* 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.
