(1) Fix updating of network revision counter on member change.
...
(2) Go back to timestamp as certificate revision number. This is simpler
and more robust than using the network revision number for this and
forcing network revision fast-forward, which could cause some peers
to fall off the horizon when you don't want them to.

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.

(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.
