Consistent border-spacing truncation.

With this change, we'll treat border-spacing pretty much like margins,
as far as block fragmentation is concerned. That is, we'll now truncate
them at fragmentainer boundaries. This also includes border-spacing
before repeated table headers, which affects quite a few tests in
fragmentation/ and printing/. Set border-spacing to 0 in some tests (and
compensate by adding padding to the table cells where it makes sense, so
that we don't affect the block-size of the contents too much (which
would require bigger test rewrites)).

Also add new tests that use non-zero border-spacing. They are marked as
tentative, since exact behavior here is undefined.
