d282b0bf85 Report server domain to other servers:
This commit introduces a new configuration option that server
operators can set. The value is communicated to other servers
and is also reported via the `server_info` API.

The value is meant to allow third-party applications or tools
to group servers together. For example, a tool that visualizes
the network's topology can group servers together.

Similar to the "Domain" field in validator manifests, an operator
can claim any domain. Prior to relying on the value returned, the
domain should be verified by retrieving the xrp-ledger.toml file
from the domain and looking for the server's public key in the
`nodes` array.

51bd4626b1 Implement version upgrade warning:
If the 'HardenedValidations' amendment is enabled, this commit will
track the version of the software that validators embed in their
validations.

If a server notices that at least 60% of the validators on its UNL
are running a newer version than it is running, it will periodically
print an informational message, reminding the operator to check for
update.

Slice should, eventually, be replaced by std::string_view<std::uint8_t>
so begin adding some helpful functions to align its interface.

268e28a278 Tune relaying of untrusted proposals & validations:
In deciding whether to relay a proposal or validation, a server would
consider whether it was issued by a validator on that server's UNL.

While both trusted proposals and validations were always relayed,
the code prioritized relaying of untrusted proposals over untrusted
validations. While not technically incorrect, validations are
generally more "valuable" because they are required during the
consensus process, whereas proposals are not, strictly, required.

The commit introduces two new configuration options, allowing server
operators to fine-tune the relaying behavior:

The `[relay_proposals]` option controls the relaying behavior for
proposals received by this server. It has two settings: "trusted"
and "all" and the default is "trusted".

The `[relay_validations]` options controls the relaying behavior for
validations received by this server. It has two settings: "trusted"
and "all" and the default is "all".

This change does not require an amendment as it does not affect
transaction processing.

62a3f33d72 Remove the built-in "sustain" watchdog:
The built-in watchdog is simplistic and can, sometimes, cause problems
especially on systems that have the ability to automatically start and
monitor processes.

This commit removes the sustain system entirely, changes the handling
of the SIGTERM signal to properly terminate the process and improves
the error message reported to the user when the command line used to
start `rippled` is incorrect and malformed.

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.

284ed38471 Reduce calls to std::random_device:
Existing per-thread PRNGs are individually initialized using calls
to std::random_device.

If merged, this commit will use a single PRNG, initialized from
std::random_device on startup, to seed the thread-specific PRNGs.

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.

758a3792eb Add protocol message compression support:
* Peers negotiate compression via HTTP Header "X-Offer-Compression: lz4"
* Messages greater than 70 bytes and protocol type messages MANIFESTS,
  ENDPOINTS, TRANSACTION, GET_LEDGER, LEDGER_DATA, GET_OBJECT,
  and VALIDATORLIST are compressed
* If the compressed message is larger than the uncompressed message
  then the uncompressed message is sent
* Compression flag and the compression algorithm type are included
  in the message header
* Only LZ4 block compression is currently supported

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.

63503ee8f0 Improve platform detection and reduce includes:
The existing platform detection code was derived from the old Beast
library, which was, itself, derived from JUCE.

This commit removes that code and replaces it with the Boost.Predef
library which defines a consistent set of compiler, architecture,
operating system, library, and other version numbers.

For more on Boost.Predef, please see the Boost documentation. The
documentation for the current version as of this writing is at:

773dcd1d48 Modernize base_uint:
*  Add construction and assignment from a generic
   contiguous container.  Both compile-time and run time
   safety checks are made to ensure the safety of this
   conversion.

*  Remove base_uint::copyFrom.  The generic copy assignment
   operator now does this functionality with enhanced
   safety and better syntax.

*  Remove construction from and dedendence on Blob.
   The generic constructor and assignment now handle this
   functionality.

*  Fix client code to adhere to this new API.

*  Removed the use of fromVoid in PeerImp.cpp as it was
   an inappropriate use of this dangerous API.  The
   generic container constructors do it with enhanced
   safety and better syntax.

*  Rename data member pn to data_ and make it private.

*  Remove constraint from hash_append

*  Remove array_type alias

64b55c0f88 Rename JsonFields.h to jss.h:
At this point all of the jss::* names are defined in the same
file.  That file has been named JsonFields.h.  That file name
has little to do with either JsonStaticStrings (which is what
jss is short for) or with jss.  The file is renamed to jss.h
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
being parsed, it performed manual parsing of the hostname and port.

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.

156e8dae83 Replace WaitableEvent with portable std primitives:
The WaitableEvent class was a leftover from the pre-Boost
version of Beast and used Windows- and pthread-specific
APIs.

This refactor replaces that functionality by using only
interfaces provided by the C++ standard, making the code
more portable.

Closes #2402.

1ac9694dbc Simplify strHex:
Problem:
- There are several specific overloads with some custom code that can be
  easily replaced using Boost.Hex.

Solution:
- Introduce `strHex(itr, itr)` to return a string given a begin and end
  iterator.
- Remove `strHex(itr, size)` in favor of the `strHex(T)` where T is
  something that has a `begin()` member function. This allows us to
  remove the strHex overloads for `std::string`, Blob, and Slice.
