[Pki-devel] [PATCH] 0144..0146 Move IRequest extdata-related constants

The attached patches relocate / redefine some constants that are used as keys when setting or getting IRequest extdata attributes. In some cases this removes duplicate constants or string literals. In other cases it actually defines a new constant. In all cases the key now uses a constant defined in IRequest, which is the appropriate place. This is refactoring work undertaken as part of GSSAPI support. Thanks, Fraser
