OBUDPST-56: Interface Stats, OBUDPST-57: Multi-key,

OBUDPST-58: Header Checksum

This change addresses the need to always handle interface
byte counters as 64-bit values, regardless of the machine
architecture. It also adds multi-key support for large
deployments and an optional PDU header checksum.
Additionally,...
- Several compiler warnings were cleaned up
- Alerts and warnings are now displayed for invalid
  control and data PDUs (but can also be suppressed)
- The max requestable bandwidth on the client (-B mbps)
  increased from 10000 to 32767
- The 64-bit ntohll/htonll macros were modified to allow
  for big-endian architectures
- A column for lost status feedback was added to export
- The authentication key size increased from 32 to 64
- New ErrorStatus error and warning values were added
- A column for interface Mbps was added to export
- A fix for upstream bw that was not deallocated
