1eac4d2c07 APIv2: remove tx_history and ledger_header (#4759)
Remove `tx_history` and `ledger_header` methods from API version 2.

Update `RPC::Handler` to allow for methods (or method implementations)
to be API version specific. This partially resolves #4727. We can now
store multiple handlers with the same name, as long as they belong to
different (non-overlapping) API versions. This necessarily impacts the
handler lookup algorithm and its complexity; however, there is no
performance loss on x86_64 architecture, and only minimal performance
loss on arm64 (around 10ns). This design change gives us extra
flexibility evolving the API in the future, including other parts of
#4727.

In API version 2, `tx_history` and `ledger_header` are no longer
recognised; if they are called, `rippled` will return error
`unknownCmd`

36cb5f90e2 Introduce replacement for getting and setting thread name: (#4312)
* In namespace ripple, introduces get_name function that takes a
  std:🧵:native_handle_type and returns a std::string.
* In namespace ripple, introduces get_name function that takes a
  std::thread or std::jthread and returns a std::string.
* In namespace ripple::this_thread, introduces get_name function
  that takes no parameters and returns the name of the current
  thread as a std::string.
* In namespace ripple::this_thread, introduces set_name function
  that takes a std::string_view and sets the name of the current
  thread.
* Intended to replace the beast utilities setCurrentThreadName
  and getCurrentThreadName.

c6fee28b92 refactor: change the return type of mulDiv to std::optional (#4243)
- Previously, mulDiv had `std::pair<bool, uint64_t>` as the output type.
  - This is an error-prone interface as it is easy to ignore when
    overflow occurs.
- Using a return type of `std::optional` should decrease the likelihood
  of ignoring overflow.
  - It also allows for the use of optional::value_or() as a way to
    explicitly recover from overflow.
- Include limits.h header file preprocessing directive in order to
  satisfy gcc's numeric_limits incomplete_type requirement.

Fix #3495

dffcdea12b fix: Expected to return a value: (#4401)
Fix a case where `ripple::Expected` returned a json array, not a value.

The problem was that `Expected` invoked the wrong constructor for the
expected type, which resulted in a constructor that took multiple
arguments being interpreted as an array.

A proposed fix was provided by @godexsoft, which involved a minor
adjustment to three constructors that replaces the use of curly braces
with parentheses. This makes `Expected` usable for
[Clio](https://github.com/XRPLF/clio).

A unit test is also included to ensure that the issue doesn't occur
again in the future.

84cde3ce0b Use <=> operator for base_uint, Issue, and Book: (#4411)
- Implement the `operator==` and the `operator<=>` (aka the spaceship
  operator) in `base_uint`, `Issue`, and `Book`. 
- C++20-compliant compilers automatically provide the remaining
  comparison operators (e.g. `operator<`, `operator<=`, ...).
- Remove the function compare() because it is no longer needed.
- Maintain the same semantics as the existing code.
- Add some unit tests to gain further confidence.
- Fix #2525.

3f33471220 Introduce rounding modes for Number:
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.

e4b17d1cf2 XRPFees: Fee setting and handling improvements (#4247)
* Introduces amendment `XRPFees`
* Convert fee voting and protocol messages to use XRPAmounts
* Includes Validations, Change transactions, the "Fees" ledger object,
  and subscription messages

* Improve handling of 0 drop reference fee with TxQ. For use with networks that do not want to require fees
* Note that fee escalation logic is still in place, which may cause the
  open ledger fee to rise if the network is busy. 0 drop transactions
  will still queue, and fee escalation can be effectively disabled by
  modifying the configuration on all nodes

* Change default network reserves to match Mainnet

* Name the new SFields *Drops (not *XRP)
* Reserve SField IDs for Hooks

* Clarify comments explaining the ttFEE transaction field validation

0839a202c9 Reduce console noise coming from unit tests:
A few unit tests have historically generated a lot of noise
to the console from log writes.  This noise was not useful
and made it harder to locate actual test failures.

