nxdumptool/source/legal_info.c
Pablo Curiel 15431ec2c8 Many changes.
* 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.
