4ba282c9c9 Fix bug #3433954: make containing_block available to layout_table so it can resolve percentage height specified on an absolutely-positioned table.

3776e49f02 Fix bug #3433840: <img style="display: table" src="..."> will crash if the image fetch completes before initial layout. 
A number of things wrong here:
1) The BOX_TABLE generated for the img shouldn't ever have been associated with the object (it should have been associated with the implied BOX_TABLE_CELL)
2) The layout engine's decision to treat BOX_TABLE/BOX_INLINE_CONTAINER with associated objects differently from non-replaced TABLE/INLINE_CONTAINERs seems wrong (looking though SVN history, it appears that this was introduced as part of the very first frames implementation, since replaced (twice!))
3) Now we fetch objects in parallel with building the box tree, we're open to this kind of race condition.
