This adds mmap64() to bionic so that it is possible to have large offset passed to kernel. However, the syscall mechanism only passes 32-bit number to kernel. So effectively, the largest offset that can be passed is about 43 bits (since offset is signed, and the number passed to kernel is number of pages (page size == 4K => 12 bits)).
