`mach bootstrap` will finish succesfully,
but then segfault inside glibc while exiting.
It seems to have to do with the MarkupSafe library used by Mako;
delaying the Mako import from the top level to inside functions where it
is used avoids the problem.
(It seems to interact with the call to pip to install the Salt
requirements in the virtualenv, as commenting that pip call out
separately will also fix the segfault.)
Also, use the Mako installed in the Python virtualenv while running
packaging commands (instead of the one from the bundled zip file),
and cleanup imports in the package_commands.py file.
Used shared clips for overflow:hidden and CSS clip
Instead of passing down a complex clipping region to each item, used
shared clipping to handle overflow:hidden and CSS clips. In addition to
being more efficient, this should also fix quite a few issues related
to absolutely positioned elements.
One existing reftest is slightly modified to avoid tickling a quirk
with the way that WebRender rasterizes masks. We are working out how to
best express these combined masks with the API or need to. The change
does not affect the original subject of the reftest.

Fix various issues with overflow clipping
When dealing absolutely positioned items, we should use clip of our
containing block, even if our containing block doesn't itself establish
a new overflow clip. Additionally, we need to properly handle
assigning scroll root ids to fragments of inline elements.
We add a test for this behavior.

stylo: Bug 1341372 - Detect new transitions and let it run.
These are interdependent patches of Bug 1341372. We let animation-only restyle also work for RESTYLE_CSS_TRANSITIONS, and check if we need to update transitions by each transition property. If it is necessary to create/replace/cancel transitions, we create a SequentialTask for CSS_TRANSITIONS.

1. We need to call get_after_change_style, which is the computed styles
without transition rules, while process_animations.
2. If we have after-change style, we may replace the new computed values with
after-change style, according to whether we really need to update
transitions.
3. There are some cases we don't update transitions, so we need to early
return. might_needs_transitions_update() will check it first and it
will filter out most common cases.
4. needs_transitions_update() will check each property and existing running
transitions to make sure we really don't need to update transitions.
The logic of this function is similar with that of
nsTransitionManager::DoUpdateTransitions().
MozReview-Commit-ID: 2ccdPjgrxKz
It is possible to call get_after_change_style if there is no transition
rule. In order to avoid cloning the token computed values, we just return None.
The caller can use this Option to know which computed values should be
used.

We will add another function, needs_update_transitions, to check if we need
to update transitions, so factor this out.

Add one FFI to check if there is any transition in CSSTransitionCollection.
This will be used to check if we need to update transition and if we
should compute the after-change style.

For keyword-typed properties with aliases but no extra_specified values,
the storage of the specified and computed values could be the same,
since value aliases are resolved at parse time. But to prevent
computed_value::T::parse from recognizing these aliases, we keep the
specified and computed value types distinct.
Remove comment about text-combine-upright digits.
The digits value was never implemented and was dropped from the spec. Old issues like #13769 still discussed if this value should be implemented.

Upgrade to rustc 1.18.0-nightly (5f13a3b54 2017-04-15)
This version enables [struct field reordering][1] which brings the size of the types for specified values of some CSS properties under the threshold such that they shouldn’t be boxed anymore, making unit tests fail.
Simply unboxing them moves the test failure to Stylo’s unit tests, since the stable compiler used in that case does not do field re-ordering. Therefore, we manually reorder a couple fields to effectively bring this optimization to older compilers for a few specific types.
