There's filefrag already, and that works, but, it's output is very inconsistent between various OS release versions, and it has already meant that we'd needed to adjust tests to account for these little but insignificant changes. A lot more work than useful. It's even more changed in el9. This adds `scoutfs get-fiemap FILE` and prints out block extent info with flags that we care about as an abbreviated letter: U for Unwritten, L for Last, and O for Unknown (as in, "offline"). The -P/--physical and -L/--logical options turn off logical or physical offset display, in case you only want to see the offsets in either units. You can pass -b/--byte to display offsets and lengths in byte values. The block size will then be obtained from fstat() of the queried file (4096 for scoutfs). I've removed all uses of filefrag from our scoutfs tests. Xfstests still calls it but their internal diff takes care of that issue. Where needed and appropriate, the tests are adjusted so that the output of `scoutfs get-fiemap` is as close as it can to what it used to be, so that reading the test results allows the quick view of what might have been going wrong. There are some output strings I have not bothered to update because there's no real value to updating every output string to match, and we just adjust the golden file accordingly.
