Patch by Alec Flett <alecflett@chromium.org> on 2012-06-21
Reviewed by Darin Fisher.

Source/WebCore:

Distinguish between an actual invalid IDBKey, and an array of
possibly-invalid subkeys by making IDBKey::isValid() check subkeys
if the type is an array.

Introduce a new way to transform an IDBKey into a
multiEntry-specific IDBKey, (IDBKey::createMultiEntryArray)
throwing out duplicates and invalid keys. Use it when storing
index entries for multiEntry indexes.

No new tests: existing tests have been altered to include new behavior.
