Several issues are addressed in this commit:
* Inline flows now bubble up their absolute descendants instead of
making the inline flow the containing block for them. (In the future,
we will need to make the inline flow *sometimes* be the containing
block for them, but for now it improves sites to unconditionally
bubble up.)
* Fragments now look at their inline fragment context to determine
whether they are positioned.
* Inline flows now push the stacking-relative position of the absolute
containing block down to their inline-block fragments.
* Inline absolute hypothetical fragments can be containing blocks.
* Fixes the logic in
`containing_block_range_for_flow_surrounding_fragment_at_index`. The
condition to determine whether fragments are positioned was inverted!
* `Descendants`/`AbsDescendants` has been refactored in order to become
more friendly to inline absolute containing blocks in the future.
Improves the inline position of the green drop-down arrow in the Google
SERPs. (The block position is still wrong.)

These are caused by page_root being empty.
@jdm, I think it was #6874 that introduced these. I'm seeing them all the time when starting Servo on Reddit with memory profiling enabled. With this patch applied they go away.

Snapshot probably could also work as today's nightly (I wasn't able to download the latest one due to choppy internet), there isn't any plugins churn I know of

Didn't check that setting debug flags actually did anything.
Haven't written much Rust so this feels more verbose than necessary.

`CGAbstractMethod` takes a couple boolean parameters, among others:
* `extern`: will mark the method as `unsafe` and `extern`
* `unsafe`: will wrap the method body in an `unsafe` block
Passing both as `True` should not mark it as `unsafe` twice.
Example from a generated `HTMLCollectionBinding.rs`:
Before:
```
unsafe extern fn get_length(..) -> u8 {
unsafe {
// code here
}
}
```
After
```
unsafe extern fn get_length(..) -> u8 {
// code here
}
```

If you'd like me to change this message for specific types, please write something like this: "Trusted - Cannot calculate Heap size for Trusted" so that it would be easier for me to replace them through a script :)

There were two bugs here: (1) relative position applied to
scanned/unscanned text fragments independently of the container element
that applied that relative position, causing double-counting; (2)
relative position applied to inline block fragments independently of the
wrapped block itself, causing double-counting.
Closes#7067.

This patch makes Servo unconditionally strip whitespace before text run
scanning (assuming that the `white-space` property allows it). Whitespace
stripping during reflow is now only used for handling whitespace at the ends of
lines; reflow now never attempts to handle ignorable whitespace.
Many CSS tests pass now. There are some new failures, however.
The following reference tests now fail due to a pre-existing bug whereby
whitespace is used to calculate the position of inline hypothetical boxes for
elements with `display: inline; position: absolute`:
* `absolute-replaced-height-036.htm`
* `vertical-align-sub-001.htm`
* `vertical-align-super-001.htm`
The following reference tests fail due to a pre-existing bug whereby we don't
handle `font-size: 0` properly in inline reflow:
* `font-size-zero-1.htm`
* `font-size-zero-2.htm`
The following reference test fails due to the fact that it relied on our
incorrect insertion of whitespace to make room for the black background:
* `inline-formatting-context-007.htm`

Snapping the top-left and bottom-right corners separately can cause a rectangle to change size or even become empty when offset by a subpixel amount. Instead, this patch snaps the top-left corner, then snaps the size to a whole pixel amount, so any rectangle of a given original size will always have the same snapped size.
Fixes#7152. r? @pcwalton or @glennw
