Improves display list building performance by 50%-100% for small display

Don't re-add stylesheets to recompute vw/vh lengths
This is a follow-up to #9876. It avoids clearing and rebuilding SelectorMaps
when vh and vw units need to be recomputed. Instead it just dirties all nodes,
to force elements to be re-cascaded.
Filed #10104 for later follow-up work to dirty only affected nodes.

Fixes for compute_damage
A few changes:
* Make `compute_damage` short-circuit more, by skipping comparisons if they will only set flags that are already set.
* Update some obsolete comments.
* Add a bunch of missing properties to `compute_damage`.
* Set `RECONSTRUCT_FLOW` when `text-decoration` changes, because it can affect text fragment splitting/merging.
I believe this is all of the computed properties except for the animation properties. (I wasn't sure what to do with those.) After this lands I'd like to work on moving this information into `properties.mako.rs` so that this function can be auto-generated, and so that newly-added properties can default to setting all flags instead of none.

Add history information to mozbrowserlocationchange event
This is a change in the Browser API itself.
Before, on `mozbrowserlocationchange`, we would call `getCanGoBack()` and `getCanGoForward()`. Two asynchronous methods called on an event, which doesn't make much sense, especially because we already know on `mozbrowserlocationchange` if we can go back/forward. So here I'm adding 2 new properties to the event to tell if the iframe can go back/forward.
The way `event.detail` is defined also changed. Before, `event.detail` was a string (the new uri), now it's an object (`{uri:String,canGoBack:bool,canGoForward:bool}`).
This is one of the design flaw of the early Browser API: not using objects for the detail property, making it hard to extend the event payload.
So that makes this event not backward compatible. We can:
1. just don't care. It's up to the client to test if event.detail is a string or not if it needs to be compatible with Gecko
2. fix it in Gecko. The client will still have to test `event.detail` to make it compatible with older version of gecko
3. rename `mozbrowserlocationchange` to something else (`mozbrowserlocationchange2` ?)
Please advise.

layout: Skip layout traversals that obviously won't do anything.
This reduces CPU usage when mousing over simple pages (example.com). More complex pages (Wikipedia) still reflow a lot due to other bugs.
Additionally, this change causes Servo to stop painting the results of hit test queries. This is also a win for CPU usage.
This significantly improves #9999, though there's more that can be done. I'll leave it open in case @paulrouget thinks this PR isn't enough.

Remove HTMLCollectionElementsRevIter
It's almost a duplicate of HTMLCollectionElementsIter, aside from that its node_iter is a PrecedingNodeIter. We can simply use dynamic dispatch for node_iter instead of making it a concrete type.

Add Python 3 compatibility to Android symbol checker
Make the script that checks for undefined Android symbols compatible
with both Python 2 and Python 3, to allow for future updates to the
default system Python on our build machines.
I'd like to land this before https://github.com/servo/saltfs/pull/249.
We currently use Ubuntu 14.04 (an LTS release); Ubuntu is aiming for Python 3 as the default Python in the next LTS release, 16.04, and I'd like to have any scripts be ready for the transition.
Do we have a Python 2/3 compatibility policy?

Details ui
Requires a patch to rust-selectors, and doesn't currently recalculate the styles correctly (which is needed to make actual toggling work correctly).
Still trying to figure out what it takes to get style recalc to do what this needs.
