This commit cleans up and modernizes the JobQueue but does not change
the queueing logic. It focuses on simplifying the code by eliminating
awkward code constructs, like "invalid jobs" and the need for default
constructors.
It leverages modern C++ to initialize tables and data structures at
compile time and replaces `std:map` instances with directly indexed
arrays.
Lastly, it restructures the load tracking infrastructure and reduces
the need for dynamic memory allocations by supporting move semantics
and value types.

- Fix unlikely edge case in setCurrentThreadName
setCurrentThreadName accepts a std::string_view parameter, which is
not guaranteed to include a null terminator, which it then forwards
to OS-specific APIs that expect null-terminated C strings.

Due to rounding, the LPTokenBalance of the last LP might not match the LP's trustline balance. This was fixed for `AMMWithdraw` in `fixAMMv1_1` by adjusting the LPTokenBalance to be the same as the trustline balance. Since `AMMClawback` is also performing a withdrawal, we need to adjust LPTokenBalance as well in `AMMClawback.`
This change includes:
1. Refactored `verifyAndAdjustLPTokenBalance` function in `AMMUtils`, which both`AMMWithdraw` and `AMMClawback` call to adjust LPTokenBalance.
2. Added the unit test `testLastHolderLPTokenBalance` to test the scenario.
3. Modify the existing unit tests for `fixAMMClawbackRounding`.
* Add AMM bid/create/deposit/swap/withdraw/vote invariants:
- Deposit, Withdrawal invariants: `sqrt(asset1Balance * asset2Balance) >= LPTokens`.
- Bid: `sqrt(asset1Balance * asset2Balance) > LPTokens` and the pool balances don't change.
- Create: `sqrt(asset1Balance * assetBalance2) == LPTokens`.
- Swap: `asset1BalanceAfter * asset2BalanceAfter >= asset1BalanceBefore * asset2BalanceBefore`
and `LPTokens` don't change.
- Vote: `LPTokens` and pool balances don't change.
- All AMM and swap transactions: amounts and tokens are greater than zero, except on withdrawal if all tokens
are withdrawn.
* Add AMM deposit and withdraw rounding to ensure AMM invariant:
- On deposit, tokens out are rounded downward and deposit amount is rounded upward.
- On withdrawal, tokens in are rounded upward and withdrawal amount is rounded downward.
* Add Order Book Offer invariant to verify consumed amounts. Consumed amounts are less than the offer.
* Fix Bid validation. `AuthAccount` can't have duplicate accounts or the submitter account.
Combine multiple related debug log data points into a single
message. Allows quick correlation of events that
previously were either not logged or, if logged, strewn
across multiple lines, making correlation difficult.
The Heartbeat Timer and consensus ledger accept processing
each have this capability.
Also guarantees that log entries will be written if the
node is a validator, regardless of log severity level.
Otherwise, the level of these messages is at INFO severity.
* Add logging for amendment voting decision process
* When counting "received validations" to determine quorum, count the number of validators actually voting, not the total number of possible votes.
The current comment in the example cfg file incorrectly mentions both "may" and "must". This change fixes this comment to clarify that the default port of hosts is 2459 and that specifying it is therefore optional. It further sets the default port to 2459 instead of the legacy 51235.
This change enhances the filtering in the ledger, ledger_data, and account_objects methods by also supporting filtering by the canonical name of the LedgerEntryType using case-insensitive matching.
