* fix: eth: correctly decode EthGetStorageAt output
We cbor-encode it. Also:
1. Actually use the passed block param.
2. Check if the target actor is an EVM actor to avoid nonsense outputs.
fixes https://github.com/filecoin-project/ref-fvm/issues/1621
1. We do allow deploying with empty initcode.
2. Make sure that the encoded "code" is non-empty, if specified.
Basically, this makes everything consistent (and it's how I specified it
in the FIP).
We now enforce the following rules:
1. No duplicate topics or data.
2. Topics must have 32 byte keys.
3. Topics may not be skipped. (e.g., no t1 & t3 without a t2).
4. Raw codecs.
We _don't_ require that topics/data be emitted in any specific order.
We _skip_ events with unknown keys. We _drop_ events that violate the
above rules.
This:
1. Updates the builtin actors bundle (for actors v10).
2. Updates the event entry type to include the codec.
3. Removes the cbor encoding and zero trimming from event data.
I've chose to:
1. _Not_ add codec handling to the event filtering system for now.
2. _Skip_ events with unexpected codecs.
We don't actually _allow_ these events in the FVM right now, and it
simplifies the implementation.
However, I _am_ recording the codecs in the database so we don't have to
migrate it later.
- Event keys are now t1, t2, t3, t4 for topics; and d for data.
- ref-fvm no longer stores events in the blockstore for us. It just
returns events to the client, who is now responsible for handling
them as it wishes / according to its configuration.
- Add a flag to VMOpts to have the events AMT be written in the blockstore.
- Add a flag to the ChainStore to advertise to the rest of the system
if the ChainStore is storing events.
- Enable that flag if the EthRPC is enabled (can also add an explicit
configuration flag if wanted).
* Refactor: Unify EthTx to FilecoinMessage methods
* Filecoin messages can again be converted to Eth Txs
* All BLS messages should calculated tx hash with unsigned message
* Refactor newEthTxReceipt
* fill in from and to for non-eth transactions
* Hoist nil check out of newEthTxFromMessageLookup
