Summary

Most of the changes are little touchups:

  • Add a subroutine, compare_magic, for comparing the magic field of a dump header.
  • We now use the dumpextent field of the trailing dump header to locate the leading dump header.
  • DoRegularFile needs to do reads in multiples of the device's sector size, but with compressed dumps we may need to do a read that doesn't end on a sector boundary.

I don't have operator precedence memorized for these ones. Can we add a pair of parentheses around (compress || isgzipdump)?

  • - use parens to make an expression easier to parse
