their own source code file.) Allow foreign device registration function without requiring BBMD_ENABLE.

Revised BBMD registration functions to return something approximating a goodness value. (Still too happy for invalid BBMDs, but it's a start.)
...
Fixed handling of bacapp_decode_context_data() for some of the more unusual (empty, etc) cases I've seen.
