* fbt, faploader: minimal app module implementation * faploader, libs: moved API hashtable core to flipper_application * example: compound api * lib: flipper_application: naming fixes, doxygen comments * fbt: changed `requires` manifest field behavior for app extensions * examples: refactored plugin apps; faploader: changed new API naming; fbt: changed PLUGIN app type meaning * loader: dropped support for debug apps & plugin menus * moved applications/plugins -> applications/external * Restored x bit on chiplist_convert.py * git: fixed free-dap submodule path * pvs: updated submodule paths * examples: example_advanced_plugins.c: removed potential memory leak on errors * examples: example_plugins: refined requires * fbt: not deploying app modules for debug/sample apps; extra validation for .PLUGIN-type apps * apps: removed cdefines for external apps * fbt: moved ext app path definition * fbt: reworked fap_dist handling; f18: synced api_symbols.csv * fbt: removed resources_paths for extapps * scripts: reworked storage * scripts: reworked runfap.py & selfupdate.py to use new api * wip: fal runner * fbt: moved file packaging into separate module * scripts: storage: fixes * scripts: storage: minor fixes for new api * fbt: changed internal artifact storage details for external apps * scripts: storage: additional fixes and better error reporting; examples: using APP_DATA_PATH() * fbt, scripts: reworked launch_app to deploy plugins; moved old runfap.py to distfap.py * fbt: extra check for plugins descriptors * fbt: additional checks in emitter * fbt: better info message on SDK rebuild * scripts: removed requirements.txt * loader: removed remnants of plugins & debug menus * post-review fixes
