Nfc: add basic Mifare DESFire support (#1024) * Fix TextBox word wrap behavior * Wrap width is 120 pixels, not 140. (140 is larger than the screen!) * Glyph width already includes spacing; don't add 1 additional px * When starting a new line, include wrapped glyph width in new line_width. * Call canvas_set_font before text_box_insert_endline so that glyph width is calculated using correct font. Previous approach worked somewhat well using default TextBoxFontText but this version is more robust, particularly when using TextBoxFontHex. * Add basic Mifare DESFire reading, file/app browser * Fix build with APP_ARCHIVE=0 * Add bool type to flipper_format * Add ability to save and load DESFire card data * Skip over NfcSceneDeviceInfo when viewing saved DESFire info * mf_df_clear: don't leak master key settings key versions * When opening a DESFire card from Archive, retain UID emulation behavior * rm unnecessary \r\n * show Popup instead of leaving view in bad state * Move NfcReaderRequestData out of union This makes it safe to emulate DESFire/EMV without clobbering card data. * Display saved DESFire cards via NfcSceneDeviceInfo * Display and save file metadata even when contents are missing This can happen when a file doesn't allow unauthenticated reads (see the call to mf_df_parse_read_data_response in nfc_worker.c).

[FL-2274] Inventing streams and moving FFF to them (#981) * Streams: string stream * String stream: updated insert/delete api * Streams: generic stream interface and string stream implementation * Streams: helpers for insert and delete_and_insert * FFF: now compatible with streams * MinUnit: introduced tests with arguments * FFF: stream access violation * Streams: copy data between streams * Streams: file stream * FFF: documentation * FFStream: documentation * FFF: alloc as file * MinUnit: support for nested tests * Streams: changed delete_and_insert, now it returns success flag. Added ability dump stream inner parameters and data to cout. * FFF: simplified file open function * Streams: unit tests * FFF: tests * Streams: declare cache_size constant as define, to allow variable modified arrays * FFF: lib moved to a separate folder * iButton: new FFF * RFID: new FFF * Animations: new FFF * IR: new FFF * NFC: new FFF * Flipper file format: delete lib * U2F: new FFF * Subghz: new FFF and streams * Streams: read line * Streams: split * FuriCore: implement memset with extra asserts * FuriCore: implement extra heap asserts without inventing memset * Scene manager: protected access to the scene id stack with a size check * NFC worker: dirty fix for issue where hal_nfc was busy on app start * Furi: update allocator to erase memory on allocation. Replace furi_alloc with malloc. * FuriCore: cleanup memmgr code. * Furi HAL: furi_hal_init is split into critical and non-critical parts. The critical part is currently clock and console. * Memmgr: added ability to track allocations and deallocations through console. * FFStream: some speedup * Streams, FF: minor fixes * Tests: restore * File stream: a slightly more thread-safe version of file_stream_delete_and_insert Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
