a06525649d Use libsecp256k1 instead of OpenSSL for key derivation:
While most of the code associated with secp256k1 operations had
been migrated to libsecp256k1, the deterministic key derivation
code was still using calls to OpenSSL.

If merged, this commit replaces the OpenSSL-based routines with
new libsecp256k1-based implementations. No functional change is
expected and the change should be transparent.

This commit also removes several support classes and utility
functions that wrapped or adapted various OpenSSL types that
are no longer needed.

A tip of the hat to the original author of this truly superb
library, Dr. Pieter Wuille, and to all other contributors.

b4699c3b46 Improve the Byzantine validator detector:
This commit expands the detection capabilities of the Byzantine
validation detector. Prior to this commit, only validators that
were on a server's UNL were monitored. Now, all the validations
that a server receives are passed through the detector.

27d978b891 Simplify SHAMapItem construction:
The existing class offered several constructors which were mostly
unnecessary. This commit eliminates all existing constructors and
introduces a single new one, taking a `Slice`.

The internal buffer is switched from `std::vector` to `Buffer` to
save a minimum of 8 bytes (plus the buffer slack that is inherent
in `std::vector`) per SHAMapItem instance.

f91b568069 Add support for deterministic database shards (#2688):
Add support to allow multiple indepedent nodes to produce a binary identical
shard for a given range of ledgers. The advantage is that servers can use
content-addressable storage, and can more efficiently retrieve shards by
downloading from multiple peers at once and then verifying the integrity of
a shard by cross-checking its checksum with the checksum other servers report.

a2e1a7a84d TicketSequence with non-zero Sequence is an error:
Before this change any non-zero Sequence field was handled as
a non-ticketed transaction, even if a TicketSequence was
present.  We learned that this could lead to user confusion.
So the rules are tightened up.

Now if any transaction contains both a non-zero Sequence
field and a TicketSequence field then that transaction
returns a temSEQ_AND_TICKET error code.

The (deprecated) "sign" and "submit" RPC commands are tuned
up so they auto-insert a Sequence field of zero if they see
a TicketSequence in the transaction.

No amendment is needed because this change is going into
the first release that supports the TicketBatch amendment.

70bacb349e Improve manifest relaying and domain reporting:
- The changes to manifest relaying introduced with commit f74b469e68
  will cause newly accepted manifests to be sent back to the peer from
  which they were received. This no longer happens: a newly accepted
  manifest is never sent back to the peer we received it from.
- When encountering a manifest without a domain set, the `manifest` and
  `validator_info` commands would include an empty string as the domain
  associated with the manifest. This no longer happens: if a domain is
  not present, the `domain` field will not be.

44fe0e1fc4 Add support for the 'TicketBatch' amendment:
Support for 'out-of-sequence' transaction execution was introduced
in commit 7724cca384.

The changes in that commit were gated under a feature but there was
no corresponding amendment introduced that would allow the network
to vote on this amendment.

This commit introduces 'TicketBatch' amendment as the amendment
that is associated with the tickets feature. If the amendment is
enabled, it will activate support for tickets.

This commit also removes several workarounds that are no longer
needed in unit tests.

* Also causes rippled to lock down if it has no valid UNLs, similar to
  being amendment blocked, except reversible.
* Resolves #3548
* Resolves #3470

6dd3d825c8 Adjust time resolution of genesis ledger:
Due to some quirky emergent behavior, the server can't really begin
synching until twice the default close time resolution of the genesis
ledger, which is 30 seconds, has passed. In effect, this causes a one
minute delay.

This commit adjusts the default close time resolution down to the
minimum allowed resoluion of 10 seconds, so the corresponding delay
is reduced by 67% down to 20 seconds. This should be enough time to
ensure the server has reasonable connectivity without unduly delaying
initial synch times.

28ed2b9e69 Persist API-configured voting settings:
Prior to this commit, the amendments that a server would vote in support
of or against could be configured both via the configuration file and
via the command line "feature" command. Changes made in the configuration
file would only be loaded once at server startup and changes made via the
command line take effect immediately but are not persisted across
restarts.

This commit deprecates management of amendments via the configuration
file and stores the relevant information in the `wallet.db` database
file.

1. On startup, the new code parses the configuration file.
2. If the `[veto_amendments]` or `[amendments]` sections are present,
   we check if the `FeatureVotes` table is present in `wallet.db`.
3. If it is not, we create the `FeatureVotes` table and transfer the
   settings from the config file.
4. Proceed normally but only reference the `FeatureVotes` table instead
   of the config file.
5. Warns if the voting table already exists in `wallet.db` and there
   exists voting sections in the config file. The config file is ignored
   in this case.

