To achieve such, this commit also changes the trunnel declaration to use a union instead of a seperate object for the v1 data. A constant is added for the digest length so we can use it within the SENDME code giving us a single reference. Part of #26288 Signed-off-by: David Goulet <dgoulet@torproject.org>
