This PR implements flat-file storage for finalized block access lists,
specifically:
* The freezer is extended with the notion of tail groups, allowing
different groups within a single freezer instance to maintain
independent tails, while all tables within the same group remain
tail-aligned.
* The freezer can now dynamically attach new tables to an existing
freezer instance, with both the table head and tail initialized to the
freezer's common head.
* A new freezer table, **bals**, has been added to the chain freezer
with its own dedicated tail group, preserving the flexibility to deploy
a tail-pruning policy different from the main chain data group.
Additionally, the BALs in the key-value store will be migrated to the
freezer instance once they are finalized or there are at least 90K block
confirmations on top acting as a "soft finalization". This freezing
policy is same with all chain segment data.
This pull request is based on #32306 , is the second part for shipping
trienode history.
Specifically, this pull request generalize the existing index mechanism,
making is usable
by both state history and trienode history in the near future.
This pull request preserves the root->ID mappings in the path database
even after the associated state histories are truncated, regardless of
whether the truncation occurs at the head or the tail.
The motivation is to support an additional history type, trienode history.
Since the root->ID mappings are shared between two history instances,
they must not be removed by either one.
As a consequence, the root->ID mappings remain in the database even
after the corresponding histories are pruned. While these mappings may
become dangling, it is safe and cheap to keep them.
Additionally, this pull request enhances validation during historical
reader construction, ensuring that only canonical historical state will be
served.
This is a internal refactoring PR, renaming the history to stateHistory.
It's a pre-requisite PR for merging trienode history, avoid the name
conflict.
