Changeset 95096 in webkit

Regressions in some layout tests from making border/mask/reflection nine-piece-image
parsing match the spec, which allows any of the pieces to be omitted and to also be
specifiable in any order.

When the higher level code suddenly allowed the image slices to be omitted, the fixup
for legacy compatibility for reflections and masks in the parseBorderImageSlice function
no longer happened because that function no longer got called.

The fix is to properly set the defaults to include the "fill" keyword, so the fixup is
applied to the NinePieceImages you create before you ever map anything in from the rules.

This also has the side effect of fixing -webkit-max-box-image-slice to actually dump as
"0 fill" instead of just "0", which is the correct initial value for this property.
