Working towards LegacyContactInfo => ContactInfo migration, the commit
hides some implementation details of LegacyContactInfo and expands API
parity with the new ContactInfo.
* Fix bug where ReplayStage holds an Arc<Bank> for process lifetime
When ReplayStage::new() kicks off, it needs to do some setup with the
working bank prior to entering the main processing loop. This setup is
done before entering the main processing loop; however, a bug made it
such that an Arc<Bank> remained in scope after the processing loop had
been entered. The processing loop is only exited when the process exits,
so this means that Bank was being held for the lifetime of the process.
This is a waste of resources and prevents background cleanup.

Measure total time spent inside `confirm_slot_entries()`. Useful metric
in addition to `replay_elapsed` and
`poh_verify_elapsed`/`transaction_verify_elapsed`, as it shows how PoH
and transaction verification interact with the replay process.
Extracted time metrics related to transaction execution into a separate
structure. This allows me to call `process_entries_with_callback()`
without locking the whole instance of `ConfirmationTiming`, passing just
the `BatchExecutionTiming` part.
I want to add a new metric that starts at the beginning of the
`confirm_slot_entries()` call and ends until the very end. In order to
use a `scopeguard::defer`, I need to be able to have an excursive
reference to it for the whole body of `confirm_slot_entries()`.
Plus a few minor renamings to clarify which verifications and results
variables actually store. And corrected a few messages, that
incorrectly stated PoH verification, while they were actually issued
for transaction verification failures.

`poh_verify` actually disables transaction signature, tick count and
built in program argument verifications as well. It is somewhat
confusing to call it `poh_verify`.
Shreds arriving at tvu/tvu_forward/repair sockets are each processed in
a separate thread, and since each thread has its own deduper, the
duplicates across these sockets are not filtered out.
Using a common deduper across these threads will require an RwLock
wrapper and may introduce lock contention.
The commit instead moves the shred-deduper to shred-sigverify-stage
where all these shreds arrive through the same channel.
If turbine_disabled is true, the commit discards turbine packets
earlier in the pipeline so that they won't interfere with the deduper
and the packets can get through once turbine is enabled again.
This is a prerequisite of:
https://github.com/solana-labs/solana/pull/30786
so that local-cluster tests pass.
For duplicate block detection, for each (slot, shred-index, shred-type)
we need to allow 2 different shreds to be retransmitted.
The commit implements this using two bloom-filter dedupers:
* Shreds are deduplicated using the 1st deduper.
* If a shred is not a duplicate, then we check if:
(slot, shred-index, shred-type, k)
is not a duplicate for either k = 0 or k = 1 using the 2nd deduper,
and if so then the shred is retransmitted.
This allows to achieve larger capactiy compared to current LRU-cache.
generalizes Deduper to work with any hashable type
Current Deduper is hard-coded only for Packet type. In order to use
Deduper in retransmit-stage, we need to dedup types other than Packet.
The commit generalizes Deduper to any hashable type.

removes the false_positive_rate field from the Deduper
Deduper.false_positive_rate field is misleading because it is not
enforced until maybe_reset is called. But then maybe_reset can be
invoked with an explicit argument.

* minor comment cleanup
Current Deduper implementation uses many bits per entry:
https://github.com/solana-labs/solana/blob/65cd55261/perf/src/deduper.rs#L70-L73
and may be saturated quickly. It also lacks api to specify desired false
positive rate.
The commit instead uses an atomic bloom filter with K hash functions.
The false positive rate is obtained by tracking popcount of bits.
* Add RewardsMessage enum

* Nit: fix test
* Add helper function to create BlockstoreOptions from ValidatorConfig
* Make backup_and_clear_blockstore() honor ValidatorConfig options
backup_and_clear_blockstore() opens a Blockstore session; however, it
is currently using Blockstore::open(). This Blockstore method uses
BlockstoreOption::default() under the hood. As a result, any validator
args that adjust Blockstore settings are not considered in
backup_and_clear_blockstore().
This is especially problematic if the non-default value of
--rocksdb-shred-compaction is being used. In this case,
backup_and_clear_blockstore() was opening the wrong directory and
incorrectly finding an empty ledger.
This change plumbs any blockstore configuration to
backup_and_clear_blockstore().

