- Refactor `AppManifest`: add new fields and rename existing ones
- Parse and validate the manifest from an app that is being installed.
- Remove deprecated `scoped()` from `Lock`
- Create `Tactility/Paths.h`
- App loading at boot now properly parses the manifest files of external apps
- Properly lock both source and destination locations during app install
- Remove LVGL path variants from `AppPaths` and `ServicePaths`
- Removed `xPath` base classes for apps and services. There's now `AppPaths` and `ServicePaths`.
- Renamed app and service paths: "data" and "system" paths are now "user data" and "assets"
- Update ILI9341 driver to v2.0.1
- Lots of code cleanup for apps
- Refactor app "type" into "category" and added flags to the manifest (for show/hide statusbar and for hidden apps)
- Rename some ElfApp-related functionality and improved the way the static data was managed
- Rename "filebrowser" to "files"
- Added cstring functions to tt_init.cpp
- Minor fix in Boot app
- Updated external apps for SDK changes
## New features
- Implemented support for app packaging in firmware and `tactility.py`: load `.app` files instead of `.elf` files. Install apps remotely or via `FileBrowser`.
- Ensure headless mode works: all services that require LVGL can deal with the absence of a display
- Service `onStart()` is now allowed to fail (return `bool` result)
- Added and improved various file-related helper functions
## Improvements
- Completely revamped the SystemInfo app UI
- Improved Calculator UI of internal and external variant
- Fix Chat UI and removed the emoji buttons for now
- Fix for toolbar bottom padding issue in all apps
## Fixes
- Fix for allowing recursive locking for certain SPI SD cards
& more
- Create `Include/` folder for all main projects
- Fix some issues here and there (found while moving things)
- All includes are now in `Tactility/` subfolder and must be included with that prefix. This fixes issues with clashing POSIX headers (e.g. `<semaphore.h>` versus Tactility's `Semaphore.h`)
- Refactor the way apps work: Instead of a C interface, they are now C++ classes. The main reasoning is that attaching data to an app was cumbersome. Having different implementations for different kinds of apps was cumbersome too. (3 or 4 layers of manifest nesting for the TactilityC project)
- External apps are still written in C, but they get a createData/destroyData in their manifest, so:
- External apps now have their own manifest.
- All functions in the original AppManifest are removed and replaced by a single `createApp` function
- External apps now automatically register (each app individually!) when they run the first time. As a side-effect they become visible in the `AppList` app!
- Adapted all apps for the new interface.
- Adapted all internal logic for these changes (Gui, ViewPort, Loader, AppContext, AppInstance, etc.)
- Rewrote parts of Loader to use std::shared_ptr to make the code much safer.
- Added a refcount check for the `AppInstance` and `App` at the end of their lifecycle. Show warning if refcount is too high.
