* Remove nProtocolVersion fields from deterministic masternode lists
This field was part of my initial implementation from DIP3. One of the last
changes of DIP3 was then to remove this field, which I did not bring back
into code yet. This commit removes it now.
We use PROTOCOL_VERSION now in cases were compatibility in the the pre-DIP3
list is needed.
* Add type and mode fields in DIP3 special TXs
These were added to DIP3 but not in-code yet.
* Add DMN_PROTO_VERSION
* Use BLS keys for operator keys
* Add "bls generate" RPC to generate BLS keys
* Use unique_ptr to store blsKeyOperator and blsPubKeyOperator
Needed because the Chia BLS library crashes when keys are created before
the library is initialized, even if keys are not used. This is the case here
as we have static instances here.
* Remove unnecessary CheckSignature calls
This seems to be some garbage I left in by mistake.
* Fixed review comments
* Fix rpc help for operator keys
All keys that are used as examples are random. None of the secret keys
belongs to any of the public keys.
* Use .GetHash() instead of ::SerializeHash() for BLS pubkeys in txmempool.cpp
* Rename mapProTxBlsPubKeys to mapProTxBlsPubKeyHashes
