This patch makes methods of FramePropertyTable and FrameProperties to be
simple template wrapper functions. Then it converts all references to
FramePropertyDescriptor to use "void" parameter to simulate the current
unsafe behavior.
SmallValueHolder is used for storing small values like int32_t, float,
which can fit in the size of a pointer directly, and thus no lifetime
management is needed.

Specifically on Windows nsIWidget::SetTransparencyMode can result in sync painting.
So we give nsContainerFrame::SyncWindowProperties a sync or async option and use the view manager post pending update infrastructure to flush SyncWindowProperties calls async.
Known problem:
It would cause infinite loop if there is any line break happens inside
ruby base or annotation, or the width of container is not enough for
the widest pair/span. This might be fixed in bug 1098272.
Specifically:
* move all the frame dump methods to nsIFrame. Especially nsFrame::ListTag
was annoying, often requiring a cast to nsFrame*.
* print common values in the same order for all types of frames
* print fluid continuations as "next-in-flow=%p" and non-fluid as
"next-continuation=%p" (as before)
* print the style-context more compactly, e.g.
"[sc=0x7faa6b60e0a0] pst=:first-line" becomes
"[sc=0x7faa6b60e0a0:first-line]"
* suppress printing visual/scroll-overflow rects when they are identical
to mRect and do the same for nsLineBox::List where it was especially
hard to see which lines actually had real overflow
* fix a bug that printed the child list name at the far right when the
principal list was empty (making it hard to see)
* print the address of child lists (other than the principal list) to
help debug frame list property bugs
* s/NS_IMETHODIMP/void/
"new nsFrameList()" becomes "new (shell) nsFrameList()".
"delete list" becomes "if (list) list->Delete(shell)" - note also that
an additional assertion was added that list is empty when deleted.
"nsAutoPtr<nsFrameList> list(StealSomeFrames())" becomes
"AutoFrameListPtr list(aPresContext, StealSomeFrames())"
Specifically, this wasn't done for the OutsideBullet list which was
destroyed by the property destructor, potentially after the entire
frame tree was gone. Now we'll assert that the property destructor
isn't called.
Use SafelyDestroyFrameListProp when destroying PushedFloat and
OverflowOutOfFlows frame lists since it's more robust.
Destroy [Excess]OverflowContainers frame lists if they exist, regardless
of the IsFrameOfType(nsIFrame::eCanContainOverflowContainers) bit
(since the oveflow continuation tracker doesn't check that before
creating these lists -- this was the source of crash bugs before
that bit was added to ColumnSetFrame).
Assert in SetPropTableFrames that the property doesn't exist, because
if it does the property destructor will run, which isn't supported.
