This error will never happen, but if it ever does happen, we will at least see it.

* core/vm: move TSTORE,TLOAD to correct opcode nums

* core/vm: cleanup

error message should not be capitalized / consistency

Verkle trees store the code inside the trie. This PR changes the interface to pass the code, as well as the dirty flag to tell the trie package if the code is dirty and needs to be updated. This is a no-op for the MPT and the odr trie.

In all other UDPv4 methods, the deadline is checked first. It seems weird to me that ping is an exception. Deadline comparison is also less resource intensive.

This changes the eth_getProof method implementation to re-encode the requested
storage keys, canonicalizing them in the response. For backwards-compatibility reasons,
go-ethereum accepts non-canonical hex keys. Accepting them is fine, but we should
not mirror invalid inputs into the output.

Closes #27306

This is likely the culprit behind several data corruption issues, e.g. where data has been
written to the freezer, but the deletion from pebble does not go through due to process
crash.

The state availability is checked during the creation of a state reader.

-    In hash-based database, if the specified root node does not exist on disk disk, then
    the state reader won't be created and an error will be returned.

-    In path-based database, if the specified state layer is not available, then the
    state reader won't be created and an error will be returned.

This change also contains a stricter semantics regarding the `Commit` operation: once it has been performed, the trie is no longer usable, and certain operations will return an error. 

EstimateGas repeatedly executes a transaction, performing a binary search with multiple gas prices to determine proper pricing. Each call retrieves a new copy of the state (https://github.com/ethereum/go-ethereum/blob/master/internal/ethapi/api.go#L1017) . Because the pending/latest state can change during the execution of EstimateGas, this can potentially cause strange behavior (as noted here: https://github.com/ethereum/go-ethereum/pull/27502#issue-1761957009).

This PR modifies EstimateGas to retrieve the state once and use a copy of it for every call invocation it does.

his function was added in Go 1.20, but our compatibility target
is Go 1.19.

This removes the feature where top nodes of the proof can be elided.
It was intended to be used by the LES server, to save bandwidth 
when the client had already fetched parts of the state and only needed
some extra nodes to complete the proof. Alas, it never got implemented
in the client.

Package rpc uses cgo to find the maximum UNIX domain socket path 
length. If exceeded, a warning is printed. This is the only use of cgo in this
package. It seems excessive to depend on cgo just for this warning, so
we now hard-code the usual limit for Linux instead.

Fixes #27301, a crash that could occur during txpool reorg handling.

floatingRatio is a constant and always non-zero. So there is no need to
check for == 0.
