* fix missing aeskey select for card2 save decrypt
* fix old/new cart media being swapped
* fix 1 MiB save chips / blockmap type 2
* move cart save wearleveling/crypto to separate file
* try 2nd wearlevel header on fail + minor fixes
* save_ctr: zero out savectx before reading fallback header
This commit looks a lot bigger than it really is, I noticed a couple spots where with these issues so I ran a regex to find all possible occurrences and switched all that could be, after manually ensuring it was actually correct
Using sizeof on the buffer (as long as the buffer is a char *array*, not a pointer!!) greatly reduces the chance of something having the wrong size because of a later change to the buffer, notably a couple snprintfs were missed in the UTF_BUFFER_BYTESIZE change
- removed most of lodepng's optional features
- lodepng now uses the already existing CRC32 code instead of using its own copy
- fixed GIC interrupt priority
BPS standardization edits.
* Clean up headers.
* Move crc32.c to /crypto/.
* Rename beat.c to bps.c and move it to /system/ with the rest of the non-3DS file formats.
Allocate memory for Source and Target files when possible.
Last-minute BPS improvements.
* BPS fails more gracefully on error, freeing memory and showing a more detailed message.
* BPM no longer deletes the folder it patches to - that should be up to the user.
* BPM is scanned before patching to figure out the total output file size for a more accurate progress bar.
Add IPS support.