This change addresses & closes #3366

deea16e14f Correct handling of corner-cases involving custom iterators:
- Under some conditions, comparing `ReadViewFwdRange::iterators`
  for equality could derefence an empty `std::unique_ptr` which
  will result in a crash.
- Misuse of the `equal` API could result in a `std::bad_cast`
  exception being thrown from when iterating transactions or
  SLEs from the `OpenView`, `RawStateTable` and `Ledger` classes.

1bb294afbc Refactor and improve the SHAMap code:
This commit combines a number of cleanups, targeting both the
code structure and the code logic. Large changes include:

 - Using more strongly-typed classes for SHAMap nodes, instead of relying
   on runtime-time detection of class types. This change saves 16 bytes
   of memory per node.
 - Improving the interface of SHAMap::addGiveItem and SHAMap::addItem to
   avoid the need for passing two bool arguments.
 - Documenting the "copy-on-write" semantics that SHAMap uses to
   efficiently track changes in individual nodes.
 - Removing unused code and simplifying several APIs.
 - Improving function naming.

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.

ab77444fa3 Simplify SHAMapNodeID:
The existing SHAMapNodeID object has both a valid and an invalid state
and requirs callers to verify the state of an instance prior to using
it. A simple set of changes removes that restriction and ensures that
all instances are valid, making the code more robust.

This change also:

1. Introduces a new function to construct a SHAMapNodeID from a
   serialized blob; and
2. Reduces the amount of constructors the class exposes.

cba6b4a749 Improve handling of peers that aren't synced:
When evaluating the fitness and usefulness of an outbound peer, the code
would incorrectly calculate the amount of time that the peer spent in
a non-useful state.

This commit, if merged, corrects the calculation and makes the timeout
values configurable by server operators.

Two new options are introduced in the 'overlay' stanza of the config
file. The default values, in seconds, are:

[overlay]
max_unknown_time = 600
max_diverged_time = 300

bec6c626d8 Add finer-grained control for incoming & outgoing peer limits:
This commit replaces the `peers_max` configuration element which had
a predetermined split between incoming and outgoing connections with
two new configuration options, `peers_in_max` and `peers_out_max`,
which server operators can use to explicitly control the number of
incoming and outgoing peer slots.

17abca1caa Use macros to instantiate most SField instances:
There have been cases in the past where SFields have been defined
in such a way that they did not follow our conventions.  In
particular, the string representation of an SField should match
the in-code name of the SField.

This change leverages the preprocessor to encourage SFields to
be properly constructed.

The suffixes of SField types are changed to be the same as
the suffixes of corresponding SerializedTypeIDs.  This allows
The preprocessor to match types using simple name pasting.

Since the string representation of the SField is part of our
stable API, the name of sfPayChannel was changed to sfChannel.
This change allows sfChannel to follow our conventions while
making no changes to our external API.

795de3a75a Load transaction metadata from SQLite:

and its metadata directly from SQLite.

9b9f34f881 Optimize relaying of validation and proposal messages:
With few exceptions, servers will typically receive multiple copies
of any given message from its directly connected peers. For servers
with several peers this can impact the processing latency and force
it to do redundant work. Proposal and validation messages are often
relayed with extremely high redundancy.

This commit, if merged, introduces experimental code that attempts
to optimize the relaying of proposals and validations by allowing
servers to instruct their peers to "squelch" delivery of selected
proposals and validations. Servers making squelching decisions by
a process that evaluates the fitness and performance of a given
server and randomly selecting a subset of the best candidates.

The experimental code is presently disabled and must be explicitly
enabled by server operators that wish to test it.

7724cca384 Implement enhanced Ticket support:
Tickets are a mechanism to allow for the "out-of-order" execution of
transactions on the XRP Ledger.

This commit, if merged, reworks the existing support for tickets and
introduces support for 'ticket batching', completing the feature set
needed for tickets.

The code is gated under the newly-introduced `TicketBatch` amendment
and the `Tickets` amendment, which is not presently active on the
network, is being removed.

dbd5f0073e Revert support for deterministic shards:
Commit 4dc08f820258ac6c62071c7070c175e48352f8b3 introduced support for
deterministic shards, which makes the sharding functionality provided
by rippled more useful.

After merging, several opportunities for further improvements to the
deterministic sharding implementation were identified and a significant
increase int memory usage during shard finalization was detected.

Because of these issues, the commit is being reverted and the feature is
being rolled back. It will be reintroduced in a future release.
