Subject: Add functions to read and write the AUPD (flash update) image. 
 "--read-aupd aupd.bin" will read (and decrypt) the AUPD image, and
 "--write-aupd aupd.bin" will write (and encrypt) an image.  Also fix a bug in
 the "diskmove" function which corrupted the AUPD image when a bootloader was
 installed.  So in order to manipulate the aupd image, you need to restore a
 clean firmware partition, and install the bootloader with this version of
 ipodpatcher.  Decryption functions based on the description and sample code
 at http://ipodlinux.org/Flash_Decryption
