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.
* clippy
Add new vote state version that replaces Lockout with LandedVote to allow vote latency to be tracked in a future change.
Includes a feature to be enabled which will when enabled cause the vote state to be written in the new form.

* Use flags to make the function calls more readable
* Remove the extra purge calls
* replace select_type with filter_by_type
* Add test

* use match and call do_purge once
* Let bank_snapshots_dir be TempDir
* remove account_paths in the test
* replace bank with _bank

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.

* Add --{replaying,banking}-backend flags (noop atm)
* Greatly simplify enums with strum
* Update programs/sbf/Cargo.lock...
* Rely on Display, removing Debug
* constify cli_names()
* Don't allow omitting bankend value
* Rename to --block-{verification,production}-method
* Use more specific name
* Actually support missing value....
* Remove strictly-unnecessary flags
* Use lazy_static! instead of abusing DefaultArgs...
`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.
* Clean up orphaned account snapshot hardlink dirs
* fix compilation issues
* debugged, now working. seeing the orphaned directories deleted

* 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.
