Before this patch, there's an edge case where we may drain a pushed float (with
a stale position), and then discover that it won't fit in the current block (so
we push it and leave its position untouched), but we still inadvertently
include its rect in the current block's overflow areas. This means we're
feeding stale/bogus position into the overflow areas, which can make them
unnecessarily huge.
This patch accounts for this by only considering overflow from floats that we
actually successfully placed, in ReflowPushedFloats.
(Also: this patch removes a stale bit of documentation about aLineLayout being
possibly-null in AddFloat. In actuality, AddFloat has a fatal assertion that
mandates that this arg is non-null.)

The helper is going to be used in a later part.
I don't add the physical version ComputedPhysicalBorder() deliberately
because I don't want to promote the usage of physical coordinate.

`aState.mBCoord` already includes block-start border and padding, so we
wrongly add the block-start border and padding twice when computing the
border-box content block-size. This patch fixed it, and rename
`contentBSize` variable to make it clearer.

In Bug 1527949, we are going to add block-end padding of the block
container to aBEndEdgeOfChildren, so we need this patch in order to
query GetLogicalUsedPadding().

Also, swap the argument order of aBEndEdgeOfChildren and aDisplay,
because I'm going to make ConsiderBlockEndEdgeOfChildren() a
nsBlockFrame method, and make its arguments the same order.
This patch shouldn't change the behavior.

I assume nsIFrame::IsAbsolutelyPositioned()'s callers really want to
check whether a frame is a real abspos frame, not just check a frame has
a abspos style. This could potentially change the behavior, but I feel
its the right thing to do.

This will prevent growing them when introducing fit-content(<length>).
This can _almost_ be derived, if it wasn't because of the quirky stuff.
I think the macro is probably good enough for now but let me know if you
disagree.

This patch adds the struct as a parameter to various functions.
The struct is cached in ReflowInput so that we don't need to pass it
down to the internal method where nsIFrame::ComputeSize() is called.
In the subsequent patches, we'll use it to revise the implementation of
flex container's flex base size resolution, and size overrides.

This allows supporting image-set(), etc, and simplifies the bullet frame
code significantly, too thanks to two changes:
* Instead of manually managing the image request, use the CSS image
loader, with the `REQUEST_REQUIRES_REFLOW` flag, to handle image
loads correctly. This didn't exist when this code was initially
implemented, but we can nicely use it now.
* Instead of re-implementing another WebRender command-builder thing,
we can just reuse the nsImageRenderer code.

Making them non-overflow containers is valid but then we can't just
append them to mFrames since that'll put them on the last line which
may result in some lines in-between the pulled child and its
continuation. That violates the invariant that in-flow continuations
in the same parent must be on consecutive lines (unless they are
overflow containers in which case they need to be on the
[Excess]OverflowContainers lists).
(The crash happens because if we push the lines in-between the two
continuations to the OverflowLines, then we won't find the 2nd
continuation on the first line of OverflowLines.)
(Note also that this change triggers the assertion in
DrainExcessOverflowContainersList, and depends on bug 1680406
to fix that and merge the lists.)

Precomputing the skipBEnd bit is odd / wrong. Using the PreReflow
version causes no regression, and allows us to simplify the code.
It also reverts the test annotations added to bug 1675376 which were
caused by the extra argument to GetLogicalSkipSides() somehow.

That avoids going all the way to the first continuation to call ResolveBidi on
it. This shaves a bunch of time when there are a lot of pages.
This is more problematic than it seems specially when there's no bidi, because
in the "bidi not enabled" case we never remove the flag, which is bad. When
bidi is actually enabled we usually have done the resolution already.

This removes virtually all the time under ConsumedBSize. See the comment for
what ensures the correctness of the cache: Basically, we refresh the cache for
a frame continuation every time we reflow it, which means that when next
continuations go look for it it should be up-to-date (we rely on that already
because we're looking at the content rect).

It's straightforward to determine which writing mode is required to pass
to ComputedLogicalMargin() by looking at any subsequent method called on
the margin.
For example, if we see
```
ComputedLogicalMargin().BStartEnd(wm);
```
the writing mode needed to pass to `ComputedLogicalMargin()` is `wm`.
