RebornedBrain 467e973da2 [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
