(WebCore::guidToDatabaseMap): Use NeverDestroyed instead of DEFINE_STATIC_LOCAL.
(WebCore::guidForOriginAndName): Ditto.
(WebCore::DatabaseBackendBase::DatabaseBackendBase): Removed unneeded initialization
of m_guid, which is set in the body of the constructor explicitly anyway. Use emptyString.
Use unique_ptr for the values in the map. Use the add idiom instead of the get/set idiom.
(WebCore::DatabaseBackendBase::closeDatabase): Use the find/remove idiom instead of the
get/remove idiom.
(WebCore::DatabaseBackendBase::performOpenAndVerify): Use auto here to avoid having to
use the map type by name.

(WebCore::CachedFont::CachedFont): Don't initialize m_fontData to 0; unique_ptr will do that.
(WebCore::CachedFont::~CachedFont): Don't delete m_fontData. unique_ptr will do that.
(WebCore::CachedFont::ensureCustomFontData): Add a get.

(WebCore::createFontCustomPlatformData): Use nullptr instead of 0, and make_unique instead of new.
