Implementation EHF mechanism, part 4. Previous changes are: - https://github.com/dashpay/dash/pull/4577 - https://github.com/dashpay/dash/pull/5505 - https://github.com/dashpay/dash/pull/5469 ## Issue being fixed or feature implemented Currently MN_RR is activated automatically by soft-fork activation after v20 is activated. It is not flexible enough, because platform may not be released by that time yet or in opposite it can be too long to wait. Also, any signal of EHF requires manual actions from MN owners to sign EHF signal - it is automated here. ## What was done? New spork `SPORK_24_MN_RR_READY`; new EHF manager that sign EHF signals semi-automatically without manual actions; and send transaction with EHF signal when signal is signed to network. Updated rpc `getblockchaininfo` to return information about of EHF activated forks. Fixed function `IsTxSafeForMining` in chainlock's handler to skip transactions without inputs (empty `vin`). ## How Has This Been Tested? Run unit/functional tests. Some tests have been updated due to new way of MN_RR activation: `feature_asset_locks.py`, `feature_mnehf.py`, `feature_llmq_evo.py` and unit test `block_reward_reallocation_tests`. ## Breaking Changes New way of MN_RR activation. ## Checklist: - [x] I have performed a self-review of my own code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have added or updated relevant unit/integration/functional/e2e tests - [ ] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ --------- Co-authored-by: UdjinM6 <UdjinM6@users.noreply.github.com> Co-authored-by: PastaPastaPasta <6443210+PastaPastaPasta@users.noreply.github.com>
