msc: allow only authentication without ciphering
So far the code did only auth+ciph or none. Add case handling for only
authentication without ciphering (basically just fill in the blanks).

Adjust authentication logic for Iu, move a log notice
Depending on conn->via_iface, fail upon missing auth for 3G.
Move the log notice saying "skipping auth" to gsm48_secure_channel() where
conn->via_iface is actually known.

Remove unused auth code and add comment
As commented in the code, the GSM_SECURITY_AUTH_FAILED path is never invoked by
the gsm48_secure_channel() function as it is today.
Note that the upcoming Iu auth will probably add a GSM_SECURITY_AUTH_FAILED
status. In that case, sending a LU Reject immediately may be desirable, but
arguably a bit of timeout could make life harder for auth attackers.
The code removed by this patch doesn't send out a LU Reject ever, since a call
to release_loc_updating_req() only releases the connection. To reject, a call
to gsm0408_loc_upd_rej() would be necessary, as seen in loc_upd_rej_cb().
And finally, if _gsm0408_authorize_sec_cb() doesn't do anything about anything,
the same loc_upd_rej_cb() will be run by a timeout and send a LU Reject
properly (as commented in the code).

GSM 04.08 message types: fix use of bitmasks
According to spec, the bitmasks for message types apply only for MM and CC
messages. However, various code used the bitmask even though no MM or CC
messages are involved:
bsc_msg_filter.c:
bsc_msg_filter_initial(): use bitmasked msg_type_mm for MM messages, use
unmasked msg_type for RR.
osmo_bsc_filter.c:
bsc_find_msc() and
bsc_scan_bts_msg(): use msg_type_mm for MM, unmasked for RR.
bsc_nat_rewrite.c:
bsc_nat_rewrite_msg(): use msg_type_cc for CC, unmasked for SMS.
bsc_ussd.c: don't mask, no MM nor CC involved.

GSM 04.08 message types: apply bitmask makros
In libosmocore, MM and CC message type bitmask makros were introduced.
Replace hardcoded bitmasks with these makros. Also replace the protocol
discriminator mask 0x0f with GSM48_PDISC_MASK.
Note: in some places, use of the bitmask is doubtful. This commit so far
applies the makros without changing anything.
Also note: the MM bitmask is hardcoded as 0xbf, but libosmocore also adjusts
the mask to the apparent de-facto standard of 0x3f, while the CC bitmask is
so far left unchanged at 0xbf. So where in doubt, use the CC bitmask.
