* 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.

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.

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.
* 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.
* add test
* pr comments

Additionally refactor subtrees to store children as a hashset
* Add a more complicated forks test
* chose -> choose
* remove is_dumped flag and reuse latest_invalid_ancestor instead
* Update cost model to use requested_cu instead of estimated cu #27608
* remove CostUpdate and CostModel from replay/tvu
* revive cost update service to send cost tracker stats
* CostModel is now static
* remove unused package

We have transactions counted in replay-slot-end-to-end-stats, but that
metric is broken down to report things per thread.
So, report total_transactions for the entire slot (all threads) in
replay-slot-stats.
* Check overflow on vote tx compaction boundary
Check for overflow during the conversion between VoteStateUpdate and
CompactVoteStateUpdate.
* Try removing clippy supress
Tenets:
1. Limit thread names to 15 characters
2. Prefix all Solana-controlled threads with "sol"
3. Use Camel case. It's more character dense than Snake or Kebab case
* Keypair: implement clone()
This was not implemented upstream in ed25519-dalek to force everyone to
think twice before creating another copy of a potentially sensitive
private key in memory.
See https://github.com/dalek-cryptography/ed25519-dalek/issues/76
However, there are now 9 instances of
Keypair::from_bytes(&keypair.to_bytes())
in the solana codebase and it would be preferable to have a function.
In particular since this also comes up when writing programs and can
cause users to either start messing with lifetimes or discover the
from_bytes() workaround themselves.
This patch opts to not implement the Clone trait. This avoids automatic
use in order to preserve some of the original "let developers think
twice about this" intention.
