Dominik Riebeling b63d429c8f Provide dealloc function to ipodpatcher.
On Windows the sector buffer is allocated using VirtualAlloc, thus releasing
this buffer should be done using VirtualFree. Provide an additional function
for deallocating the buffer so users of ipodpatcher do not need to know about
this.
