implement removal of MSISDN

Add the first "official" way to remove the MSISDN from a subscriber entry, to
go back to 'MSISDN: none' like just after 'subscriber create'.

Add VTY command 'subscriber <ID> update msisdn none' to drop the MSISDN from
the subscriber. (Like 'subscriber <ID> update aud3g none')

Add DB_STMT_DELETE_MSISDN_BY_IMSI.

In db_subscr_update_msisdn_by_imsi(), allow passing a NULL msisdn, and if NULL,
call above delete SQL statement.
