* Inject settings and global instances as dependencies to the ExternalStoreMedium instances. This includes the local wiki domain, so that wfWikiId() calls are not scattered around. * Create ExternalStoreAccess service for read/write logic. * Deprecate the ExternalStore wrapper methods. * Add some exception cases for bogus store URLs are used instead of just giving PHP warnings and failing later. * Make moveToExternal.php require the type/protocol to decide which ExternalStoreMedium to use instead of assuming "DB". * Convert logging calls to use LoggerInterface.
