* MADS: Refactor MADS safety with improved state management (pull request commaai#46)

Refactor MADS safety with improved state management

This commit introduces a major refactoring of the MADS safety module, improving state management and control flow. Key changes include:

Core Changes:
- Introduced a MADSState struct to centralize state management
- Removed global state variables in favor of structured state
- Implemented button transition handling with explicit state tracking (PRESSED/RELEASED/NO_CHANGE)
- Added state flags for button availability detection
- Simplified lateral control permission logic

Button Handling:
- Separated main button and LKAS button state tracking
- Added independent engagement states for each button
- Improved button press detection across multiple platforms
- Added support for main and LKAS buttons on Hyundai platforms
- Modified ACC main state handling

Testing:
- Added comprehensive test coverage for MADS state transitions
- Added new MADS-specific test base class for consistent testing across platforms
- Added mutation testing for state management
- Extended timeout for mutation tests from 5 to 8 minutes
- Added extensive button press validation tests
- Enhanced debugging output in replay drive tests

The refactored code provides a more organized implementation of MADS safety features while maintaining compatibility with existing safety checks.

* adding note

* adding ford (WIP)

* adding honda (WIP)

* adding toyota (WIP)

* adding chrysler (WIP)

* Standardize Button State Handling Across Platforms

Refactor button state handling by replacing integer constants with an enumerated `ButtonState` type and updating logic to improve readability and maintainability. This change affects button press detection in Ford, Honda, Hyundai, and Toyota safety modules and aligns them with a unified MADS button state approach. Enums provide a clearer understanding of button states and transitions, facilitating easier maintenance and future enhancements.

* Disable LKAS button press logic in Honda and Toyota safety.

The code for processing LKAS button presses has been commented out in both Honda and Toyota safety implementations. This change aims to investigate or temporarily halt the button press effects without removing the logic altogether. It will be important to test for any impacts this may have on vehicle control functionality.

* Remove commented out code in toyota_rx_hook function

This commit cleans up the toyota_rx_hook function by removing unnecessary commented-out code that checks for LKAS button presses on bus 2. This helps improve code readability and maintainability without altering the existing functionality.

* GM, mazda, nissan, subaru (global & preglobal)

* Honda LKAS

* go through all buttons

* try nissan

* more nissan

* nissan tests passed!

* subaru lkas test (not sure why it's not passing 2 and 3 values)

* Improved code organization in safety_subaru.h and test_subaru.py

This commit includes a minor restructuring in safety_subaru.h and test_subaru.py for better readability and flow. The condition check in safety_subaru.h for lkas_hud now has explicit parentheses. With regard to test_subaru.py, an unnecessary import was removed, and the sequence of steps in the test was reordered - now enabling mads and cleaning up mads_states happens before each subtest.

* Refactor tests to use _speed_msg instead of _user_brake_msg.

Updated the MADS safety tests to utilize the _speed_msg(0) function call in place of _user_brake_msg(False).

* Reworking the tests a little for clarity

* disabling lkas again on toyota temporarily

* fix mads condition to engage

* hyundai and honda good with new tests

* Redoing more tests

* update for safety tick ensuring mads control is exited while lagging

* Refactor safety replay script for better debugging and update Honda safety code

The commit performs a comprehensive revision of the safety replay script, specifically focusing on introducing debug variables and enhancing the logging capabilities for improved debugging. Furthermore, changes were made to the Honda safety code. The test helpers within libpanda were also expanded for inclusion of additional test conditions.

* Introduce 'ACC_MAIN_OFF' as a new disengagement reason in Sunnypilot's 'safety_mads.h'

The Sunnypilot's 'safety_mads.h' file has been updated to include 'ACC_MAIN_OFF' as a new cause for disconnection in the 'DisengageReason' enumeration. If an 'acc_main_off' signal is received, the 'mads_exit_controls' function halts all requests for lateral control engagement. Additionally, the status of 'controls_requested_lat' now mirrors 'controls_allowed_lat' after a button press.

