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.

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).

Now all updates to the tlli/tlli_valid are in one place. If we

now to do it in a single place. Add a todo item for that as I
am waiting for feedback from the mailinglist.

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...

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..