Snapshot construction and interaction code was a bit more manual than necessary, even causing a bug to slip past a review. Separated snapshot construction from the diffing of two snapshots.
This should make the logic clearer.
A recent change to this service to store the number of non-vote
transactions introduced a bug in the computation of the number of
transactions during the time interval. This resulted in bogus values
being stored in Blockstore and eventually getting served through RPC for
the TPS chart on explorer.
Dynamic dispatch forces heap allocation and adds extra overhead.
Dynamic casting as in the ones below, lacks compile-time type safety:
https://github.com/solana-labs/solana/blob/eeb622c4e/quic-client/src/lib.rs#L172-L175https://github.com/solana-labs/solana/blob/eeb622c4e/udp-client/src/lib.rs#L52-L55
The commit removes all instances of Any, Box<dyn ...>, and Arc<dyn ...>,
and instead uses generic and associated types.
There are only two protocols QUIC and UDP; and the code which has to
work with both protocols can use a trivial thin enum wrapper.
With respect to connection-cache specifically:
* connection-cache/ConnectionCache is a single protocol cache which
allows to use either QUIC or UDP without any build dependency on the
other protocol.
* client/ConnectionCache is an enum wrapper around both protocols and
can be used in the code which has to work with both QUIC and UDP.

tpu-client/tpu_connection_cache is refactored out the module and moved to connection-cache/connection_cache and the logic in client/connection_cache is consolidated to connection-cache/connection_cache as well. client/connection_cache only has a thin wrapper which forward calls to connection-cache/connection_cache and deal with constructions of quic/udp connection cache for clients using them both.2.
The TpuConnection is refactored to ClientConnection to make it generic and functions renamed to be proper for other workflows. eg. tpu_addr -> server_addr, send_transaction --> send_data and etc...
The enum dispatch is removed so that we can make the bulk of code of quic and udp agnostic of each other. The client is possible to load quic or udp only into its runtime.
The generic type parameter in the tpu-client/tpu_connection_cache is removed in order to create both quic and udp connection cache and use the object to send transactions with multiple branching when sending data. The generic type parameters and associated types are dropped in other types in order to make the trait "object safe" for this purpose.
I have annotated the code explaining the reasoning and the refactoring source -> destination.
There is no functional changes
bench-tps has been performed for rpc-client, thin-client and tpu-client. And it is found the performance number largely match the ones before the refactoring.

find_packet_sender_stake_stage::FindPacketSenderStakeReceiver is quite
verbose to include in function arguments, and type name is descriptive
enough that it doesn't need to be qualified with the crate name in every
instance.
Currently, the cleanup service counts the number of shreds in the
database by iterating the entire SlotMeta column and reading the number
of received shreds for each slot. This gives us a fairly accurate count
at the expense of performing a good amount of IO.
Instead of counting the individual slots, use the live_files()
rust-rocksdb entrypoint that we expose in Blockstore. This API allows us
to get the number of entries (shreds) in the data shred column family by
reading file metadata. This is much more efficient from IO perspective.
When broadcasting shreds, turbine excludes the slot leader from the
random shuffle. Doing so, shreds should never loopback to the leader.
If shreds reaching retransmit stage are from the node's own leader slots
they should not be retransmited to any nodes.

* Increase turbine propagation const
Value is used as a delay threshold for issuing shred repairs and analysis is showing we are overly aggressive in requesting repairs. Shreds show up via turbine before the repair completes the vast majority of the time
* Use Duration type for MAX_TURBINE_PROPAGATION
Store non-vote transaction counts that are now recorded by the banks
into the `blockstore`.
`SamplePerformanceService` now populates `PerfSampleV2` with counts from
the banks.
Problem
The plugins need to know when all transactions for a block have been all notified to serve getBlock request correctly. As block and transaction notifications are sent asynchronously to each other it will be difficult.
Summary of Changes
Include the executed transaction count in block notification which can be used to check if all transactions have been notified.
The commit adds an associated SignedData type to Shred trait so that
merkle and legacy shreds can return different types for signed_data
method.
This would allow legacy shreds to point to a section of the shred
payload, whereas merkle shreds would compute and return the merkle root.
Ultimately this would allow to remove the merkle root from the shreds
binary.
The commit allocates 2% of slots to running experiments with different
turbine fanouts based on the slot number.
The experiment is feature gated with an additional feature to disable
the experiment.
* Plumb dumps from replay_stage to repair
When dumping a slot from replay_stage as a result of duplicate or
ancestor hashes, properly update repair subtrees to keep weighting and
forks view accurate.

* pr comments
* Support bi-directional quic communication, use the same endpoint for the quic server and client
This is needed for supporting using quic for repair
