    l2geth: Add support for system addresses · 962f36e4
    Matthew Slipper authored 
    Adds support for system addresses.

To deploy to a system address, the deployer must either be in the list of hardcoded addresses described in `SystemAddressDeployers`, or be specified via the `SYSTEM_ADDRESS_0_DEPLOYER`/`SYSTEM_ADDRESS_1_DEPLOYER` environment variables. The hardcoded system addresses deployers will always override those placed in the environment, so specifying the `SYSTEM_ADDRESS_*` env vars on mainnet, Kovan, or Goerli is a no-op. The env vars are available primarily for testing purposes.

The contract deployment **must** be the first transaction from the deployment address - i.e., it must have nonce zero.

In order to make the tests work, I had to change the integration tests chain ID to no longer conflict with Goerli. The new integration tests chain ID is `987`.

/**
 * Predeploys are Solidity contracts that are injected into the initial L2 state and provide
 * various useful functions.
 *
 * Notes:
 * 0x42...04 was the address of the OVM_ProxySequencerEntrypoint. This contract is no longer in
 * use and has therefore been removed. We may place a new predeployed contract at this address
 * in the future. See https://github.com/ethereum-optimism/optimism/pull/549 for more info.
