Really compare pointers to check if the one gsm_subscriber
is equal to the other... gsm_subscriber should be unique for
a given IMSI so comparing the pointers should be fine.
gsm_subscriber is now refcounted, the db backend is leaking
a lot less, db_get_subscriber will allocate the subscr record
now, subscr_* will look up a subscriber in the list of currently
active subscribers and add an ref to this one.
The db test cases pass, more testing will be when next to the bts
Call use_lchan early in allocate_loc_updating_req, do not directly call
rsl_chan_release but go through channel alloc to take the use_count into
account.
When a channel is allocated, start a timeout, when a lchan_use
is used the timer will be restarted, when the timeout fires
we will try to recycle or restart the timer.
