The problem is that the "interact" flag on these tests
causes that they are considered manual,
when they can be run automatically.
This patch removes the "interact" flag and uses "reftest-wait" class
to be sure that the test has been completed.
As a side effect of unifying url handling in part 1, url values in
unparsed property value and variable now works, thus this change.

This also removes the TABLE_ATTRS_DIRTY optimization. Constructing nsMappedAttributes isn't really expensive and we do it all the time anyway.

It's a bit unfortunate the use separate implementations of SpecifiedUrl for Servo
and Gecko, but they're different enough at this point that I don't think it really
makes sense to try to share everything. Splitting them out has some nice
simplifications as well.
I recognize that there's still some potential correctness issues for Servo using
the resolved URI in various places where the original URI may be the right thing,
but I've got too much on my plate to look into that for now.

Since -moz-element is moz only feature, the test case for -moz-element is
created under reftests/image-element folder.

I found this problem because I was debugging the failure of
layout/reftests/w3c-css/received/css-writing-modes-3/clearance-calculations-vrl-008.xht
with my patch for bug 1308876. It was failing because the red reference
box that was intended to be covered up was being mispositioned leftwards
by the width of the scrollbar, since we were not reflowing it when we
decided that the viewport did not need scrollbars. This patch fixes
that failure.
This led me to this bug, where
nsAbsoluteContainingBlock::FrameDependsOnContainer was incorrectly
testing conditions for when the values of 'top', 'right', 'bottom', and
'left' require reflow due to changes in the size of the containing
block.
The old code is incorrect in a number of cases, such as:
1. in RTL, with 'right: 100px', it will say that the frame does not
depend on its container's width since 'right' (offset-inline-start)
is a fixed offset and 'left' is 'auto'. However, since the
positioning is relative to the right edge, a change in container size
does require that the absolutely positioned element be repositioned
relative to the container's left edge.
2. In vertical-rl, again with 'right: 100px', it will make the same
mistake, since 'right' (now offset-block-start) is a fixed offset.
This is the case from the test I was debugging.
3. In vertical-rl with rtl direction and 'bottom: 100px', we will make
the same mistake because 'bottom' (inline-start) is fixed and 'top'
is 'auto', and we use 'bottom' rather than 'top'.
However, in cases (1) and (3) we actually avoid hitting the bug in these
simple-ish cases because ReflowInput::ShouldReflowAllKids() returns true
whenever IsIResize() is true, which means that
nsAbsoluteContainingBlock::Reflow doesn't even call
FrameDependsOnContainer. However, FrameDependsOnContainer should still
do the right thing because it's needed for
nsAbsoluteContainingBlock::MarkSizeDependentFramesDirty, which is only
used (from nsBlockFrame) when we reflow again for clearance or for
interruptible reflow. I haven't attempted to write a testcase for that
because it seems likely to require spending hours in the debugger trying
to trigger the right code.
This means that the only test that fails prior to the patch is
dynamic-offset-vrl-001.html, which exercises case (2), and also happens
to be the most similar to problem in clearance-calculations-vrl-008.xht.
This patch also makes the tests stricter so that we do optimize away
resizes in some cases where we're able to do so, such as
'left: 100px; right: auto' in RTL. (Or, rather, we would if it weren't
for the IsIResize() in ShouldReflowAllKids().)
