        The Database feature in the engine needs to support delegate calls for policy decisions and
        also provide notifications when origins and databases change their state.

        This patch also polishes off the missing features of the management API

        * page/Chrome.cpp: Implement the two UIDelegate methods
        (WebCore::Chrome::requestQuotaIncreaseForNewDatabase): Ask for more space to create a new database if it won't fit
        (WebCore::Chrome::requestQuotaIncreaseForDatabaseOperation): Ask for more space to complete an in-progress operation
        * page/Chrome.h:
        * page/ChromeClient.h:
        * platform/graphics/svg/SVGImageEmptyClients.h:
        (WebCore::SVGEmptyChromeClient::requestQuotaIncreaseForNewDatabase):
        (WebCore::SVGEmptyChromeClient::requestQuotaIncreaseForDatabaseOperation):

        * storage/Database.cpp:
        (WebCore::Database::openDatabase): Check to see if this database can be opened - the quota must be high 
          enough and if it isn't, the UIDelegate should have a change to bump the quota.
          Also update the UI-relevant details (display name and estimated size) upon successful opening of the database

        * storage/DatabaseDetails.h: Remove the version parameter as it is a programatic detail of a
          site database and is not important to API clients
        (WebCore::DatabaseDetails::DatabaseDetails):
        (WebCore::DatabaseDetails::isValid):
        (WebCore::DatabaseDetails::name):

        * storage/DatabaseTracker.cpp:
        (WebCore::DatabaseTracker::openTrackerDatabase): Tweaked the schema here - there was a horrible bug with the old schema that would
          prevent you from having two databases of the same name from two different origins.  Also simplify the origin-management schema
        (WebCore::DatabaseTracker::canEstablishDatabase): Added.  Does some estimated size vs quota checks, and asks the UI delegate for 
          more space if necessary
        (WebCore::DatabaseTracker::hasEntryForOrigin):
        (WebCore::DatabaseTracker::establishEntryForOrigin): Establishes a tracker entry for the given origin with the current default quota
          Also notifies the client of the new origin
        (WebCore::DatabaseTracker::setDatabaseDetails): Update the display name and estimated size for the given database
        (WebCore::DatabaseTracker::fullPathForDatabase): Tweak to add the ability to get the path without creating it - for management purposes
        (WebCore::DatabaseTracker::populateOrigins): Populate origins from the Origins table instead of the Databases table
        (WebCore::DatabaseTracker::origins):
        (WebCore::DatabaseTracker::detailsForNameAndOrigin): For API management
        (WebCore::DatabaseTracker::usageForDatabase):
        (WebCore::DatabaseTracker::usageForOrigin):
        (WebCore::DatabaseTracker::quotaForOrigin):
        (WebCore::DatabaseTracker::setQuota): Notify the client
        (WebCore::DatabaseTracker::addDatabase): Notify the client 
        (WebCore::DatabaseTracker::deleteAllDatabases):
        (WebCore::DatabaseTracker::deleteDatabasesWithOrigin):
        (WebCore::DatabaseTracker::deleteDatabase):
        (WebCore::DatabaseTracker::deleteDatabaseFile):
        * storage/DatabaseTracker.h:

WebKit/gtk:

        Keep it building with new client method

        * WebCoreSupport/ChromeClientGtk.cpp:
        (WebKit::ChromeClient::requestQuotaIncreaseForNewDatabase):
        (WebKit::ChromeClient::requestQuotaIncreaseForDatabaseOperation):
        * WebCoreSupport/ChromeClientGtk.h:
