Merge 116562 - IndexedDB: call abort handler when there are problems committing
https://bugs.webkit.org/show_bug.cgi?id=85841

Patch by Alec Flett <alecflett@chromium.org>; on 2012-05-09
Reviewed by Ojan Vafai.

No new tests. Every existing test that calls commit() is testing
the success side of this, and this only throws when there are
LevelDB errors, which is exactly what we're trying to diagnose
with this patch.
