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.
