- Refactor Number internals away from int64 to uint64 & a sign flag
- ctors and accessors use `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.
- For now, skip the larger mantissas in AMM transactions and tests
- Remove trailing zeros from scientific notation Number strings
- Update tests. This has the happy side effect of making some of the string
representations _more_ consistent between the small and large
mantissa ranges.
- 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.

This change renames all occurrences of `namespace ripple` and `ripple::` to `namespace xrpl` and `xrpl::`, respectively, as well as the names of test suites. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
- 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.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
This change specifically removes all copyright notices referencing Ripple, XRPLF, and certain affiliated contributors upon mutual agreement, so the notice in the LICENSE.md file applies throughout. Copyright notices referencing external contributions remain as-is. Duplicate verbiage is also removed.
* Add and Scale to VaultCreate
* Add round-trip calculation to VaultDeposit VaultWithdraw and VaultClawback
* Implement Number::truncate() for VaultClawback
* Add rounding to DepositWithdraw
* Disallow zero shares withdraw or deposit with tecPRECISION_LOSS
* Return tecPATH_DRY on overflow when converting shares/assets
* Remove empty shares MPToken in clawback or withdraw (except for vault owner)
* Implicitly create shares MPToken for vault owner in VaultCreate
* Review feedback: defensive checks in shares/assets calculations

This change fixes the suite names all around the test files, to make them match to the folder name in which this test files are located. Also, the RCL test files are relocated to the consensus folder, because they are testing consensus functionality.
The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.
Adds two CMake functions:
* add_module(library subdirectory): Declares an OBJECT "library" (a CMake abstraction for a collection of object files) with sources from the given subdirectory of the given library, representing a module. Isolates the module's headers by creating a subdirectory in the build directory, e.g. .build/tmp123, that contains just a symlink, e.g. .build/tmp123/basics, to the module's header directory, e.g. include/xrpl/basics, in the source directory, and putting .build/tmp123 (but not include/xrpl) on the include path of the module sources. This prevents the module sources from including headers not explicitly linked to the module in CMake with target_link_libraries.
* target_link_modules(library scope modules...): Links the library target to each of the module targets, and removes their sources from its source list (so they are not compiled and linked twice).
Uses these functions to separate and explicitly link modules in libxrpl:
Level 01: beast
Level 02: basics
Level 03: json, crypto
Level 04: protocol
Level 05: resource, server
You can set a thread-local flag to direct Number how to round
non-exact results with the syntax:
Number::rounding_mode prev_mode = Number::setround(Number::towards_zero);
This flag will stay in effect for this thread only until another call
to setround. The previously set rounding mode is returned.
You can also retrieve the current rounding mode with:
Number::rounding_mode current_mode = Number::getround();
The available rounding modes are:
* to_nearest : Rounds to nearest representable value. On tie, rounds
to even.
* towards_zero : Rounds towards zero.
* downward : Rounds towards negative infinity.
* upward : Rounds towards positive infinity.
The default rounding mode is to_nearest.
* Conversions to Number are implicit
* Conversions away from Number are explicit and potentially lossy
* If lossy, round to nearest, and to even on tie
