* 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.
* `account_objects` returns an invalid field error if `type` is not supported.
This includes objects an account can't own, or which are unsupported by `account_objects`
* Includes:
* Amendments
* Directory Node
* Fee Settings
* Ledger Hashes
* Negative UNL
The names of the files should reflect the name of the Dir class.

Fix interactions between NFTokenOffers and trust lines.
Since the NFTokenAcceptOffer does not check the trust line that
the issuer receives as a transfer fee in the NFTokenAcceptOffer,
if the issuer deletes the trust line after NFTokenCreateOffer,
the trust line is created for the issuer by the
NFTokenAcceptOffer. That's fixed.
Resolves#4925.
Fixes issue #4937.
The fixReducedOffersV1 amendment fixed certain forms of offer
modification that could lead to blocked order books. Reduced
offers can block order books if the effective quality of the
reduced offer is worse than the quality of the original offer
(from the perspective of the taker). It turns out that, for
small values, the quality of the reduced offer can be
significantly affected by the rounding mode used during
scaling computations.
Issue #4937 identified an additional code path that modified
offers in a way that could lead to blocked order books. This
commit changes the rounding in that newly located code path so
the quality of the modified offer is never worse than the
quality of the offer as it was originally placed.
It is possible that additional ways of producing blocking
offers will come to light. Therefore there may be a future
need for a V3 amendment.
* Add trap_tx_hash command line option
This new option can be used only if replay is also enabled. It takes a transaction hash from the ledger loaded for replay, and will cause a specific line to be hit in Transactor.cpp, right before the selected transaction is applied.
Price Oracle data-series logic uses `unordered_map` to update the Oracle object.
This results in different servers disagreeing on the order of that hash table.
Consequently, the generated ledgers will have different hashes.
The fix uses `map` instead to guarantee the order of the token pairs
in the data-series.
