Currently FDB TLS is allowing exactly one root CA to be added,
which makes servers unable to talk to each other if there are more than one.
Work around this problem by letting client and server share CA
* Add JsonWebKeySet parser/stringifier
* Update header directory
* Make JWKS parser correctness clean for OpenSSL 1.x
Add RSA keygen support
* Make JWKS parser correctness clean for OpenSSL 3.x
+extend unique_ptr for scoped destruction of OpenSSL objects
* Use PKey::{sign|verify}() in TokenSign
* Apply AutoCPointer to MkCert
* Apply Clang format
* JWKS::toStringRef() returns StringRef > Optional<StringRef>
* Fix Mac/Windows build error
* Fix incorrect fix of Mac build
* Fix filename in license comment for AutoCPointer.h
* Refactor complex C macros into function templates
* 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
