Increase maximum packet fragments to make room for huge multicasts with certificates of membership tagged onto them. This likely will not actually increase the number of fragments in practice much, since these are then subsequently compressed.

Version 0.4.3 (the real one): fix Gentoo ip config failures and crashes
...
This version fixes problems with locating the 'ip' command on Gentoo
and possibly other Linux systems, and a problem that could cause a
crash if EthernetTap was unable to locate one of the commands it
invokes to configure IP information on tap devices.
The code also now builds on Windows. It doesn't run yet, but it's a
step. Windows port is in full swing.
Finally, the multicast rate limit defaults were raised a little. More
testing is needed here, and real world measurments.

Windows compiles! (w/Visual Studio 2012) That's about all it does, but it's a start.

Back off a little on multicast propagation depth. Eventually this will be a network parameter.

Several things:
...
(1) Probable fix for issue #7 and major cleanup of EthernetTap code with consolidation for all unix-like systems and specialization for different flavors only when needed.
(2) Refactor of Buffer<> to make its members private, and Packet to use Buffer's methods exclusively to access them. This improves clarity and means we're no longer lying about Buffer's role in the code's security posture.
(3) Add -fstack-protect to Makefile to bounds check stack variables.

Added creation and periodic update of a file called "status" in the home directory that contains peer link status. Useful for debugging and statistics. Send it SIGHUP to force an update now. Otherwise it updates every 120 seconds.
