IOSurface exploit.

Gets tfp0, works on all devices on 10.3.3 or lower.
Offsets included only for iPod 6G and and iPhone 5/5c on 10.3.3 though.

make

Without Xcode/macOS you'll at least want to point IGCC and STRIP to tools that can handle Mach-O's and build for iOS. You might also have to adjust ARCH and IGCC_FLAGS.
