In libosmocore, my patch was merged to master a bit too soon. To accomodate the
request for naming that matches the general "LOG" prefix instead of "LOGGING",
a fixup was committed to libosmocore. Adjust for that.
Original patch: change-id I5c343630020f4b108099696fd96c2111614c8067
The fixup: change-id I424fe3f12ea620338902b2bb8230544bde3f1a93

The LCHAN and BTS filter contexts are actually never used, so drop them until
someone adds them properly.
For now use only LOGGING_{FILTER,CTX}_VLR_SUBSCR. Some of these will change to
_BSC_SUBSCR once struct bsc_subscriber is introduced, and later on, struct
gsm_subscriber will be replaced by vlr_subscriber so that the names will match.

To be paranoid, catch a NULL subscriber and/or bts in
subscr_update_expire_lu(): print an error log and avoid segfault.
(I'm not sure this would really happen in a normal situation.)
During aggressive testing of Paging timeout, I came across this segfault in
msc_release_connection() when conn->expire_timer_stopped is set but
conn->subscr is NULL, at the subscr dereference after:
if (conn->expire_timer_stopped)
subscr_update_expire_lu(conn->subscr, conn->bts);
I brought this situation about by a fabricated Paging fault, i.e. in
gsm48_rx_rr_pag_resp() return 0 and don't call gsm48_handle_paging_resp() at
all. Thus conn->subscr is still NULL when expire_timer_stopped is 1.
When looking at CM Service Request handling, the conn->subscr is set before
setting expire_timer_stopped = 1, which is a saner thing to do. But without my
mad 'return 0', there is in fact no way to have a NULL subscriber there.
It looks like all other code paths already do the same, but it's not that
obvious (e.g. _gsm48_rx_mm_serv_req_sec_cb()). So rather catch this case of
NULL conn->subscr, and while at it catch NULL bts as well.

Since ce9fec3e896571835ac5bfd2980d6836f2b29f0d libosmocore ignores
parameters to log_vty_command_* functions. Hence parameter of
logging_vty_add_cmds() is ignored too. As we depend on much later
libosmocore version anyway, we can simplify code somewhat by removing
parameters which will be ignored anyway.

Postfix the ran type to clarify the purpose.
Because of the new support of the Iu ran type, there are 2 functions to allocate a mm ctx.
For Iu it's sgsn_mm_ctx_alloc_iu(). For gb it should be named in the same way.

Parse the longer UMTS res from the extended Auth Response Parameter IE.

Check conn->subscr against NULL.
gsm0408_rcv_cc() dereferences many conn members without checking presence: the
bts and lchan members may be expected to be NULL in the ongoing MSC split and
3G developments.
But the conn->subscr is initially NULL, so an MS sending a CC message before
something like a LU or CM Service Request will result in a segfault. Prevent
that.
Note: the upcoming VLR will be more restrictive on what messages are processed,
this is a "backport" to the situation on current master.

It is one of these changes that should have never worked but did
for a long time. Only recently a corrupted GTP message was seen.
The code in ccd2312d10 tried to
solve the right problem but was deeply flawed.
* Make the code operate on the copied message and not the original
one that is deleted by the underlaying layers on return
* Add an out variable to determine if the msgb should be deleted
and assume that by default it will be deleted.

It is generally not a good idea to add more and more external
dependencies unless absolutely needed. autoconf-archive is a good
example of that, as we need to update all build machines, and older
OpenEmbedded versions do not appear to have (the right?)
autoconf-archive recipe. Provide local copy of necessary m4 files to fix
the build there.
The dependency to autoconf-archive was introduced in Change-Id

in gprs_gmm.c:gsm48_rx_gmm_ra_upd_req the variable reject_cause
is not initalized, which is ok, since it gets initalized before
the jump into the "rejected" path. However, the compiler still
throws a warning. This commit fixes the problem by preinitalizing
the reject_cause to GMM_CAUSE_PROTO_ERR_UNSPEC

In some cases, when successive mobile originated calls are made, the LAPDm UA
message gets lost because the channel is relased to early. Too overcome the
problem we do not send release indications immediately. Instead a flag will be
set and the message stored and sent on the next TCH-RTS-IND.
This commit adds the required flag and the msg-buffer to struct gsm_lchan.
