      DRIVERS-3082:
      Summary of necessary driver changes

      • Upgrade libmongocrypt to 1.13.0.
      • Update libmongocrypt bindings to pass all listCollection results in the MONGOCRYPT_CTX_NEED_MONGO_COLLINFO(_WITH_DB) states. Call mongocrypt_setopt_enable_multiple_collinfo to indicate the new behavior is implemented.
      • Implement prose tests from 527e22d.

      libmongocrypt binding changes
      libmongocrypt's protocol previously assumed auto encrypting a command only required at most one schema. With $lookup there can be multiple schemas on an aggregate command. As a result, a small driver change is needed: feed all listCollections results to libmongocrypt in the MONGOCRYPT_CTX_NEED_MONGO_COLLINFO(_WITH_DB) states. The previous protocol only required returning the first. Call mongocrypt_setopt_enable_multiple_collinfo to indicate the new behavior is implemented (otherwise libmongocrypt returns an error if a command requires multiple schemas).

      The libmongocrypt documentation describes the updated protocol in integrating.md.

      See the small protocol change implemented in the C driver here.

      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?
      3. Which versions of the driver/connector does this apply to?
