Handling sparse files

This is similar to RFE 101191, but for versions of Linux that don't support lseek with SEEK_HOLE.

For those versions of Linux, is it possible to use ioctl with FS_IOC_FIEMAP ?
See the source code for BSD tar (not GNU tar) for details.

When I was opening the previous RFE, # 101191, I mistakenly thought that SEEK_HOLE works on RHEL 6 - apparently, SEEK_HOLE doesn't, but FS_IOC_FIEMAP does.
