- Specification: XRPLF/XRPL-Standards#239
- Amendment: `SingleAssetVault`
- Implements a vault feature used to store a fungible asset (XRP, IOU, or MPT, but not NFT) and to receive shares in the vault (an MPT) in exchange.
- A vault can be private or public.
- A private vault can use permissioned domains, subject to the `PermissionedDomains` amendment.
- Shares can be exchanged back into asset with `VaultWithdraw`.
- Permissions on the asset in the vault are transitively applied on shares in the vault.
- Issuer of the asset in the vault can clawback with `VaultClawback`.
- Extended `MPTokenIssuance` with `DomainID`, used by the permissioned domain on the vault shares.

This change implements the account permission delegation described in XLS-75d, see https://github.com/XRPLF/XRPL-Standards/pull/257.
* Introduces transaction-level and granular permissions that can be delegated to other accounts.
* Adds `DelegateSet` transaction to grant specified permissions to another account.
* Adds `ltDelegate` ledger object to maintain the permission list for delegating/delegated account pair.
* Adds an optional `Delegate` field in common fields, allowing a delegated account to send transactions on behalf of the delegating account within the granted permission scope. The `Account` field remains the delegating account; the `Delegate` field specifies the delegated account. The transaction is signed by the delegated account.
- Also get the branch name.
- Use rev-parse instead of describe to get a clean hash.
- Return the git hash and branch name in server_info for admin
connections.
- Include git hash and branch name on separate lines in --version.
- spec: XRPLF/XRPL-Standards#220
- amendment: "DeepFreeze"
- implemented deep freeze spec to allow token issuers to prevent currency holders from being able to acquire more of these tokens.
- in combination with normal freeze, deep freeze effectively prevents any balance trust line balance change of a currency holder (except direct issuer <-> holder payments).
- added 2 new invariant checks to verify that deep freeze cannot be enacted without normal freeze and transfer is not frozen.
- made some fixes to existing freeze handling.

The LEDGER_ENTRY macro now takes an additional parameter, which makes it easier to avoid missing including the new field in jss.h and to the list of account_objects/ledger_data filters.
* Add fixNFTokenPageLinks amendment:
It was discovered that under rare circumstances the links between
NFTokenPages could be removed. If this happens, then the
account_objects and account_nfts RPC commands under-report the
NFTokens owned by an account.
The fixNFTokenPageLinks amendment does the following to address
the problem:
- It fixes the underlying problem so no further broken links
should be created.
- It adds Invariants so, if such damage were introduced in the
future, an invariant would stop it.
- It adds a new FixLedgerState transaction that repairs
directories that were damaged in this fashion.
- It adds unit tests for all of it.
