* 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.
* Improved patch and add-on content title ID verification against a base application title ID.
* Implemented linked lists in TitleInfo structs, which make it easier to deal with multiple patches / add-on contents belonging to the same application.
* TitleApplicationMetadata elements are retrieved with titleGetApplicationMetadataEntries() and used by the UI to display title entries. An 'is_system' filter argument is used to determine which kind of metadata should be retrieved. These are ordered by ID (system titles) or alphabetically (user applications) using qsort().
* Added TitleUserApplicationData struct, which is populated when an user application is selected.
* Tweaked titleRefreshGameCardTitleInfo() behaviour a little bit. Now returns true whenever there are title info changes, so the UI can reload the list.
* Temporarily commented out title info logging from titleInitialize().
* Fixed decrypted key retrieval from the NCA key area for patches with titlekey crypto removed.
* Implemented a very small menu to select a title to dump.
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.
