In order to minimize the use of exceptions during normal operations, each request handler is now able to return either a proper JSON value, or an instance of api_error, which indicates that something went wrong, but without having to throw, catch and rethrow C++ exceptions. This is especially important for conditional updates, since it's expected to be common to return ConditionalCheckFailedException.
