* Implemented RSA-2048-PSS + SHA256 signature verification.
* Refactored RSA-2048-OAEP decryption steps to use mbedtls function calls.
* Implemented NCA header main signature verification.
* Replaced Björn Samuelsson's CRC32 algorithm with the hardware accelerated CRC32 checksum calculation from libnx (latest commit with support for calculation in blocks).
* Rewrote mutex handling throughout the code to use a small, macro-based scoped lock implementation.
* Removed extern variables from common.h - launch path management is now completely handled in utils.c.
* Updated NpdmSystemCallId_Count to reflect changes introduced in 12.0.0.
* Added NcaMainSignatureKeyGeneration enum.
* NCA main signature moduli are now retrieved from FS .rodata at runtime.
* Simplified lock management in usb.c by using a single global mutex with scoped locks instead of three different r/w locks.
* Updated FatFs to R0.14b.
* Enabled 64-bit LBA support in FatFs to potentially support custom eMMC replacements / resized USER partitions in the future.
* Updated LZ4 to v1.9.3.
* Fixed typos.
* USB gamecard dumper PoC now only dumps the Initial Data area.
* Updated to-do list.
* Refactored keydata handling.
* Sealed NCA KAEKs are now generated at startup, and NCA key area entries are now decrypted by keysDecryptNcaKeyAreaEntry(), reducing the number of calls to spl functions.
* The eTicket RSA device key is now retrieved and decrypted at startup. RSA-OAEP wrapped titlekeys are now decrypted by keysDecryptRsaOaepWrappedTitleKey().
* Renamed titlekek -> ticket common key throughout the codebase.
* Added NcaKeyAreaEncryptionKeyIndex_Count and NcaKeyGeneration_Max enum values to nca.h.
* Proper usage of strcasecmp() in some functions.
* Moved syscall hint checks from keys.c to mem.c.
* Define illegal FS characters as an array rather than a char pointer.
* Services are now initialized before the CFW type checks.
* Fixed pcv/clkrst service initialization.
* Implemented additional thread safety and logfile output to service functions.
* Slightly tweaked running service checks.
* Added proper Markdown documentation for the USB ABI.
* Avoid performing any crypto operations on null NCA key area entries.
* Added commented out code to handle the aes_ctr_ex NCA key area entry, just in case we end up needing it at some point.
These files will be modified to slowly add features from the nxdumptool rewrite codebase.
This commit effectively makes it impossible to build the previous PoC. The code from each PoC will be reused, though, so it hasn't been removed.
* Remove references to the secondary Nintendo Extended BFTTF because it's identical to the first one.
* Use format attribute in functions that need it (and fixed errors I made in the past).
