29e5af2064 BKTR rewrite: part 1.
This is a mess. It won't build, so don't bother trying.

c1e3dc719f More NCA changes.
* Made ncaGenerateEncryptedFsSectionBlock() entirely private. There's no point in keeping it public.

* Moved NCA FS section context initialization into its own function, ncaInitializeFsSectionContext().

* Hash data boundaries are now checked while initializing each NCA FS section context, using ncaFsSectionValidateHashDataBoundaries(). Both ncaValidateHierarchicalSha256Offsets() and ncaValidateHierarchicalIntegrityOffsets() have been removed.

* Improved hash region access detection in _ncaReadFsSection() by implementing ncaFsSectionCheckHashRegionAccess().

* ncaGetFsSectionHashTargetProperties() is now used in pfs.c, romfs.c and bktr.c to retrieve the properties from the target hash layer.

* Updated sanity checks in pfsInitializeContext(), romfsInitializeContext() and bktrInitializeContext().

2c4ddac4c6 nca: skip hash layer crypto operations if needed.
ncaInitializeContext(), _ncaReadFsSection() and ncaGenerateHashDataPatch() were all updated to reflect this change.

SHA3-256 support is still missing.

8d8f19b229 nca: SparseInfo support (part 1).
Proper CTR IV and context are generated to decrypt the SparseInfo IndirectBucket. More to come at a later time.

278cb5c72a Some changes.
* nxdt_includes: renamed VersionType1 to Version and tweaked it to add the application_version struct, renamed VersionType2 to SdkAddOnVersion.

* gc_dumper: use utilsGeneratePath() to truncate generated filenames to safe filesystem limits. Thanks to n0tw0rk for reporting the issue and testing the changes!

* nxdt_host.py: fixed a string formatting issue that made it impossible to unpack data from the SendFileProperties command block under certain circumstances.

* gamecard: modified GameCardKeySource to add a value field, added GameCardFlags_HasCa10Certificate flag.

* utils: utilsGeneratePath() no longer adds a dot on its own if it's not part of the provided extension string.

f526d4e6f4 Crypto changes.
* 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).

f82d7a3db4 Small code refactor (part 2).
* 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.

4c0c7d2c56 Small code refactor.
* 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.
