Fix race condition
...
Without this patch, it was possible for two transactions with the same
'from' address to drive its balance below zero. With the patch, we'll
hold a write lock from just before we verify sufficient funds until
after those funds are deducted from the account.

Expire all transactions after some amount of time

Reject old transactions so that we can calculate an upper bound
for memory usage, and therefore ensure the server won't slow
down over time to crash due to memory exhaustion.

Reject transactions with a `last_id` that isn't from this ledger
...
Before this patch, a client could put any value into `last_id` and
was primarily there to ensure the transaction had a globally unique
signature. With this patch, the server can use `last_id` as an
indicator of how long its been since the transaction was created.
The server may choose to reject sufficiently old transactions so
that it can forget about old signatures.

Make accountant thread-safe
...
Before this change, parallel transaction processing required locking
the full accountant. Since we only call one method,
process_verified_transaction, the global lock equates to doing no
parallelization at all. With this change, we only lock the data that's
being written to.
