* gsm_util now uses caller-allocated data (rather than callee-allocated)
* correctly parse destination address
* parse (but not transcode) non-default encodings of SMS
* reject SMS to unknown destination number
* resolve target subscriber id and store incoming SMS (without header) in 'sms' table
What we're now missing is the sending part, i.e. a regular task iterating over
all pending SMS and trying to deliver them. Also, check for pending SMS once
we get a LOCATION UPDATE.
Remove the callbacks from gsm_network for now. A set of different
callbacks will be back. E.g. when the paging is completed, when the
Q.931 like call handling is there...
Remove var's or move them into #if 0, remove unused stuff that looks
like we do not need it anytime soon or #if 0 them, move stuff around.
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
