style: Move all the fixup code into a StyleAdjuster struct.
This will allow reusing it from text styles, which we need for some corner
cases, like text-align: -moz-center and similar stuff.

stylo: support all overflow values
overflow:clip doesn't exist, it's just called clip internally. Renamed, and added the other missing values.
I also removed the overflow newtype -- no need for extra code bloat, and it's not protecting us from much.

Notify embedder when history changes
`WindowMethods::set_page_url` is only called when the embedder set the URL. It is not called when the page url is updated. I believe that instead we should just pass the URL to `head_parsed`.

Cleanup various modules and introduce generic types
Almost all the types in `values/specified` and `values/computed` share their `ToCss` implementations. The only reason they have duplicated code hanging around is a result of different specified and computed forms for types like `LengthOrPercentage`. This PR makes some of these types *generic* so that we could have a common definition and `ToCss` impl (`Parse` and `ToComputedValue` impls too, if possible).

Fix various build warnings
This removes six separate warnings when building servo. One of
the warnings was an unused mut, and the other were various dead code
warnings

Stylo: add -moz-border-*-colors support
In Gecko, we use double pointers to nsBorderColors to store -moz-border-*-colors.
We can simplify the implementation of computed value in Servo by using Option<Vec>.
As to passing computed values from Servo to Gecko, we might need to use some
binding functions (pre-added in the same Gecko bug, see Bug 1348173).
Note that we also added -moz-border-*-colors as sub_properties of the 'border'
shorthand, so we can make the 'border' shorthand reset -moz-border-*-colors
(See Gecko Bug 482692).
A bit refactoring of replacing all ["top", "right", "bottom", "left"] with PHYSICAL_SIDES
is included in this patch, since we've already had PHYSICAL_SIDES for a while.

we should skip these sub_properties while doing unit testing in Servo. The test part
should be convered by Stylo/Gecko already.
