Fixed up prefixLen handling for OS X IPv6 addresses, to a degree.
"Fixed" iptunnel on OS X more.
Fixed comment.
Merge branch 'master' of https://github.com/prurigro/cjdns
Added publictopi6.c for calculating cjdns IP6 addresses from public key, fixed bug in DevUrandomRandomSeed which was only taking sizeof(uintptr_t) bytes of random, made LinuxRandomUuidSysctlRandomSeed work on linux since KERN_RANDOM is an enum.
Updated the tunnel README to include additional details surrounding any issues I had + refactored things a bit to fit the changes
