This adds a new type wrapper that decodes as a list, but does not actually decode the contents of the list. The type parameter exists as a marker, and enables decoding the elements lazily. RawList can also be used for building a list incrementally.
Most uses of the iterator are like this:
it, _ := rlp.NewListIterator(data)
for it.Next() {
do(it.Value())
}
This doesn't require the iterator to be a pointer and it's better to
have it stack-allocated. AFAIK the compiler cannot prove it is OK to
stack-allocate when it is returned as a pointer because the methods of
`Iterator` use pointer receiver and also mutate the object.
The iterator type was not exported until very recently, so I think it is
still OK to change this API.
This is helpful when building a list from already-encoded elements.
This changes `RawList` to ensure the count of items is always valid. Lists with invalid structure, i.e. ones where an element exceeds the size of the container, are now detected during decoding of the `RawList` and thus cannot exist. Also remove `RawList.Empty` since it is now fully redundant, and `Iterator.Count` since it returns incorrect results in the presence of invalid input. There are no callers of these methods (yet).
I removed `Iterator.Count` in #33840, because it appeared to be unused and did not provide the documented invariant: the returned count should always be an upper bound on the number of iterations allowed by `Next`. In order to make `Count` work, the semantics of `CountValues` has to change to return the number of items up and including the invalid one. I have reviewed all callsites of `CountValues` to assess if changing this is safe. There aren't that many, and the only call that doesn't check the error and return is in the trie node parser, `trie.decodeNodeUnsafe`. There, we distinguish the node type based on the number of items, and it previously returned an error for item count zero. In order to avoid any potential issue that could result from this change, I'm adding an error check in that function, though it isn't necessary.
…#33835) This changes the p2p protocol handlers to delay message decoding. It's the first part of a larger change that will delay decoding all the way through message processing. For responses, we delay the decoding until it is confirmed that the response matches an active request and does not exceed its limits. In order to make this work, all messages have been changed to use rlp.RawList instead of a slice of the decoded item type. For block bodies specifically, the decoding has been delayed all the way until after verification of the response hash. The role of p2p/tracker.Tracker changes significantly in this PR. The Tracker's original purpose was to maintain metrics about requests and responses in the peer-to-peer protocols. Each protocol maintained a single global Tracker instance. As of this change, the Tracker is now always active (regardless of metrics collection), and there is a separate instance of it for each peer. Whenever a response arrives, it is first verified that a request exists for it in the tracker. The tracker is also the place where limits are kept.

The heredoc in oss-fuzz.sh writes `#/bin/sh` instead of `#!/bin/sh` as the shebang line of generated fuzz test runner scripts. Without the `!`, the kernel does not recognize the script as having an interpreter directive, causing execution failures on systems that don't fall back to the default shell for shebang-less scripts.
