Since Web*LayerImpl inherit from LayerChromium that may call into its delegate from the destructor, we need to reset the delegate before calling that base destructor.

Would it be possible to make some webkit_unit_tests that exercise creating/destroying WebLayers just to check for crashes like this?

Added tests. Also fixed a couple of missing setNeedsCommit indicated by the test.

we prefer 2-clause nowadays, see Source/WebCore/LICENSE-APPLE (but put Google Inc on the top line and only include the current year)

Previous patch was breaking LayerChromiumTest (testing the wrong assumption). Fixed now.

Reopenning to reland once http://codereview.chromium.org/8404008 is in (that should fix it).

[James Robinson]

After that lands make sure that Source/WebKit/chromium/DEPS points to a chromium rev including the change so it gets picked up on the build.webkit.org bots.
