Remove the Proximity Events module.

We have no plans to implement Proximity Events[1] at this time. This patch
removes the module and the few hooks into WebCore it required.

The ENABLE_PROXIMITY_EVENTS flag has never been enabled in Chromium. Removing
the associated code should have no web-visible effect.

Fold WebCore/plugins/chromium into WebCore/plugins.

This patch folds PluginDataChromium into PluginData, and moves
PluginListBuilder into WebCore/plugins directly. The 'chromium'
directory can then be safely removed.

It is difficult to add new test cases for the V8 generator as
they don't pass the style guide.

Make CStringBuffer 4 bytes smaller on 64-bit.

I don't have any evidence that these are heavily used / stored in the heap,
but it seems like a plan to bring CStringBuffer in line with other WTF
variable-length containers, which limit length to 2^32.
