When translating "native" messages to Ethereum transactions, correctly handle parameters:
1. If the message looks like a valid "create external", treat it as a contract creation.
2. If it looks like a valid EVM invocation, decode it as such.
3. Otherwise, ABI-encode the parameters to make them look like a "handle_filecoin_method" call. This
will help chain explorers recognize these messages.
Part of #11355
We need to always use the state-tree from the tipset _after_ the message
executed. If we use any other state-tree, we might not find the address
we're trying to resolve.
This change also has some implication for pending messages: there's no
guarantee we'll be able to generate a 0x-style address for a pending
native message. So, instead of trying, I've removed support for pending
native messages from the Eth API. Messages from EthAccounts will still
work, and native messages will still show up in blocks/traces, they just
won't show up as "pending". Which should affect exactly nobody.
I'm also taking this opportunity to cleanup some edge-cases:
1. Pass contexts where appropriate.
2. Remove all state access from `ethTxHashFromSignedMessage`.
Part of #11355
We added this check as a self-test to make sure that the message indices
in our trace matched up with those in the block. Unfortunately, this
only works for blocks on the main-chain, and breaks tracing of uncle
blocks (and tracing of head).
* chore: eth: move & rename input/output encoding functions
These are shared functions, so I'm moving them to the utils library.
* fix: eth: correctly encode and simplify native input/output encoding
When generating eth traces, we encode "native" message inputs/outputs
to "solidity ABI" by formatting the inputs/outputs the same way we do in
FEVM's "handle_native_method". However, we had quite a few bugs with the
implementation:
1. We were right-aligning 64bit values in 256bit words, instead of
left-aligning (as we should given that these values are big-endian).
2. The return-value encoding wasn't correctly handling lengths.
This patch:
1. Fixes those bugs.
2. Deduplicates the logic (we're doing _basically_ the same thing in
both cases).
3. Removes all error paths (these functions can't fail).
We were computing this based on the max block gas, but this is
incorrect. The new value isn't entirely correct either (we should
probably compute an average of the gas used in each block in the
tipset?), but it's good enough.

All these cases here are actually errors and returning `nil` makes this
hard to debug. We likely returned nil in the past to be "best effort"
but, as far as I can tell, we should only hit these error cases if
something is actually wrong.
part of #11325
After changing in prev commit to use to ethereum addresses the
comparison does not make sense against builtin actors. This
fixes that by storing also the filecoin addresses in each trace
Also renamed filecoin related fields to Filecoin prefix.
Also remove requirement call to InvokeContract needed to come
from a evm actor
Introduce nv21 skeleton for local testing:
