lukem e3ba61f9f3 Incorporate fix by iedowse @ FreeBSD to allow disks with large numbers of 
cylinder groups to work correctly, with minor modifications by me to work
with our FFS_EI code.  From the FreeBSD commit message:

	The ffs superblock includes a 128-byte region for use by temporary
	in-core pointers to summary information. An array in this region
	(fs_csp) could overflow on filesystems with a very large number of
	cylinder groups (~16000 on i386 with 8k blocks). When this happens,
	other fields in the superblock get corrupted, and fsck refuses to
	check the filesystem.

	Solve this problem by replacing the fs_csp array in 'struct fs'
	with a single pointer, and add padding to keep the length of the
	128-byte region fixed. Update the kernel and userland utilities
	to use just this single pointer.

	With this change, the kernel no longer makes use of the superblock
	fields 'fs_csshift' and 'fs_csmask'. Add a comment to newfs/mkfs.c
	to indicate that these fields must be calculated for compatibility
	with older kernels.
