* Updated usbSendCommand() to make it send the command header first, and then the command block. Makes it easier for host applications to read and parse command data.
* Let usbSendCommand() take care of handling ZLT packets if required by any command block (only SendNspHeader at this moment), as well as logging status data via usbLogStatusDetail().
* Updated USB ABI specs doc.
* gamecard: added more comments, modified gamecardGetBundledFirmwareUpdateVersion() to fill a VersionType1 pointer instead of a u32, fallback to manually reading the gamecard certificate if fsDeviceOperatorGetGameCardDeviceCertificate() fails, updated GameCardFwVersion enum.
* title: tweaked conditions for some functions.
* usb: explicitly defined values for previously omitted struct members while initializing USB comms, imported libusb structs to make it easier to work with the USB BOS, added a few more comments and changed around some code.
* utils: tweaked the illegal filesystem character array to remove some chars that are actually allowed.
* 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.
* tik: check for common certificate availability before attempting to convert a personalized ticket to a common one. The raw common certificate chain data for the ticket signature issuer is now returned.
* usb: skip waitMulti call in the USB background thread if an invalid endpoint max packet size was received from the USB host in the previous while loop iteration.
Key area and certificate can be optionally appended and/or preserved, respectively. Trimming is supported.
Also added a bunch of ZLT packet related fixes to usb.c, as well as a function to properly cancel an ongoing file transfer.
Also increased the USB timeout again, since 1 second seems to be too low for gamecard transfers.
Big thanks to Whovian for helping me format that long system title list.
* 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...
