Fix full tracer forks 1, 2, 3 4, and 5, to generate contract.data only when the value is different from the previous opcode. This reduces the memory usage. This allows getting debug information from batches that use many opcodes and big contract data at the same time. This fix unblocks the processing of one specially problematic batch in Etherscan.
Fix Database::sendData() to simply pretend to have sent the data when config.dbReadOnly = true. Otherwise, it was getting database query errors and retries every 5 seconds.
