Don't use <linux/ext2_fs.h> if we can avoid it.
The ioctl constants have been globalized and moved to <linux/fs.h>.
Use a private copy of ext2_fs.h from e2fsprogs with the ioctl
constants removed for the data structures.
Do at least attempt backward compatibility for old kernel headers, but
no real hope of proper operation there...

syslinux_already_installed function will be used in both extlinux and
syslinux for checking if the boot sector has either the string
"SYSLINUX" or "EXTLINUX" in the OEMID field.

Put all the Linux ioctl header magic into a single shared file, and
try to make it as generally useful as possible.

Correct the implementation of block mapping using FIEMAP (as opposed
to FIBMAP).

Switch to consistent use of 64-bit sector pointers; this should enable
booting even for individual *partitions* larger than 2 TB. In order
to not slow down the boot too much, switch the initial load from an
enumeration to an extent map. This means the table gets larger (since
we have to assume the worst case), but it simplifies the Sector 1 code
(since we can push all the hard stuff into the installer), and will
speed up booting in the general case.

Thus we can share same command line options and reduce a lot of dup
code...
Seems like a big patch, but the changes are quite safe, no much logical
change.
