Merge 116333 - IndexedDB: LevelDB coding for bools is broken

Reviewed by Tony Chang.

Source/WebCore:

Code was appending to a pre-sized Vector, rather than using an
index setter. This caused uninitialized data to be written out.
Issue was detected on the Chromium side in http://crbug.com/126388

Tests: webkit_unit_tests --gtest_filter='IDBLevelDBCodingTest.*codeBool'

* Modules/indexeddb/IDBLevelDBCoding.cpp:
(WebCore::IDBLevelDBCoding::encodeBool):

Source/WebKit/chromium:

Added tests for encodeBool/decodeBool.
