feat(fw,tests): Add pre.deploy_contract, pre.fund_eoa methods to write tests

[marioevz]

🗒️ Description

This PR adds three methods to the Alloc class that allow more versatility and control over the produced tests, by allowing the tests to be written in a way that the required test contracts deploy address is not known ahead of time.

This is done by creating a pre fixture in the test filler that is added to each test during the fill process.

The test needs to add it as a parameter in the following way:

def test_chainid(state_test: StateTestFiller, pre: Alloc):
    ...

During the test filling process, a new Alloc object is created and passed to the test.

Then, to "request" a contract to be placed in the pre-state, the test needs to call pre.deploy_contract function:

contract_address = pre.deploy_contract(Op.SSTORE(1, Op.CHAINID) + Op.STOP)

And the result of the call is the address of deployment.

Similarly, the test does not assume that the transactions are all sent from the same TestAddress and instead requests for a new EOA:

sender = pre.fund_eoa(1_000_000_000_000_000_000_000)

The returned object contains the private key of a funded account, with the requested funding.

Also, when defining the transaction(s) to be sent during the test, the test does no longer need to specify the nonce, since the sender object contains the starting nonce, and the value is automatically increased when the sender is used as a parameter to create a tx:

tx = Transaction(
        ty=0x0,
        chain_id=0x01,
        to=contract_address,
        gas_limit=100000000,
        gas_price=10,
        sender=sender,
    )

Currently deploy_contract accepts both nonce and address parameters, just for the purpose of verifiying that the updated tests have a 1-to-1 fixture outputs. The merged tests though should not use these parameters.

A new parameter --strict-alloc-mode is introduced in the fill parameter that, when enabled, if a test uses either of these parameters, the test filling procedure fails.

This PR updates all tests in the following folders:

• tests/homestead
• tests/berlin
• tests/byzantium
• tests/constantinople
• tests/frontier
• tests/istanbul
• tests/prague

And up to commit 2aad395 the fixtures produce an exact fixture output as the main branch, but the address and nonce workarounds are removed in commit b267d16 and can be filled using the --strict-alloc-mode parameter.

I'm really loving this and where it's heading.

Regarding the comments below, got a feeling I might have missed the mark about Sender semantics below?

Would def like to spend more time with this code.

Extra comments after updating Shanghai tests respectively.