By changing the log level of these tests from
- severities::kError to
- severities::kDisabled
it was possible to remove that noise coming from the logs.

f072469409 Simplify & modernize code:
- Simplify and consolidate code for parsing hex input.
- Replace beast::endian::order with boost::endian::order.
- Simplify CountedObject code.
- Remove pre-C++17 workarounds in favor of C++17 based solutions.
- Improve `base_uint` and simplify its hex-parsing interface by
  consolidating the `SexHex` and `SetHexExact` methods into one
  API: `parseHex` which forces callers to verify the result of
  the operation; as a result some public-facing API endpoints
  may now return errors when passed values that were previously
  accepted.
- Remove the simple fallback implementations of SHA2 and RIPEMD
  introduced to reduce our dependency on OpenSSL. The code is
  slow and rarely, if ever, exercised and we rely on OpenSSL
  functionality for Boost.ASIO as well.

dbee3f01b7 Clean up and modernize code:
This commit removes obsolete comments, dead or no longer useful
code, and workarounds for several issues that were present in older
compilers that we no longer support.

Specifically:

- It improves the transaction metadata handling class, simplifying
  its use and making it less error-prone.
- It reduces the footprint of the Serializer class by consolidating
  code and leveraging templates.
- It cleanups the ST* class hierarchy, removing dead code, improving
  and consolidating code to reduce complexity and code duplication.
- It shores up the handling of currency codes and the conversation
  between 160-bit currency codes and their string representation.
- It migrates beast::secure_erase to the ripple namespace and uses
  a call to OpenSSL_cleanse instead of the custom implementation.

f22fcb3b2a Rename canonicalize into two functions:
* canonicalize_replace_cache
* canonicalize_replace_client

Now it is clear at the call site that if there are
duplicate copies of the data between the cache and
the caller, which copy gets replaced.

Additionally data parameter is now const-correct.
If it is not going to be replaced (canonicalize_replace_cache),
then the shared_ptr to the client data is const.

2c71802e38 Propagate validator lists (VLs or UNLs) over the peer network:
* Whenever a node downloads a new VL, send it to all peers that
  haven't already sent or received it. It also saves it to the
  database_dir as a Json text file named "cache." plus the public key of
  the list signer. Any files that exist for public keys provided in
  [validator_list_keys] will be loaded and processed if any download
  from [validator_list_sites] fails or no [validator_list_sites] are
  configured.
* Whenever a node receives a broadcast VL message, it treats it as if
  it had downloaded it on it's own, broadcasting to other peers as
  described above.
* Because nodes normally download the VL once every 5 minutes, a single
  node downloading a VL with an updated sequence number could
  potentially propagate across a large part of a well-connected network
  before any other nodes attempt to download, decreasing the amount of
  time that different parts of the network are using different VLs.
* Send all of our current valid VLs to new peers on connection.
  This is probably the "noisiest" part of this change, but will give
  poorly connected or poorly networked nodes the best chance of syncing
  quickly. Nodes which have no http(s) access configured or available
  can get a VL with no extra effort.
* Requests on the peer port to the /vl/<pubkey> endpoint will return
  that VL in the same JSON format as is used to download now, IF the
  node trusts and has a valid instance of that VL.
* Upgrade protocol version to 2.1. VLs will only be sent to 2.1 and
  higher nodes.
* Resolves #2953

761bb5744e Make XRPAmount constructor explicit:
Remove the implicit conversion from int64 to XRPAmount. The motivation for this
was noticing that many calls to `to_string` with an integer parameter type were
calling the wrong `to_string` function. Since the calls were not prefixed with
`std::`, and there is no ADL to call `std::to_string`, this was converting the
int to an `XRPAmount` and calling `to_string(XRPAmount)`.

Since `to_string(XRPAmount)` did the same thing as `to_string(int)` this error
went undetected.

so the file name better reflects what the file contains.

All includes of that file are fixed.  A few include order
issues are tidied up along the way.

dc4d76f626 Prefer regex to manual parsing in parseURL:
Although `parseURL` used a regex to pull the authority out of the URL

This commit rolls the parsing of the username and password, if any,
directly into the regex. The hostname can be a name, an IPv4 or an
IPv6 address.

c1a02440dc Load validator list from file:
* Adds local file:// URL support to the [validator_list_sites] stanza.
  The file:// URL must not contain a hostname. Allows a rippled node
  operator to "sideload" a new list if their node is unable to reach
  a validator list's web site before an old list expires. Lists
  loaded from a file will be validated in the same way a downloaded
  list is validated.
* Generalize file/dir "guards" from Config test so they can be reused
  in other tests.
* Check for error when reading validators.txt. Saves some parsing and
  checking of an empty string, and will give a more meaningful error.
* Completes RIPD-1674.
