* AES: moved CTR initializing/updating functions here from nca.c.
* BKTR/RomFS/PFS: check if we're dealing with a NCA with titlekey crypto and the titlekey hasn't been retrieved.
* BFTTF: use void pointers for output font data.
* Mem: Only exclude Unmapped/Uo/ThreadLocal/Reserved memory pages if dealing with FS.
* NCA: use content type context pointers inside NCA contexts to manage ContentMeta, ProgramInfo, Nacp and LegalInfo contexts.
* NCA: added 'written' bool elements to patch structs to indicate patch write completion.
* NPDM: remove unnecessary inline functions, generate PFS patch right after changing ACID data, add a pfsWriteEntryPatchToMemoryBuffer wrapper.
* PFS: added PartitionFileSystemFileContext and related functions to deal with NSP headers.
* ProgramInfo: removed unnecessary inline functions.
* Save: added commented code to dump a full system savefile - will probably use it down the road.
* Tik: added support for volatile tickets (thanks to @shchmue and @Whovian9369!), added a rights ID string representation to the Ticket struct, clear Volatile and ELicenseRequired flags in conversions to common tickets.
* Title: added a function to calculate the number of titles (current + siblings) from a TItleInfo block.
* Utils: added a function to generate a dynamically allocated path string using a prefix, a filename and a extension.
* Removed explicit offset checks throughout all the code.
* Codestyle fixes.
* Updated to-do.
From now on, I'll delete code from the legacy codebase directory as soon as specific features from it are rewritten... Because it's a mess to navigate.
* Codestyle fixes.
* NCA contexts for NCAs with titlekey crypto will now be generated even if the ticket can't be retrieved, in order to be able to use ncaReadContentFile() with them.
* Moved aes128XtsNintendoCrypt() out of nca.c.
* Updated disclaimer in all source files.
* Improved signed payload (certificate, ticket) handling.
* Prefer strlen + strcmp over strncmp whenever possible.
* Simplify header file inclusions in source files.
* Simplify background gamecard thread logic.
* Properly close keys file handle if there's a key parse error.
* Update NcaKeyGeneration enum.
* Small changes to save.c/h.
Will probably have to revert some USB changes...
