[FL-3810] Felica emulation (#3673)
* Moved some structs and defs from poller to generic felica * Buffer size increased for transferring more data * Felica HAL Tx function implemented * Some structs and fields for listener * Raw listener implementation * Added new event for felica activation * Proper config fot listener added * Moved some structs from poller in order to use them in listener too * New function for calculating MAC * Listener data structures and function definitions * Private listener functions implementation added * Raw felica listener logic implementation added * Fix total sector count both for poller and listener * Defined type for write handlers * New logic for write operations added * Removed old commented code * Splitted read logic into several separate functions * New type added and some fields to instance * New logic of read command implemented * Defines added for response codes * Functions moved to private namespace * Function visibility changed and some cleanups * Update felica_listener.c, felica_listener_i.c, and felica_listener_i.h * Some type adjustments * Moved frame_exchange function to private namespace * Error handling added * Function to get data_ptr for write request added * Missing declaration added * Add processing of nfc errors * write_with_mac is a local variable now * Adjustments to MAC calculation logic * Values replaced with defines * Update nfc_transport.c with felica logic * Sync felica poller added for unit tests * Felica unit_tests and data dump added * Fixed proper reading of MAC_A block when it is 1st * Macro definitions for MC added * Function simplified * More defines * CRC check for incomming packets added * Readonly logic adjusted * Block write validation adjusted * New logic for ID block writing * Some cleanups * New logic of moving across the block list with different element length * Some cleanups * Adjusted requires_mac logic to cover all blocks needed * Cleanups and renaming * New block list validation logic * Block list logic iteration simplified * Some asserts and checks added * Replaced MC[2] checks with macros * Marked def values as unsigned * Removed old code * Removed commented function declarations * Changed protected block in felica test card dump and adjusted tests * Fixes after merge * Moved defines to header * Now we allocate memory for max possible response pack in any case * Some renaming and documentation * Bump api symbols * Set feature to emulate full for felica * Removed 'More' button and added MoreInfo feature which adds this button back * Types renamed * Removed unnecessary code * Reformat comments * Fixing missing signatures * Replaced crash with error log and return value * Format doxygen comments Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
