core/state: value diff tracking in StateDB ( #27349 )
...
This change makes the StateDB track the state key value diff of a block transition.
We already tracked current account and storage values for the purpose of updating
the state snapshot. With this PR, we now also track the original (pre-transition) values
of accounts and storage slots.

core/state: mark account as dirty when resetObject occurs ( #27339 )
...
This changes the journal logic to mark the state object dirty immediately when it
is reset.
We're mostly adding this change to appease the fuzzer. Marking it dirty immediately
makes no difference in practice because accounts will always be modified by EVM
right after creation.

In `touch` operation, only `touched` filed has been changed. Therefore
in the related undo function, only `touched` field should be reverted.
In addition, whether remove this obj from dirty map should depend on
prevDirty flag.

core/state: implement reverts by journaling all changes
...
This commit replaces the deep-copy based state revert mechanism with a
linear complexity journal. This commit also hides several internal
StateDB methods to limit the number of ways in which calling code can
use the journal incorrectly.
As usual consultation and bug fixes to the initial implementation were
provided by @karalabe, @obscuren and @Arachnid. Thank you!
