Expecting OsmoBSC to send a RESET to the SMLC implies that the virtual SMLC
stays quiet until a RESET is received. Add flag to configure RESET behavior of
BSSMAP-LE.

The BVC-RESET / BVC-RESEt-ACK follow a set of rules:
* Signaling BVCI=0 never has a CellId in BVC-RESET nor BVC-RESET-ACK
* Any BVC-RESET or BVC-RESET ack in BSS->SGSN direction must have CellID
* Any BVC-RESET or BVC-RESET ack in SGSN->BSS direction must NOT have CellID
Let's adjust our test expectations accordingly.
This will break tests against "latest", but the amount of work-arounds
needed in this code outweighs the benefit.

The existing BSSGP_Emulation is built around the assumption that every
instance of BSSGP_Emulation only servers one signaling-BVC and one
PTP-BVC. While this is true for osmo-pcu at this point (BTS-colocated
PCU), other BSS/PCU implementations differ.
In general, there can always be any number of PTP BVC (one per cell)
next to the signaling BVC (one per BSS). Let's represent this in
BSSGP_Emulation so we can create more comprehensive tests.

This allows NS_Emulation to react to changes of the underlying

Both osmo-bts and osmo-pcu are switching to PCUIFv10 soon, so let's
use the new version by default. For older (latest) IUT versions
not supporting PCUIFv10, one would need to override this module
parameter in {BTS,PCU}_Tests.cfg.

This is a step to prepare the NS_Emulation for operating on top of
Frame Relay, not just UDP/IP. We replace the NS_CodecPort (mapping to
a IPL4asp) with a newly introduced NS_Provider_CT, specifically a
NS_Provider_IPL4_CT.
This change removes any IP specific bits from NS_Emulation and moves
it into the newly-created NS_ProvideR_IPL4.

Unlike osmo-pcu, osmo-bts does check length of the messages received
over the PCU interface, so I7a532d7abff8af354e40c5d706bb882efc6f905f
caused all the related test cases in ttcn3-bts-test to fail.
Reverting it is not a solution, because we cannot maintain different
padding attributes for two different protocol versions. Let's add
a wrapper function that would call enc_PCUIF_Message() and append
padding depending on the configured protocol version. In addition,
let's add a module parameter that would allow us to (optionally)
disable padding for ttcn3-pcu-test.
This change makes all broken PCUIF specific test cases pass.

There is no reason whatsoevery why a L3_Templates.ttcn file should
ever include types from RLC/MAC. This creates a dependency nightmare.
The type for which ts_RaCapRec is written (MSRACapabilityValuesRecord)
originates from titan.ProtocolModules.MobileL3 so it's completely
unclear how any of that ever related too RLC/MAC.

This in turn means Osmocom_Gb_Types doesn't need to depend on
GSM_RR_Types anymore, which is particularly ugly as the latter
now depends on RLCMAC_*, creating a long chain of dependencies.

If test calls RTPEM_bind twice, the previous socket is kept open
(ConnId 1) while the new one is assigned to the the expected ConnId for
RTP/RTCP packets received (ConnId), however, if remote was already
sending packets, it may happen that the port still receives those with
ConnId=1, which may make test fail with message:
"Received unexpected type from RTP"

My initial assumption was that we can skip redundant '0'B bits or
even '00'O octets in the Mobile Allocation IE, and thus reduce
the overall size of this element. Unfortunately, this is wrong.
3GPP TS 44.018, section 10.5.2.21 clearly states that the Mobile
Allocation IE contains a bit-string of size NF, where NF is the
number of frequencies in the cell allocation. If NF % 8 != 0,
then '0'B padding bits must be appended to make it octet-aligned.
In other words, if the cell allocation contains let's say 13
frequencies, but a hopping timeslot makes use of only a small
fraction of it (e.g. 4 first channels), we would still need to
transmit at least 13 bits (+padding), including all redundant
bits and octets.
In RLC/MAC frames though it's not required to make the bit-string
octet aligned, so we need to send exactly NF bits without padding.
In order to achieve that:
a) add MA length field to INFO.ind (record PCUIF_InfoTrxTs);
b) ajust the existing test cases to use this field.
It's safe to merge this change as the related patches have not
been merged to osmo-pcu and osmo-bts yet.

Unfortunately, the existing implementation [1] is somewhat
incomplete and unfriendly to build templates on:
- some fields holding integer numbers defined as BITx,
so we would have to do bit2int() / int2bit();
- some bit-map fields defined as octetstrings;
- some fields are not decoded at all (raw octetstrings).
Let's work this around by defining a minimalistic implementation
of (RR) Assignment Command with all mandatory and some optional
fields. Reuse some IEs directly from MobileL3_RRM_Types.
