Jacqueline Deans 9c8799610f Variable Server - var_send_once and integration test (#1330) ... * Adds the send_once command and message type, which allows a user to request a variable to be sent immediately and only once (intended to replace the var_add, var_send, var_clear idiom that is commonly used for this purpose) * Minor refactoring of variable server internals to reduce repeated code * Adds SIM_test_varserv to integration test to test basic variable server functionality * Changes graphics client for SIM_billiards to use var_send_once as an example of intended use * Add documentation for var_send_once in docs and tutorial * Set exit_code_enabled in trick unit tests to be true by default * Patch for failing bookworm build		2022-08-18 10:47:07 -05:00
