* add filler accounts to bloat validator and predict failure
* assert no accounts match filler
* cleanup magic numbers
* panic if can't load from snapshot with filler accounts specified
* some renames
* renames
* into_par_iter
* clean filler accts, too
Support using connection pooling and use multiple threads to do Postgres db operations. The performance is improved from 1500 RPS to 40,000 RPS measured during validator start.
Support multiple plugins at the same time.
* Add separate vote processing tpu port
* Add feature to send to tpu vote port
* Add vote rejecting sigverify mode

* banking forward tpu vote
* add tpu vote port to dockerfile and other review changes
* Simplify thread id compare
* fix a test; updated cluster_info ABI change

Summary of Changes
Create a plugin mechanism in the accounts update path so that accounts data can be streamed out to external data stores (be it Kafka or Postgres). The plugin mechanism allows
Data stores of connection strings/credentials to be configured,
Accounts with patterns to be streamed
PostgreSQL implementation of the streaming for different destination stores to be plugged in.
The code comprises 4 major parts:
accountsdb-plugin-intf: defines the plugin interface which concrete plugin should implement.
accountsdb-plugin-manager: manages the load/unload of plugins and provide interfaces which the validator can notify of accounts update to plugins.
accountsdb-plugin-postgres: the concrete plugin implementation for PostgreSQL
The validator integrations: updated streamed right after snapshot restore and after account update from transaction processing or other real updates.
The plugin is optionally loaded on demand by new validator CLI argument -- there is no impact if the plugin is not loaded.
* windows: Make solana-test-validator work
The important changes to get this going on Windows:
* ledger lock needs to be done on a file instead of the directory
* IPC service needs to use the Windows pipe naming scheme
* always disable the JIT
* file logging not possible yet because we can't redirect stderr,
but this will change once env_logger fixes the pipe output target!
* Integrate review feedback
* reimplement rpc pubsub with a broadcast queue
* update tests for new pubsub implementation
* fix: fix review suggestions
* chore(rpc): add additional pubsub metrics
* integrate max subscriptions check into SubscriptionTracker to reduce locking
* separate subscription control from tracker
* limit memory usage of items in pubsub broadcast queue, improve error handling
* add more pubsub metrics
* add final count metrics to pubsub
* add metric for total number of subscriptions
* fix small review suggestions
* remove by_params from SubscriptionTracker and add node_progress_watchers map instead
* add subscription tracker tests
* add metrics for number of pubsub notifications as a counter
* ignore clippy lint in TokenCounter
* fix underflow in token counter
* reduce queue capacity in pubsub tests
* fix(rpc): fix test timeouts
* fix race in account subscription test
* Add RpcSubscriptions::new_for_tests

This is a bugfix.
When `load_frozen_forks()` called `snapshot_bank()`, the accounts hash
was not computed. So then when a snapshot archive was eventually
created, its hash would be all 1s, which is clearly wrong. The fix is
to update the bank's accounts hash before taking the bank snapshot.
Add `--incremental-snapshots` flag to enable incremental snapshots.
This will allow setting `--full-snapshot-interval-slots` and
`--incremental-snapshot-interval-slots`.
Also added `--maximum-incremental-snapshots-to-retain`.

When the validator is waiting to restart, the snapshot slot is checked.
With Incremental Snapshots, the full snapshot interval is going to be
_much_ higher, which would make this function wait for a looooong time.
So, if there's an incremental snapshot slot when checking, use that
slot, otherwise fall back to the full snapshot slot.
#### Problem
There's no way to get incremental snapshot information from RPC.
#### Summary of Changes
- Add new RPC method, `getHighestSnapshotSlot` that returns a `SnapshotSlotInfo`, which contains both the highest full snapshot slot, and the highest incremental snapshot slot _based on_ the full snapshot.
- Deprecate old RPC method, `getSnapshotSlot`
- Update API docs
Fixes#19579
This is the 2nd installment for the AccountsDb replication.
Summary of Changes
The basic google protocol buffer protocol for replicating updated slots and accounts. tonic/tokio is used for transporting the messages.
The basic framework of the client and server for replicating slots and accounts -- the persisting of accounts in the replica-side will be done at the next PR -- right now -- the accounts are streamed to the replica-node and dumped. Replication for information about Bank is also not done in this PR -- to be addressed in the next PR to limit the change size.
Functionality used by both the client and server side are encapsulated in the replica-lib crate.
There is no impact to the existing validator by default.
Tests:
Observe the confirmed slots replicated to the replica-node.
Observe the accounts for the confirmed slot are received at the replica-node side.
