Merged TODO.IPv6 with TODO.ipv6 and README.IPv6 with README.ipv6
Prior to this patch were two sets of IPv6 README/TODO files: one from payload
and one from transport patchset. Unfortunately Git on Windows gets very confused
of these files, as they only differ in case. This patch merges these sets into
one.
