* Restrict access to Bank's HardForks
Callers could previously obtain a a lock to read/write HardForks from
any Bank. This would allow any caller to modify, and creates the
opportunity for inconsistent handling of what is considered a valid hard
fork (ie too old).
This PR adds a function to Bank so consistent sanity checks can be
applied; the caller will already have a Bank as that is where they would
have obtained the HardForks from in the first place. Additionally,
change the getter to return a copy of HardForks (simple Vec).
* Allow hard fork at bank slot if bank is not yet frozen
The core/src/ directory is already pretty crowded, and moving these
items into the subdirectory more clearly identifies that they are tied
to banking_stage.
* Add TpuEntryNotifier to send EntryNotifications from Tpu
* Optionally run TpuEntryNotifier to send out EntrySummarys alongside BroadcastStage messages
* Track entry index in TpuEntryNotifier
* Allow for leader slots that switch forks
* Exit if broadcast send fails
`Arc` is already a reference internally, so it does not seem to be
beneficial to pass a reference to it. Just adds an extra layer of
indirection.
Functions that need to be able to increment `Arc` reference count need
to take `Arc<AtomicBool>`, but those that just want to read the
`AtomicBool` value can accept `&AtomicBool`, making them a bit more
generic.
This change focuses specifically on `Arc<AtomicBool>`. There are other
uses of `&Arc<T>` in the code base that could be converted in a similar
manner. But it would make the change even larger.
The callstack updated in this PR passed an &Arc<...> down only to have
the bottom level clone the reference. Thus, we are giving shared
ownership so the reference is a bit redundant and arguably obscures the
intention to clone further down the callstack.

Counters incur additional overhead in sending points to the MetricsAgent
over a crossbeam channel. Additionally, some of these counters would be
submitted by non-voting nodes which is just extra overhead and noise.
This change condenses several updates of a counter into a field of the
existing BankingStageStats metrics struct.
replay_stage-voted_empty_bank has been converted into a datapoint that
now includes slot number. replay_stage-replay_transactions has been
removed altogether as we can get similar information on a per-slot basis
from replay-slot-stats metric.

When ReplayStage repeatedly fails to compute the correct for a block
after purging and repairing, it panics on the assumption that something
is very wrong and will require human intervention.
If this is the case, there is typically something to be debugged, and
having the slot available locally is valuable. This change does the
retry check that will panic before purging the failure slot.
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.
