Yank PROBE stuff since it's not used and was a premature addition to the protocol.

Make EthernetTap creation occur in a background thread in Network since it's a time consuming operation on Windows. This fixes one of the last remaining Windows problems.

Several things:
...
(1) Add a bunch of tedious type casts to eliminate unnecessary compiler warnings on Windows X64 builds.
(2) Some EthernetTap work to integrate Windows custom IOCTL for multicast group lookup (not done quite yet).
(3) Dump some more info in selftest to make sure our Windows path lookup functions are returning sane results.

Fix several things:
...
(1) The changes to path learning in the two previous releases were poorly thought out,
and this version should remedy that by introducing PROBE. This is basically a kind of
ECHO request and is used to authenticate endpoints that are not learned via a valid
request/response pair. Thus we will still passively learn endpoints, but securely.
(2) Turns out there was a security oversight in _doHELLO() that could have permitted...
well... I'm not sure it was exploitable to do anything particularly interesting since
a bad identity would be discarded anyway, but fix it just the same.

Certificate of membership works now... had to fix multicast propagation so COM is pushed with multicast, which makes tremendous sense in retrospect.

Take the 0.6.0 opportunity to add flags to a few protocol verbs and do a bit more cleanup. Also fix it so certificates wont be accepted unless they are newer than existing ones.

Multicast propagation is now working from non-supernodes, and working quite well. Time for some more simulation before 0.5.0!

Each peer now tracks the last time it announced multicast LIKEs independently and does so frequently enough to prevent expires. Also add a multicast debug facility for use on the testnet.

Fix for multicast propagation -- supernodes must always keep propagating. Also fix mac-tap build on new version of Xcode CL tools. Must use old llvm-g++ instead of clang for i686 -mkernel.

Apply multicast rate limits to my own multicasts. Will run locally and on a variety of system types to test the result of this.
