Rebased, tested and fixed by Holger Freyther. Release the transaction
only once the SMC is asking for the release and set the cb's to NULL
to catch a use after free early.
This has been rebased and fixed by Holger Freyther. The change of
the debug area was split out in a previous commit and the is_mt was
put back into the transaction code.
The transaction is now freed from the RELEASE_REQ sent by the SMC
layer and not inside the error path. When clearing the SMC instance
we also clear the callbacks.
This should and does happen as part of the trans_free/msc_release_connection
code. There is no easy way to determine that the lchan is now 'free' for other
things.. Let the transaction code sort this out. This code just needs to make
sure that transactions are always freed.
Use the code that is shipped inside the libosmogsm library. Right now
the signature (besides the static) and the implementation is the same.
This makes using the libosmogsm SMC code more easy in the near future.
For the gsm340_gen_oa we are now using a small wrapper to generate the
proper type and numbering plan.
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]
