        Stubbing out everything required for a WebKit API for databases

        Biggest change in WebCore is that we passed around SecurityOriginData as the representation
        of a SecurityOrigin, instead of a String or a SecurityOrigin itself (which is an opaque object
        that has a different purpose besides just hanging on to the data)

        * WebCore.base.exp:
        * WebCore.xcodeproj/project.pbxproj:

        * platform/SecurityOrigin.cpp:
        * platform/SecurityOrigin.h:
        * platform/SecurityOriginData.h: Added.  Simple object to encapsulate the 3
          pieces of data in the SecurityOrigin tuple
        (WebCore::SecurityOriginData::SecurityOriginData):
        (WebCore::SecurityOriginData::protocol):
        (WebCore::SecurityOriginData::host):
        (WebCore::SecurityOriginData::port):
        (WebCore::SecurityOriginData::toString): Simple concatenation of the 3 components,
          colon separated

        * storage/Database.cpp:
        (WebCore::Database::Database): Use SecurityOriginData instead

        * storage/DatabaseTracker.cpp:
        (WebCore::DatabaseTracker::fullPathForDatabase):
        (WebCore::DatabaseTracker::databaseNamesForOrigin):
        (WebCore::DatabaseTracker::deleteDatabasesWithOrigin):
        (WebCore::DatabaseTracker::deleteDatabase):
        * storage/DatabaseTracker.h:

        * storage/DatabaseTrackerClient.h: Added.  For dispatching notifications up to WebKit
        (WebCore::DatabaseTrackerClient::~DatabaseTrackerClient):
