Tag the ABD data pages so that they can be identified for exclusion from kernel crash dumps. Eliminating the zfs file data allows for significantly smaller crash dump files. Note that ZFS in illumos has always excluded the zfs data pages from a kernel crash dump. This change tags ARC scatter data pages so they can be identified from the makedumpfile(8) command. That command is used to create smaller dump files by ignoring some memory regions and using compression. It already filters file data from the VFS page cache and will now be able to exclude ZFS file data pages from the dump file. A corresponding change to makeumpfile(8) is required to identify ZFS data pages.
