Add function for allocating CTRL connection to public headers and
replace call to previous static function with it. Add doxygen docs for
this function.
It's useful if we need to allocate ctrl connection but don't need to
bind to any interfaces: when we act as ctrl client.

My recent logging patch was merged to master a bit too soon. Accomodate the
request for naming that matches the general "LOG" prefix instead of "LOGGING".
libosmocore will not be backwards-compatible with the few commits from
change-id I5c343630020f4b108099696fd96c2111614c8067 up to this one. This and
following commits are backwards compatible with those before that short window.

Commit 812ba6dc63
"logging: centrally define ctx and filter indexes"
Removed definitions, which causes older e.g. openbsc and osmo-pcu code trees to
fail to build against a newer libosmocore. Re-introduce the legacy definitions
to redirect to the new ones and re-establish backwards compatibility.
The GPRS_* constants used to be defined in gprs_msgb.h, but since that header
also includes logging.h, rather place the legacy shims in logging.h next to the
other ones.

MSCR and CBQ3 are Release 1999 additions to the Control Channel Description IE
of SI3.
Assuming that no-one is using the spare bits, this will not cause any code
conflicts.
In the R99 struct, spare1 and spare2 are in different places, so rather rename
them to spare_1 and spare_2 to make sure we get a compiler barf *if* anyone
tries to use them with the wrong structure.
Adjust the spec reference to TS 44.018; TS 04.08 Figure 10.5.33 is replaced by
TS 44.018 Figure 10.5.2.11.1 which is right there in the named Section
10.5.2.11, so drop the explicit reference.
Motivation: the R99 Control Channel Description defines MSCR to indicate
whether the MSC is R99+ or not. To use UMTS AKA on GSM networks, we want to
indicate that our libmsc is capable of R99, like OsmoSGSN already does.
CBQ3 is merely added for completeness, no particular use case in mind.

It is too easy for calling code to use the same filter and context indexes for
different filters and structs. For example, openbsc's IMSI filter and libgb's
GPRS_BVC filter both fall on index 1 even though there are plenty more indexes
to choose from. To alleviate this, have one central definition here, sort of
like ports.h does for VTY and CTRL port numbers.
Add static asserts to make sure the indexes fit in the available array and bit
mask space.
Calling code like openbsc.git and osmo-pcu need adjustments and/or should move
to using these enum values instead of their local definitions.
Taking this opportunity to also prepare for a split of struct gsm_subscriber in
openbsc into bsc_subsciber and vlr_subscriber with appropriate separate filter
index constants for both subscriber types.
Include previous LOG_FILTER_ALL in the LOGGING_FILTER_* enum, and replace its
use by (1 << LOGGING_FILTER_ALL).

when the lapd core is in state LAPD_STATE_SABM_SENT, and the
retransmission counter exceeds (link down) lapd_t200_cb() will
send an RELASE_INDICATION and an MDL_ERROR_INDICATION to L3.
This action is done before the state is processed. This seems
to be no problem with standard retransmission counts (n200),
but may cause timing problems that lead to deadlock states when
custom timer configurations are in use. (Ericsson RBS).
This commit moves the functions calls for sending the indications
mentioned above to the very end of the if branch to relax the
timing again. (See lapd_t200_cb())

milenage_gen_vec() has parameter ordering of (..., auts, rand_auts, rand).
osmo_auth_gen_vec_auts() has (..., rand_auts, auts, rand), but actually feeds
args in the same order, so that its rand_auts becomes auts, and its auts
becomes rand_auts.
Interestingly enough, API user osmo-gen-vec.c also adheres to this misordering
and in turn passes auts for osmo_auth_gen_vec_auts()'s rand_auts and vice
versa, so that it matches milenage_gen_vec().
So both the implementation (milenage_*) and the API user use the same ordering,
just osmo_auth_gen_vec_auts() and osmo_auth_impl{ .gen_vec_auts() } in-between
have the argument names swapped.
Any current user of this API would need to adhere to this swapping or will not
get successful AUTS resolution to a SQN. So the least impact fix is to rename
the args without any actual functional change.
So swap the names rand_auts and auts for osmo_auth_gen_vec_auts() and
osmo_auth_impl{ .gen_vec_auts() }. (Also adjust API doc ordering)

When calculating a re-sync vector using AUTS, osmo-gen-vec used to print
SQN.MS + 2, the new SQN after vector generation, labeled 'SEQ.MS'.
Firstly, s/SEQ/SQN.
Secondly, print SQN.MS as umts.sqn - 2, which is the actual SQN recovered from
the AUTS. As explained in the comment, SQN.MS + 1 is used to generate the
vector, and then umts.sqn is increased a second time to indicate the next SQN.
With AUTS calculated from SQN.MS == 23, the output was:
AUTS success: SEQ.MS = 25
Output now:
AUTS success: SQN.MS = 23, generated vector with SQN = 24, next SQN = 25

GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same
procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS
to our osmo_auth_gen_vec_auts() API.
According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14
bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2
and AUTS being the V = 14.
It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But
writing 16 bytes to a GSUP struct is a potential problem when passing in a 14
byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer.
The API implies the length, so far to be 16, so passing in a 14 byte buffer to
GSUP would require copying to a larger buffer first.
Fix this by using a length of 14 for AUTS everywhere instead.
This constitues an ABI breakage, we may handle it as a "fix before an official
release", otherwise we need a version bump.
The OAP protocol document has also been updated, needs an update in the
osmo-gsm-manuals as well.

After subchan_demux.c in libosmo-abis, osmo-bts/common/vty.c and openbsc's
gtphub_test.c, more places would like to count the llist items (mostly unit
tests). Instead of proliferating numerous local implementations, add here.
NOTE: other than the previous llist_len() implementations, this one returns an
*unsigned* length, which might need some adjusting of current callers.
Call this llist_count() rather than llist_len() to highlight the fact that this
is actively iterating. This also avoids a potential naming conflict when
library versions mismatch.
