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())

osmo_fd_register() is used to register socket file descriptors,
after registering a socket, there is no way to test if the socket
is still registered or actually registered at all.
This commit adds a new function osmo_fd_register_check() that can
be used to check in advance, if the socket fd is registered,
before performing further operations.

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.