* simpler logic cleaner

* reorder code for readability

* tmp

* Refactor state transitions and add event handlers

Renamed StateTransition to EdgeTransition for clarity and updated related logic. Introduced event handlers for button presses and ACC state changes, reducing duplicated control flow code. Improved encapsulation and maintainability by restructuring state update functions.

* reorder

* Refactor MADS state handling logic

Removed redundant event handler functions and unnecessary timestamp fields to streamline the code. Simplified button and binary state updates by integrating logic directly into transition checks. Commented out unused fields

* adding some more tests

* split init

* format

* update naming

* Refine lateral control request logic in safety_mads.h

The logic for setting the `controls_requested_lat` variable in safety_mads.h has been refined. Previously, it switched state based on the current value of `controls_allowed_lat`. Now, it also takes into account the current state of `acc_main`, ensuring a more nuanced control request mechanism that accounts for different operational scenarios.

* Fix button state handling in mads_exit_controls logic.

Refactor button state transitions to better handle lateral control requests when ACC is active. Ensure controls are correctly disengaged under specific conditions, by setting `controls_requested_lat` more reliably during state transitions. This change improves safety by preventing inadvertent disengagement when ACC is not active.

* Add test for LKAS button press with ACC main on

This commit introduces a new test to ensure that controls remain enabled when the LKAS/LFA button is pressed while ACC main is on. It checks that LKAS button operations don't interfere with control permissions in this specific configuration, improving test coverage and preventing potential safety issues.

* Add mismatch detection and change mads_acc_main to bool

Enhanced mismatch detection logic by tracking cases where 'controls_allowed' is true while 'controls_allowed_lat' is false, updating the script to print relevant debug information. Additionally, changed the data type of 'mads_acc_main' and 'mads_acc_main_prev' from int to bool for improved type accuracy and consistency.

* update controls_allowed_lat_pkt on health pkt to actually follow is_lat_active() which has the final word on whether we can allow lat or not.

* fix test with new controls allowed with system_mads off

* fix replay drive

* Change 'DISABLE_DISENGAGE_LATERAL_ON_BRAKE' to 'DISENGAGE_LATERAL_ON_BRAKE'

The commit modifies the usage of the 'DISABLE_DISENGAGE_LATERAL_ON_BRAKE' variable globally and replaces it with 'DISENGAGE_LATERAL_ON_BRAKE'. This change promotes correct and clear semantics, since the variable now indicates a state rather than the negation of a state.

* Refactor MADS state management to simplify pointer usage.

This change replaces many pointer-based state variables with direct ones, improving code readability and reducing complexity. It also standardizes the use of `const` for parameters and updates function implementations accordingly. These improvements enhance maintainability and reduce potential for pointer-related errors.

* Simplify braking logic in m_mads_check_braking function

Removed redundant conditions to streamline braking logic. This change maintains functionality while improving code readability and maintainability. Only necessary checks are now performed to determine disengagement.

* Prevent lateral control engagement during braking

Added a condition to disable lateral control engagement when braking with disengage-on-brake enabled. This change is marked as a demonstration and is not final for merging. Moved the disengage_reason to be set only when an actual disengagement occurred.

* Refactor MADS state handling and fix type consistency

Remove redundant `get_mads_state` inline definition and migrate it to a static function. Fix return type syntax in `get_mads_pending_disengage_reason`. Minor formatting adjustments improve readability and code clarity.

Refactor disengagement logic with enhanced reason tracking

Added distinction between active and pending disengagement reasons to improve system state tracking. Updated related enums, structs, and logic to ensure proper handling during control transitions. Added new safety tests to verify behavior under braking and ACC conditions.

Refactoring lateral control permissions and brake checks in MADS

This revision refactors the MADS safety code. The aim is to simplify and improve readability. Operations and checks for brake states and lateral control permissions have been consolidated into fewer methods. In addition, unused 'previous_disengage' state tracking has been removed from MADSState structure to avoid unnecessary state tracking. Moreover, the 'can_allow_controls_lat' function has been removed entirely and its functionality has been incorporated into other functions, reducing the function count and complexity of the code. The braking status is now tracked with BinaryStateTracking for consistency. These changes maintain the system's functionality while optimizing the code and improving maintainability.
