Expressions with percentages may be negative or positive at computed value time.
So, we can only clamp lengths at computed value time, which is what the other
browsers do.
Don't use mem::uninitialized() for making calc values
We had code relying on `nsStyleCoord::set()` being leaky (like it was
before we patched up the calc bindings). Added `nsStyleCoord::null()` for
this use case since it's not possible to construct directly anymore.

Handle specialized serialization of <position> in basic shapes
Fixes#13083
We temporarily broke basic-shape serialization in #13042 when 4-value positions were implemented, since I didn't want to increase the scope of that PR too much.
This fixes it.

Handle row borders in border collapsing logic.
<!-- Please describe your changes on the following line: -->
Handle table row border when collapsing borders for a table row. The row border is combined with the cell's border using the already implemented conflict resolution logic.
This is a screenshot of the following test:
```html
<!doctype html>
<html><body>
<style>
table {
border-collapse: collapse;
}
tr {
border: 1px solid black;
}
</style>
<table>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
</table>
</body>
</html>
```
<img src="https://dl.dropboxusercontent.com/u/10962672/Screenshots%20Servo/servo_tr_border_collapse.png"/>
The top border is missing, but I think that's a different bug, since it also does not show up when the border is in the cells, and not the rows. Also, when debugging the border collapsing structures, they seem ok (the top border seems to be there). I can look at that bug in a separate issue (or in this one too if you prefer).

`Stylist` contains separate hashmaps for important and normal declarations,
but typically a given block only contains declarations of one importance.
Before this commit, there is an optimization where
a `PropertyDeclarationBlock` is only inserted in the corresponding map
if it has a non-zero number of declaration of a given importance.
With CSSOM, `PropertyDeclarationBlock` is gonna have interior mutability:
the importance (priority) of a declaration could change.
This optimization would become incorrect when the block is missing
in a hashmap where it should be.
This commits removes the original optimization, and replaces it with
a slightly weaker one: if a block doesn’t have any declaration
with the importance we’re cascading for, skip selector matching.
