692070dbf1 Add semi-automatic rounding of STNumbers based on Asset types
- Create a new SField metadata enum, sMD_NeedsAsset, which indicates
  the field should be associated with an Asset so it can be rounded.
- Add a new STTakesAsset intermediate class to handle the Asset
  association to a derived ST class. Currently only used in STNumber,
  but could be used by other types in the future.
- Add "associateAsset" which takes an SLE and an Asset, finds the
  sMD_NeedsAsset fields, and associates the Asset to them. In the case
  of STNumber, that both stores the Asset, and rounds the value
  immediately.
- Transactors only need to add a call to associateAsset _after_ all of
  the STNumbers have been set. Unfortunately, the inner workings of
  STObject do not do the association correctly with uninitialized
  fields.
- When serializing an STNumber that has an Asset, round it before
  serializing.
- Add an override of roundToAsset, which rounds a Number value in place
  to an Asset, but without any additional scale.
- Update and fix a bunch of Loan-related tests to accommodate the
  expanded Number class.
- (Not all tests are fixed yet.)

af43572ee5 Review feedback from @shawnxie999: even more rounding
- Round the initial total value computation upward, unless there is
  0-interest.
- Rename getVaultScale to getAssetsTotalScale, and convert one incorrect
  computation to use it.
- Use adjustImpreciseNumber for LossUnrealized.
- Add some logging to computeLoanProperties.

813bc4d949 refactor: Replaces secp256k1 source by Conan package (#6089)
This change substitutes the secp256k1 source code copy by the Conan recipe added in XRPLF/conan-center-index#24, which updates the version of the library to 0.7.0.

947ad002e0 Review feedback from @Tapanito: overpayment value change
- In overpayment results, the management fee was being calculated twice:
  once as part of the value change, and as part of the fees paid.
  Exclude it from the value change.

43a6f10050 MPTTester::operator() parameter should be std::int64_t
- Originally defined as uint64_t, but the testIssuerLoan() test called
  it with a negative number, causing an overflow to a very large number
  that in some circumstances could be silently cast back to an int64_t,
  but might not be. I believe this is UB, and we don't want to rely on
  that.

ad190a8d6f Review feedback from @dangell7: early return & coverage
- Exclude LogicError lines in ApplyView.cpp (specifically directory
  operations) from code coverage.
- Replace the ability to set the next page on a new directory page with
  an assert, because nothing uses it right now.
- Early return with success for batch inner transactions in preflight2.

6c67f1f525 Implement Lending Protocol (unsupported) (#5270)
- Spec: XLS-66
- Introduces amendment "LendingProtocol", but leaves it UNSUPPORTED to
  allow for standalone testing, future development work, and potential
  bug fixes.
- AccountInfo RPC will indicate the type of pseudo-account when
  appropriate.
- Refactors and improves several existing classes and functional areas,
  including Number, STAmount, STObject, json_value, Asset, directory
  handling, View helper functions, and unit test helpers.

  (IOUAmount, STAmount).

Ed Hennis
a87460b89f Restore the original Number interface
- ctors and accessors return `rep`. Very few things expose
  `internalrep`.
- An exception is "unchecked" and the new "normalized", which explicitly
  take an internalrep. But with those special control flags, it's easier
  to distinguish and control when they are used.
- The goal is to get as much of the non-number code back to the previous
  state as possible.

77e3bbdc89 Move the ValidPseudoAccounts class back to its original location
- The class didn't actually change much, if at all, but somehow got
  relocated.
- This should make the review easier, and reduce the footprint of the
  PR.

- Created a common doWithdraw function for VaultWithdraw and
  LoanBrokerCoverWithdraw. Added verifyDepositPreauth to it, so that
  both transactions will get the check.
- Add a missing null check to LoanBrokerSet, and add log messages to the
  existing checks.
