It's not clear cut which code is responsible for canceling pending requests,
since the requests list is kept in vlr_subscr, but sending out Paging does
certainly not belong in the VLR. Place the requests cleanup in gsm_04_08.c.
Add to test_ms_timeout_paging() in msc_vlr_test_ms_timeout.c to verify that a
pending paging is canceled on IMSI Detach.

Currently, if there is no reply from the BSS / RNC, a subscriber will remain as
"already paged" forever, and is never going to be paged again. Even on IMSI
Detach, the pending request will keep a ref count on the vlr_subscr.
Add a paging timeout, as gsm_network->paging_timeout and in the VTY on the
'msc' node as 'paging timeout (default|<1-65535>'. (There is a 'network' /
'T3113' in OsmoBSC, but to not confuse the two, give this a different name.)
Add test_ms_timeout_paging() test to verify the timeout works.
I hit this while testing Paging across multiple hNodeB, when a UE lost
connection to the hNodeB. I noticed that no matter how long I wait, no Paging
is sent out anymore, and found this embarrassing issue. Good grief...

The target buffer in libsmpp is 16 bytes long, and snprintf() may omit the

osmo_strlcpy() is the safer (and presumably more optimal) choice.

In case of UMTS AKA, the Kc for ciphering must be derived from the 3G auth
tokens. tuple->vec.kc was calculated from the GSM algorithm and is not
necessarily a match for the UMTS AKA tokens.
So far we were always sending the Kc retrieved from osmo-hlr. If the 2G auth
algo is set to milenage, the 2G Kc coincides with the one derived from 3G
tokens, but if 2G is set to a different algorithm, the Kc received from the
osmo-hlr is not usable for ciphering when UMTS AKA was used for authentication
(on R99 capable GERAN and MS).
Implementation: To decide whether to use UMTS AKA derived Kc or the Kc from the
auth vector, use the umts_aka flag added to set_ciph_mode() in a previous
patch. Use osmo_auth_c3() to derive the GSM AKA Kc from the UMTS AKA CK and KI.

In case of UMTS AKA, the Kc for ciphering must be derived from the 3G auth
tokens. tuple->vec.kc was calculated from the GSM algorithm and is not
necessarily a match for the UMTS AKA tokens.
To decide (in an upcoming patch) whether to use UMTS AKA derived Kc or the Kc
from the auth vector, the set_ciph_mode() from vlr_ops needs to know whether
UMTS AKA is being used. This could possibly derived from the msc_conn_ref, but
all flags are already available in the vlr_lu_fsm and vlr_access_req_fsm. Hence
add a umts_aka flag to the set_ciph_mode() callback invocation. The VLR FSMs
thus decide whether UMTS AKA or GSM AKA is to be used during Ciphering Mode
Command, which makes more sense than re-implementing the same decision process
in the MSC.
I considered placing the Kc derivation in vlr_set_ciph_mode() and only tell the
MSC's set_ciph_mode() implementation the precise keys it should use, but the
RAN particulars, and whether a Kc is used at all, rather belong with the MSC.

a_iface_tx_cipher_mode() is a bit too far away from the VLR to be handling its
ciphering enums. Instead, construct the gsm0808_encrypt_info in the
msc_vlr_set_ciph_mode() callback.
Greatly simplify the sanity checking code: a_iface_tx_cipher_mode() no longer
needs to re-verify the presence of the gsm0808_encrypt_info contents.
Change-Id: Id46f9a513b555d0a481f7124c9984c2b5b196b3e
The bit shifting is performed in gsm0808_enc_encrypt_info(), and must not be
done when populating the gsm0808_encrypt_info struct.
Provide vlr_ciph_to_gsm0808_alg_id() to translate the enum vlr_ciph to the
GSM0808_* constants we need to put in the gsm0808_encrypt_info struct instead.
