Implement white-space property(pre)

In order to support line-break by new-line character,
Fist, calculate new-line character's position.(fn flush_clump_to_list)
Second, split box(which includes new-line character) and do line-break.(fn scan_for_lines)
Use &str instead ~str in make_url
Dumping display list levels to rust log
Move servo-android-glue submodule to mozilla-servo.

For some reason the webconvforge organization is the cause of many API
failures. They seem to be sporadic but no one has any idea why it
happens.

Make ref tests check the pixels for differences and emit a difference file.
The compositor needs to not process a Paint message after it has started
shutdown or it will crash creating a native layer. This happened during
reftests using -o to emit a PNG of the backbuffer and then exiting early.

layout: Destroy flows properly under `display: none`.

Fixes a crash on http://en.wikipedia.org/wiki/South_China_Sea

It plants a destructor bomb on flows so that this can't happen again.

Fix DOM binding generation to use proper output directory.

The WebIDL move wasn't quite correct. Now the dependencies and output directory are all correct.
script: Avoid an allocation when getting attribute data.
