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.

The specification for this change can be found at:

706ca874b0 Implement negative UNL functionality:
This change can help improve the liveness of the network during periods of network
instability, by allowing the network to track which validators are presently not online
and to disregard them for the purposes of quorum calculations.

5ff23f8f31 Warn operators about upcoming unknown amendments:
* When an unknown amendment reaches majority, log an error-level
  message, and return a `warnings` array on all successful
  admin-level RPC calls to `server_info` and `server_state` with
  a message describing the problem, and the expected deadline.
* In addition to the `amendment_blocked` flag returned by
  `server_info` and `server_state`, return a warning with a more
  verbose description when the server is amendment blocked.
* Check on every flag ledger to see if the amendment(s) lose majority.
  Logs again if they don't, resumes normal operations if they did.

The intention is to give operators earlier warning that their
instances are in danger of being amendment blocked, which will
hopefully motivate them to update ahead of time.

79e9085dd1 Augment "submit" command response:
If merged, this commit will report additional information in the
response to the submit command; this will make it easier for developers
to accurately track the status of transaction submission.

Fixes #2851

607328e1a0 Improve the 'network_id' configuration option:
The 'network_id' option allows an administrator to specify to which
network they intend a server to connect. Servers can leverage this
information to optimize routing and prune automatically discovered
cross-network connections.

This commit will, if merged:

- add support for the devnet keyword, which corresponds to network ID #2;
- report the network ID, if one is configured, in server_info

47501b7f99 Provide additional info with txnNotFound errors.
* The `tx` command now supports min_ledger and max_ledger fields.
* If the requested transaction isn't found and these fields are
  provided, the error response indicates whether or not every
  ledger in the the provided range was searched.

This fixes #2924

a3a9dc26b4 Introduce support for deletable accounts:
The XRP Ledger utilizes an account model. Unlike systems based on a UTXO
model, XRP Ledger accounts are first-class objects. This design choice
allows the XRP Ledger to offer rich functionality, including the ability
to own objects (offers, escrows, checks, signer lists) as well as other
advanced features, such as key rotation and configurable multi-signing
without needing to change a destination address.

The trade-off is that accounts must be stored on ledger. The XRP Ledger
applies reserve requirements, in XRP, to protect the shared global ledger
from growing excessively large as the result of spam or malicious usage.

Prior to this commit, accounts had been permanent objects; once created,
they could never be deleted.

This commit introduces a new amendment "DeletableAccounts" which, if
enabled, will allow account objects to be deleted by executing the new
"AccountDelete" transaction. Any funds remaining in the account will
be transferred to an account specified in the deletion transaction.

The amendment changes the mechanics of account creation; previously
a new account would have an initial sequence number of 1. Accounts
created after the amendment will have an initial sequence number that
is equal to the ledger in which the account was created.

Accounts can only be deleted if they are not associated with any
obligations (like RippleStates, Escrows, or PayChannels) and if the
current ledger sequence number exceeds the account's sequence number
by at least 256 so that, if recreated, the account can be protected
from transaction replay.

9196d9541a Include validator's master public key in validation stream:
The validation stream only reported the ephemeral signing key for validators
which use manifests. This made tracking unnecessarily difficult for clients
processing the data stream.

With this change, the validator's long-term master public key is also
included.

This commit fixes #3005

* Provide proposing validator's master key in the validation stream
  subscription JSON responses.

Implement code review changes.

87e9ee5ce9 Add support for reserved peer slots:
This commit allows server operators to reserve slots for specific
peers (identified by the peer's public node identity) and to make
changes to the reservations while the server is operating.

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.
