gprs: Support cancellation type
The cancellation type that is part of the UpdateCancellation message is currently ignored. This patch adds the missing glue between the existing GSUP and GMM support. If the type is not present or has the value updateProcedure the subcriber and MM context are siliently removed. Otherwise, a message with cause 'implicitly detached' is sent to the MS. Since the real cause is not known (the specification neither added a cause IE nor defined a static cause value), the MS may get the real cause in the following AttachRej. Added VTY commands: - update-subscriber imsi IMSI cancel update-procedure - update-subscriber imsi IMSI cancel subscription-withdraw the old form without the cause is no longer supported.
