Reviewed by James Robinson.

Source/WebCore:

Add -Wunused-parameter to WebCore targets. Apple's Mac compile already
warns on this and it's a common source of error for Chromium patches.

No new tests, should compile cleanly.

* WebCore.gyp/WebCore.gyp:

Source/WebKit/chromium:

* WebKit.gyp: Add -Wglobal-constructors. Don't add -Wunused-parameter because many of our API interfaces have named parameters with empty implementations.
* WebKitUnitTests.gyp: Add -Wglobal-constructors and -Wunused-parameter.

Tools:

* DumpRenderTree/DumpRenderTree.gyp/DumpRenderTree.gyp: Add -Wunused-parameter. Don't add -Wglobal-constructors because
there are lots of violations in these files.
