    fuse: add support for SEEK_HOLE and SEEK_DATA through lseek()

    The Linux FUSE kernel module has gained support for passing SEEK_HOLE
    and SEEK_DATA on through lseek(). This can greatly improve performance
    when working with sparse files.

    Linux FUSE introduced support for lseek() with version 4.5. The commit
    in mainline Linux is 0b5da8db145bfd44266ac964a2636a0cf8d7c286.
