This adds a new tx registration interpretation for HF19+ by repurposing the fields of the registration: - `expiration` becomes `hf_or_expiration`; for "new" registrations it contains the hardfork number (e.g. 19 for HF19), but the data layout on chain doesn't change: essentially we determine whether it's a new registration based on whether the field is <= 255 (interpret as HF) or not (interpret as expiration). Changes in "new" registrations: - stake amounts are atomic OXEN rather than portions. This lets us skip a whole bunch of fiddling around with amounts that was necessary to deal with integer truncation when converting between amounts and portions. - the fee in the registration data is now a value out of 10000 instead of a portion (i.e. value out of 2^64-4). This limits fee precision to a percentage with two decimal places instead of ~17 decimal places. Internally we still convert this to a portion when processing the registration for service_node_states, but this makes the registration itself much simpler and easier to work with (as a human). - HF19+ registrations no longer have an expiry timestamp (though they do depend on the hardfork, so they "expire" whenever the next hard fork). The expiry timestamp was really only there to avoid a registration amount decreasing too much from the dropping staking requirement. - Both types are registration are still permitted for HF19, but because registrations with more than 4 contributors expose bugs in the portion transfer code (that results in registrations become invalid), old-style registrations are still limited to 4 contributors. - HF19 will allow both old and new registrations, so that registrations generated before the HF will still work, and so that we don't break testnet which has various "old" registrations on it.
