ino64 has gone into the tree. The stat structure layout
changed. 69921123490b99c2588b0c743bc4af32bbe6601c went into the tree a
while ago, but maybe recently enough to mess this up.

Commit the 64-bit inode project.
Extend the ino_t, dev_t, nlink_t types to 64-bit ints. Modify
struct dirent layout to add d_off, increase the size of d_fileno
to 64-bits, increase the size of d_namlen to 16-bits, and change
the required alignment. Increase struct statfs f_mntfromname[] and
f_mntonname[] array length MNAMELEN to 1024.
