* Update constants * Add to transaction SigOpCount * Update mass calculation, and move it from InContext to InIsolation * Update block validation accordingly * Add SigOpCount validation during TransactionInContext * Remove checking of mass vs maxMassAcceptedByBlock from consensusStateManager * Update mining manager with latest changes * Add SigOpCount to MsgTx.Copy() * Fix initTestTransactionAcceptanceDataForClone * Fix all tests in transaction_equal_clone_test.go * Fix TestBlockMass * Fix tests in transactionvalidator package * Add SigOpCount to sighash * Fix TestPruningDepth * Fix problems in libkaspawalelt * Fix integration tests * Fix CalculateSignatureHash tests * Remove remaining places talking about block size * Add sanity check to checkBlockMass to make sure all transactions have their mass filled * always add own sigOpCount to sigHash * Update protowire/rpc.md * Start working on removing any remaining reference to block/tx size * Update rpc transaction verbose data to include mass rather then size * Convert verboseData and block size check to mass * Remove remaining usages of tx size in mempool * Move transactionEstimatedSerializedSize to transactionvalidator * Add PopulateMass to fakeRelayInvsContext * Move PopulateMass to beggining of ValidateAndInsertTransaction + fix in it * Assign mass a new number for backward-compatibility
