This prevents the console from crashing when auto-completing on
a variable or property that is null or undefined.

Fixes #23693

node.Node no longer registers any account manager backends by default,
they need to be registered explicitly.

For ethash-based tests, we actually don't need any accounts in the miner
keystore. Just set the etherbase instead to make mining work. For
clique, the signer account must be in the keystore.

The change also adds interrupt handling in stress tests.

This fixes a data race on worker.current by moving the call to StopPrefetcher
into the main loop.

The commit also contains fixes for two other races in unit tests of unrelated packages.

This ensures that all miner goroutines have exited before stopping the blockchain.

Go 1.17.2 fixes some miscompilation issues on amd64 and a runtime issue with timers.
While the upgrade is not strictly necessary for go-ethereum right now, it is still good
to be up-to-date.

Fixes #23681

After the fix I get the address 0x6d6d02e83c4ced98204e20126acf27e9d87b8af2 for the
tx mentioned in the ticket, which agrees with etherscan.

This change removes misuses of sync.WaitGroup in BlockChain. Before this change,
block insertion modified the WaitGroup counter in order to ensure that Stop would wait
for pending operations to complete. This was racy and could even lead to crashes
if Stop was called at an unfortunate time. The issue is resolved by adding a specialized
'closable' mutex, which prevents chain modifications after stopping while also
synchronizing writers with each other.

This resolves a long-standing TODO. The point of copying the address is
to ensure that all data referenced by types.Transaction is independent of the
data passed into the constructor.

This update includes fixes for the *BSD build and go module vendoring.

This PR adds a method to the debug namespace, to iterate over the blocks and check where we have the roots on disk.

The test did not synchronize with per-case goroutines, and thus didn't notice
that some tests were just hanging. This change adds missing synchronization
and fixes the broken tests.

This PR fixes an issue in traceChain, where the statedb Commit operation was performed asynchronously with dereference-operations agains the underlying trie.Database instance. Due to how the reference counting works within the trie database (where parent count is recursively updated when new parents are added), doing dereferencing in the middle of Commit can cause the refcount to become wrong, leading to an inconsistent state. 

This was fixed by doing Commit/Deref from the same routine.

This PR implements a new debug method, which I've talked briefly about to some other client developers. It allows the caller to obtain the intermediate state roots for a block (which might be either a canon block or a 'bad' block).
