gprs: Add expiry timeout for subscriber entries
Set the expiry delay after the subscriber has been deleted (e.g. by
freeing the MM context). If cancelled, the subscriber will be deleted
immediately and no timeout will be set. If the expiry time is set to
SGSN_TIMEOUT_NEVER, no timer will be started and the subscriber entry
will be kept until it is cancelled.
The following VTY command is added to the sgsn node:
- subscriber-expiry-time <0-999999> set expiry time in seconds
- no subscriber-expiry-time set to SGSN_TIMEOUT_NEVER
The default is an expiry time of 0 seconds, which means that the
subscriber entries are wiped out immediately after an MM context is
destroyed.
Note that unused MM contexts are not expired yet. Therefore the
subscriber will only be expired after a successful MM detach.
