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...
