Holger Hans Peter Freyther b809866be5 tbf: Learn and propagate the TLLI changes due a new P-TMSI
During a routing area update a new P-TMSI was assigned. During
the PACKET CONTROL ACK on the DL we notice the change of TLLI
but didn't propagate this. This means that a Routing Area Update
Complete was only sent after a new RACH request.

Addresses:

Holger Hans Peter Freyther 5464c9baf2 tbf: Have one imsi field and assign it through a function
Have one IMSI field per TBF and assign through a function call.
The IMSI should be used to look-up the TBF on the SGSN->PCU
direction.

Holger Hans Peter Freyther 34f6e5ebe6 tbf: Make tfi private and update the code
All logging code that used tbf->tfi is now using tbf_name to
print the the TBF. External code is now using tfi() which is
inlined and should result in the same code being generated as
before (+debug code that can be stripped).

Holger Hans Peter Freyther 474685e26e tbf: Make the tlli "private" and update the updating code
Now all updates to the tlli/tlli_valid are in one place. If we
implement the policy to update the matching/linked TBF we can
now to do it in a single place. Add a todo item for that as I
am waiting for feedback from the mailinglist.

Holger Hans Peter Freyther bd449f57a7 tbf: Create tbf_name and use it in log statements
This is like gsm_lchan_name and should be used in log statements.
This way we can easily change the information that is printed and
we know how to search things. The other part is that direct use
of tfi/tlli is removed which will allow us to make them private
and at the same time start to resolve the "tlli" updated in many
places.

Not old log statements are changed yet. This will done whenever
a bad log statement is seen on the console...

Holger Hans Peter Freyther 870c601f1d tbf: TODO:Mark TLLI changes as todo item in the code
The TLLI can change when a new P-TMSI is assigned to the phone,
e.g. during a (periodic) routing area update. When the TLLI
changes we need to update all TBFs and maybe even register the
timing advance for the new TLLI..

Holger Hans Peter Freyther 6b88cddc21 bts: Simplify rcv_resource_request, remove logically dead code
tbf = find
 if (tbf) {
   tbf_free(tbf);
   tbf = NULL;
 }
 if (!tbf) {
   code...
 }

Remove the if (!tbf) and indention as the tbf is always to be
NULL.

Holger Hans Peter Freyther 15bb1a2a51 misc: Change the logging for the tbf and what to log
TLLIs got printed as TBF. Fix that but also rename things to
TFI. The TFI is not required to be unique per BTS but it is
the indicator we use right now.
