7a440d626b Optimize on-disk deterministic masternode storage to reduce size of evodb (#3017)
* Implement CompactFull() in CDBWrapper

This allows to compact the whole DB in one go.

* Implement more compact version of CDeterministicMNListDiff

This introduces CDeterministicMNStateDiff which requires to only store
fields on-disk which actually changed.

* Avoid writing mnUniquePropertyMap to disk when storing snapshots

This map can be rebuilt by simply using AddMN for each deserialized MN.

* Implement Serialize/Unserialize in CScript

This allows us to directly use READWRITE() on scripts and removes the need
for the ugly cast to CScriptBase. This commit also changes all Dash specific
uses of CScript to not use the cast.

* Keep track of registeration counts and introduce internalID for masternodes

The "internalId" is simply the number of MNs registered so far when the
new MN is added. It is deterministic and stays the same forever.

* Use internalId as keys in MN list diffs

This reduces the used size on-disk.

* Two simple speedups in MN list diff handling

1. Avoid full compare if dmn or state pointers match in BuildDiff
2. Use std::move when adding diff to listDiff in GetListForBlock

* Implement upgrade code for old CDeterministicMNListDiff format to new format

* Track tipIndex instead of tipHeight/tipBlockHash

* Store and pass around CBlockIndex* instead of block hash and height

This allows us to switch CDeterministicMNManager::GetListForBlock to work
with CBlockIndex.

* Refactor CDeterministicMNManager::GetListForBlock to require CBlockIndex*

Instead of requiring a block hash. This allows us to remove blockHash and
prevBlockHash from CDeterministicMNListDiff without the use of cs_main
locks in GetListForBlock.

* Remove prevBlockHash, blockHash and nHeight from CDeterministicMNListDiff

* Remove access to determinisitcMNManager in CMasternodeMetaMan::ToString()

The deterministic MN manager is not fully initialized yet at the time this
is called, which results in an empty list being returned everytime.

* Better logic to determine if an upgrade is needed

Reuse the "best block" logic to figure out if an upgrade is needed. Also
use it to ensure that older nodes are unable to start after the upgrade
was performed.

* Return null block hash if it was requested with getmnlistdiff

* bump CGovernanceManager::SERIALIZATION_VERSION_STRING

* Check SERIALIZATION_VERSION_STRING before deserializing anything else

* Invoke Clear() before deserializing just to be sure

864856688d Multiple speed optimizations for deterministic MN list handling (#2972)
* Generalize CBLSLazyWrapper so that it can be used of pubkeys and secret keys

* Implement == and != operators for CBLSLazyWrapper

* Implement cached hash for CBLSLazyWrapper

* Use CBLSLazyPublicKey for CDeterministicMNState::pubKeyOperator

* Speed up GetProjectedMNPayees by sorting the MN list by last paid

Instead of updating a temporary list for each projected height and calling
GetMNPayee() on it.

* Cache intermediate lists in GetListForBlock

This avoids re-loading and applying diffs again and again.

* Only update masternode list UI max once every 3 seconds

This avoids updating the UI on every block, which turned out to be very
expensive.

* Fix compilation

* Drop time restrictions for mn list update in ClientModel

They are fully handled by MasternodeList now.

40fd1b1685 Make Consensus::LLMQType serializable and use it in serialized classes
Instead of using uint8_t and explicitely casting between the enum
and uint8_t.

5a3f64310b Deserialize CFinalCommitmentTxPayload instead of CFinalCommitment in TxToJSON (#2510)
* Deserialize CFinalCommitmentTxPayload instead of CFinalCommitment in TxToJSON

* Implement ToJson for CFinalCommitmentTxPayload and use it in TxToJSON

Otherwise the nVersion and nHeight members of it are not shown.

Put height into mined commitments and use it instead of the special handling of quorumVvecHash (#2501)
* Allow to skip sig verification for CFinalCommitment::Verify

* Add CFinalCommitmentTxPayload and CheckLLMQCommitment and use it

As described in https://github.com/dashpay/dips/pull/31 (see discussion).

* Properly ban nodes for invalid commitments

Implement and enforce DIP6 commitments (#2477)
* Add LLMQ parameters to consensus params

* Add DIP6 quorum commitment special TX

* Implement CQuorumBlockProcessor which validates and handles commitments

* Add quorum commitments to new blocks

* Propagate QFCOMMITMENT messages to all nodes

* Allow special transactions in blocks which have no inputs/outputs

But only for TRANSACTION_QUORUM_COMMITMENT for now.

* Add quorum commitments to self-crafted blocks in DIP3 tests

* Add simple fork logic for current testnet

This should avoid a fork on the current testnet. It only applies to the
current chain which activated DIP3 at height 264000 and block
00000048e6e71d4bd90e7c456dcb94683ae832fcad13e1760d8283f7e89f332f.

When we revert the chain to retest the DIP3 deployment, this fork logic
can be removed again.

* Use quorumVvecHash instead of quorumHash to make null commitments unique

Implementation of https://github.com/dashpay/dips/pull/31

* Re-add quorum commitments after pruning mempool selected blocks

* Refactor CQuorumBlockProcessor::ProcessBlock to have less nested if/else statements

Also add BEGIN/END markers for temporary code.

* Add comments/documentation to LLMQParams

* Move code which determines if a commitment is required into IsCommitmentRequired

This should make the code easier to read and also removes some duplication.

The also changes the error types that are possible from 3 to 2 now. Instead
of having "bad-qc-already-mined" and "bad-qc-not-mining-phase", there is
only "bad-qc-not-allowed" now.

* Use new parameter from consensus parames for the temporary fork
