Remove WrapPreserve3DList() and replaced it by creating a
nsDisplayTransform item for each transformed frame.
- Add an additional item for each top frame extending 3D context to
separate consequence contexts.
- Effective transform of a layer is the accumulation of ancestors in
the same 3D context.
- The layers creating new context and extended by children need a
temporary buffer if it's effective transform is not 2D.
- Clip rects are accumulated along the context chain.
- Visible rects of items are computed from dirty regions of the frame
creating the context and accumulated transforms.
- Bounds of items are computed from accumulated transforms and
accumulated bounds of the descent frames.
- Backface hidden is handled by compositor and BasicLayerManager.

This patch fixes various warnings from MSVC.
- Several "truncation from 'double' to 'float'" warnings, easily fixed by
appending 'f' to literals.
- Some "signed/unsigned mismatch" warnings. In read_tag_lutType(), MSVC is
apparently promoting the multiplication of a uint8_t and a uint16_t to an
int32_t, oddly enough. A uint32_t cast fixes the warning.
- |offset| was unused in qcms_data_create_rbg_with_gamma().
- A couple of "overflow in floating-point constant arithmetic" warnings
involving INFINITY in transform_util.c. There is some type confusion here --
in C99 HUGE_VAL is a double and INFINITY is a float. So the HUGE_VAL here
should actualy be HUGE_VALF. But, strangely enough, that isn't enough to
avoid the warning, I don't know why. However, it turns out that any
non-positive value for |interval| will have the same effect, so I just
removed all the INFINITY/HUGE_VAL stuff and used -1 instead.
It also fixes an ARM-only GCC warning.
- "'__force_align_arg_pointer__' attribute directive ignored". This is an
x86-only attribute. Instead of disabling it on x86-64, instead enable it on
i386 (which avoids enabling it uselessly on ARM).

There is an occasional driver crash on the nexus 6, and possibly other
Adreno 420 devices, which seems to occur in some circumstances after
calling glDeleteFramebuffers. Calling glFlush before
glDeleteFramebuffers prevents this. Add this workaround at least until
it is better known what is going on.
Make the FrameLayerBuilder remember for what region it has calculated
display item visibility, then recompute the visibility whenever the
dirty region it is passed to DrawPaintedLayer changes.
This means that the caller does not have to know the entire dirty region
that will be drawn for the transaction, but we can still optimise cases
where it knows some of the dirty region in advance.
This fixes a regression where MultiTiledContentClient's low-res display
port would not be painted if a smaller region of its high-res buffer had
already been painted that transaction, since the FrameLayerBuilder
had decided that most of the larger low-res region was invisible.

This is important because the previous repaint can be a no-op, and those don't trigger notifications.

There are many sub-classes of nsExpirationTracker. In order to distinguish them
nicely in the logging of timer firings, it's necessary to manually name each
one. (This wouldn't be necessary if there was a way to stringify template
parameters, but there isn't.)
