* 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are withdrawn.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.
* Rename ASSERT to XRPL_ASSERT
* Upgrade to Anthithesis SDK 0.4.4, and use new 0.4.4 features
* automatic cast to bool, like assert
* Add instrumentation workflow to verify build with instrumentation enabled
* Copy Antithesis SDK version 0.4.0 to directory external/
* Add build option `voidstar` to enable instrumentation with Antithesis SDK
* Define instrumentation macros ASSERT and UNREACHABLE in terms of regular C assert
* Replace asserts with named ASSERT or UNREACHABLE
* Add UNREACHABLE to LogicError
* Document instrumentation macros in CONTRIBUTING.md
* Add fixNFTokenPageLinks amendment:
It was discovered that under rare circumstances the links between
NFTokenPages could be removed. If this happens, then the
account_objects and account_nfts RPC commands under-report the
NFTokens owned by an account.
The fixNFTokenPageLinks amendment does the following to address
the problem:
- It fixes the underlying problem so no further broken links
should be created.
- It adds Invariants so, if such damage were introduced in the
future, an invariant would stop it.
- It adds a new FixLedgerState transaction that repairs
directories that were damaged in this fashion.
- It adds unit tests for all of it.
* Add feature / amendment "InvariantsV1_1"
* Adds invariant AccountRootsDeletedClean:
* Checks that a deleted account doesn't leave any directly
accessible artifacts behind.
* Always tests, but only changes the transaction result if
featureInvariantsV1_1 is enabled.
* Unit tests.
* Resolves#4638
* [FOLD] Review feedback from @gregtatcam:
* Fix unused variable warning
* Improve Invariant test const correctness
* [FOLD] Review feedback from @mvadari:
* Centralize the account keylet function list, and some optimization
* [FOLD] Some structured binding doesn't work in clang
* [FOLD] Review feedback 2 from @mvadari:
* Clean up and clarify some comments.
* [FOLD] Change InvariantsV1_1 to unsupported
* Will allow multiple PRs to be merged over time using the same amendment.
* fixup! [FOLD] Change InvariantsV1_1 to unsupported
* [FOLD] Update and clarify some comments. No code changes.
* Move CMake directory
* Rearrange sources
* Rewrite includes
* Recompute loops
* Fix merge issue and formatting

Apply inner object templates to all remaining (non-AMM)
inner objects.
Adds a unit test for applying the template to sfMajorities.
Other remaining inner objects showed no problems having
templates applied.
