First posted [here](https://github.com/ledgerwatch/erigon/pull/8195)
with bugs, which fixed in this PR.
When we call the debug_traceXXX API provided by Erigon, the withLog
option in tracerConfig is very helpful.
However, currently, the tracer cannot guarantee that the order of logs
output is consistent with the event logs returned in the transaction
receipt. This may make it difficult to use the output of the APIs. If
you need to access event logs in order, it is recommended to use the
event logs returned in the transaction receipt.
Here is an example to illustrate the reason why the order of callTracer
logs and receipt eventlogs can be inconsistent:
In a call trace tree, if a call has multiple logs and this call has
multiple child calls, and logs are also output in the child calls, the
logs of the child calls may be output between the logs of the parent
call in receipt.
I add an index field of log to identify log index of the logs in tracer
result, and it helps me a lot.
Blob transactions are SSZ encoded, so it had to be added to decoding.
There are 2 encoding forms: `network` and `minimal` (usual). Network
encoded blob transactions include "wrapper data" which are `kzgs`,
`blobs` and `proofs`, and decoded by `DecodeWrappedTransaction`. For
previous types of transactions the network encoding is no different.
Execution-payloads / blocks use the minimal encoding of transactions. In
the transaction-pool and local transaction-journal the network encoding
is used.
Concerns:
1. Possible performance reduction caused by these changes, not sure if
streams are better then slices. Go slices in this modifications are
read-only, so they should be referred to the same underlying array and
passed by a reference.
2. If `DecodeWrappedTransaction` and `DecodeTransaction` will create
confusion and should be merged into one function.
In v2.36.0 we correctly trace this transaction, however due to a code
ordering issue in previous releases, there was an 'out of gas' response,
because we fell through to the code here where
ErrContractAddressCollision will be returned as such. This change isn't
the fix, but ensures the actual error is returned.

* core/vm: Define 0xfe opcode as INVALID
* core/vm: Remove opInvalid as opUndefined handles it
