Etienne Dechamps 5cb63a57f8 Implement the truncate_range() inode operation. ...

This operation allows "hole punching" in ZFS files. On Solaris this
is done via the vop_space() system call, which maps to the zfs_space()
function. So we just need to write zpl_truncate_range() as a wrapper
around zfs_space().

Note that this only works for regular files, not ZVOLs.

This is currently an insecure implementation without permission
checking, although this isn't that big of a deal since truncate_range()
isn't even callable from userspace.
