Add DepositPreauth ledger type and transaction (RIPD-1624):

Browse Source 
The lsfDepositAuth flag limits the AccountIDs that can deposit into
the account that has the flag set.  The original design only
allowed deposits to complete if the account with the flag set also
signed the transaction that caused the deposit.

The DepositPreauth ledger type allows an account with the
lsfDepositAuth flag set to preauthorize additional accounts.
This preauthorization allows them to sign deposits as well.  An
account can add DepositPreauth objects to the ledger (and remove
them as well) using the DepositPreauth transaction.
