Currently every subcriber object directly refers to the gsm_network
which contains a flag shared by every related subscriber
(keep_subscr). This adds a dependency on gsm_network even if only the
function defined in gsm_subscriber_base.c are used.
This patch adds a new struct gsm_subscriber_group which contains the
keep_subscr flag and a back reference to the network object. The
latter is not dereferenced in gsm_subscriber_base.c, so it can safely
be set to NULL when only that part of the gsm_subscriber API is being
used. It also changes that API to use gsm_subscriber_group instead of
gsm_network parameters.
Since there are some places where a pointer to the gsm_network is
needed but where only a gsm_subscriber is available, a 'net' back
pointer is added to the group struct, too. Nevertheless subscr group
and network could be separated completely, but this is not the topic
of this commit.

Currently the temporary string 'tmp' is freed before parts of it are
referenced. This lets address sanitizer complain when evaluating
strlen(imsi), where imsi points into the 'tmp' data block.
This patch moves the talloc_free to the end of the function and uses
a rc variable instead of using early returns.

Sadly there is no proper foreign key relationship on the tables
that related to the Subscriber. This means we can't use a DELETE
with Cascade and need to delete everything by hand. To make things
worse maybe the SMS/Paging code is still using the subscriber
making the operation more dangerous. I had added NULL checks for
sender_id/receiver_id at 30C3 so we should not crash in this
situation.

The test has been manually verified. Executing the select for
the subscribers showed:
sqlite> select * from Subscriber;
1|2014-03-23 12:12:46|2014-03-23 12:19:09|2620345||445567|1||0|
This created a subscriber with the right IMSI, MSISDN and has
it authorized.
Fixes: SYS#275
