According to GSM 04.08, 4.4.2 "ASN.1 data types":
the USSD-DataCodingScheme shall indicate use of
the default alphabet using the 0x0F value.
Previously, the UnstructuredSS Request messages with not
default alphabet were not being handled. Let's fix this.

According to the GSM 04.80 (version 5.0.0) specification Annex A
"Expanded ASN.1 Module "SS-Protocol", the maximum size of a USSD
OCTET STRING is 160 bytes.
Thus according to ETSI TS 123 038 (version 10.0.0) specification
6.1.2.3 "USSD packing of 7 bit characters", in 160 octets, it's
possible to pack (160 * 8) / 7 = 182.8, that is 182 characters.
The remaining 6 bits are set to zero.
This change defines both mentioned values:
- GSM0480_USSD_OCTET_STRING_LEN 160
- GSM0480_USSD_7BIT_STRING_LEN 182
keeping the old MAX_LEN_USSD_STRING 'as is' due to compatibility
reasons. Now the new value is used for ss_request structure, while
old one is still used for deprecated ussd_request structure.

According to GSM 04.80 Section 2.5 'Release complete' Table 2.5,
the 'RELEASE COMPLETE' message payload is optional, so let's drop
the length check in gsm0480_decode_ss_request() for this type.

If the length provided in the patcket exceeds the buffer length,
tlv_parse() returns -2 but leaves tlv.val and tlv.len initializd.
Many callers of tlv_parse() do not check its return value, but
rely on TLVP_PRESENT() to see if a particular TLV was parsed
successfully. By clearing tlv.val and tlv.len we make it less
likely that those callers will use an overlong TLV length value.

Add gsm48_encode_ra() which takes appropriate struct as [out] parameter
instead of generic buffer. Using uint8_t buffer instead of proper struct
type prooved to be error-prone - see Coverity CID57877, CID57876.
Old gsm48_construct_ra() is made into tiny wrapper around new
function. The test output is adjusted because of the change in function
return value which was constant and hence ignored anyway.

To send a Ciphering Mode Command, we may need to derive a Kc from UMTS AKA
tokens. gsm_milenage() derives Kc from 3G tokens, but also derives an SRES.
For SRES, it requires an OPC, which may need to be derived from OP first. All
we need is a Kc, so we could feed a zero OPC ... but to simplify the function
call for cases where just a Kc is required, separate the c3 function out from
gsm_milenage(), as osmo_auth_c3(). Obviously call osmo_auth_c3() from
gsm_milenage() (meaning that osmo-hlr's 55.205 derived auc tests still cover
exactly that implementation).

Some Abis/RSL messages such as "Release Indication" contained 3 extra
bytes from an L3 Information header which should not be there according
to specs in GSM 08.58 (section 8.3 "Radio link layer management
messages"). Other RSL messages were affected by the same issue, except
for "Establish Indication", which had already a workaround in
send_rslms_dlsap.
This commit fixes the issue in a generic way, removes the "Establish
Indication" and fixes the test accounting for the bug, as it otherwise
fails after applying the changes.

On systems with GNU/Linux kernel older than 3.17 (Debian 8 "jessie" for
example) the osmo_get_rand_id() would always return failure due to
missing getrandom() syscall.
To support such systems, let's add fallback code which uses GnuTLS
library. It can be disabled explicitly via '--disable-gnutls' option at
compile-time, otherwise ./configure will fail if both getrandom() and
GnuTLS are not available. When building with '--enable-embedded' the
fallback is disabled automatically.

According to
https://www.gnu.org/software/automake/manual/automake.html#Libtool-Flags
the libraries supposed to be added to *_LDADD or *_LIBADD
while *_LDFLAGS should contain additional libtool linking
flags. Previously we used both. Let's unify this and move all the
libraries into proper automake variable. While at it - also add
libosmocore.la for tests to LDADD since all the tests link against it
anyway.

The function is a wrapper on top of getrandom() (if available via glibc) or
corresponding syscall. If neither is available than failure is always
returned.
It's intended to generate small random data good enough for session
identifiers and keys. To generate long-term cryptographic keys it's
better to use special crypto libraries (like GnuTLS for example)
instead.
As an example it's used to replace old insecure random number generator
in osmo-auc-gen utility.

libosmocore offers the ipa API as general IPA Multiplex, which is e.g. used for
GSUP in osmo-msc. Looking at talloc reports, it is confusing to see "Abis/IP"
as msgb comment, because osmo-msc does not have an Abis interface.
Rename to "IPA Multiplex" as a more general description.

lapd_est_req() function could be called on uninitialized lapd link
(before lapd_dl_init() and after lapd_dl_exit() functions) due to
invalid usage on higher levels.
In order to prevent using uninitialized lapd link, we should set
LAPD_STATE_NULL state for lapd_datalink in lapd_dl_exit() function.
So all messages for lapd_datalink in null state will be unhandled by
lapd_recv_dlsap() function and lapd_est_req() function will not be
called before lapd_dl_init() function where lapd link state is changed
to idle.

When doing UMTS AKA with AUTS, it can be interesting to know the SQN.MS that
was encoded in the AUTS. The only way to know this is to provide it as a
separate out-parameter from milenage_gen_vec_auts(), because the SQN.MS from
AUTS stored in umts.sqn is immediately modified non-trivially by
milenage_gen_vec(). Add sqn_ms to struct osmo_sub_auth_data to retain SQN.MS
even after a vector was generated.
Use this to print out SQN.MS for 'osmo-auc-gen -3 -A'.
Adjust test suite expectations.
