* Add JWT support to TokenSign
* Encapsulate OpenSSL public/private key type
Type-safe passing around of keys without having to DER/PEM-serialize
(OpenSSL doesn't have distinct types for public and private key)
* Apply Clang format
* Add verify benchmark for JWT and FlatBuffers token
* Unit test base64url::{encode, decode}
* Make all payload fields optional
Let user code validate non-signature fields
* Make all payload fields optional
Completely defer field check to user code
* Move rapidjson from fdbclient to contrib
* Make fdbrpc's rapidjson linkage private
Currently only sources include them.
* Modify rapidjson path in apiversioner.py
* Algorithm::Unknown > Algorithm::UNKNOWN
* Add contrib/debug_determinism
Add an instrumentation-based technique for debugging unseen mismatches. Also guard a few existing sources of nondeterminism that don't affect unseen with the DEBUG_DETERMINISM macro.
Also change the simulated run loop to not run as the only task inside the real run loop, since that was a source of nondeterminism.
Also fix nondeterminism from calling timer_int
* Add StorageMetadataType::currentTime
Basically a deterministic-in-simulation version of timer_int that we can
use instead of timer_int for StorageMetadataType::createdTime
