not supporting PCUIFv10, one would need to override this module

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.

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.

This change introduces new version 10 specific extensions, in
particular: the frequency hopping parameters of each timeslot.
These parameters are used to compose Channel Description IE
in the packet resource assignment messages.
In order to maintain backwards compatibility with version 9 of
the PCUIF, and thus to still be able to run test cases against
the latest release of osmo-pcu, I kept the old parts of the
INFO.ind and gruoped them together with the new records
into union 'PCUIF_InfoTrxs'.
During decoding, the content of this union is resolved by the
TITAN's RAW codec itself, depending on value of the 'version'
field. During the encoding, it's the responsibility of the
API user to set a proper field of the union. I implemented
both f_PCUIF_ver_INFO_{Trxs,PDCHMask} helpers for that.
Version 9 is kept as default, so this change can be merged
independently of the actual implementation. We can bump
it and remove the compatibility glue once the new versions
of both osmo-bts and osmo-pcu are released.

So far the naming is so that the EUTRAN_NeighborCell sounds like it reflects a
single E-ARFCN, while in fact it contains a list of E-ARFCNs. In 3GPP TS 48.018
it is more accurately named "Neighbor Cells", in plural.
There is another "list layer" that allows repeating these lists of E-ARFCNs,
which the spec names Repeated Neighbor Cells, i.e. have a list of (=repeat) the
lists of E-ARFCNs.
Repeated Neighbor Cells = {
// first cells list
Neighbor Cells = {
cell descriptions = {
{ e_arfcn = 1, meas_bw = 3 },
{ e_arfcn = 2, meas_bw = 3 },
{ e_arfcn = 3, meas_bw = 3 },

Neighbor Cells = {
cell descriptions = {

{ e_arfcn = 5, meas_bw = 3 },
{ e_arfcn = 6, meas_bw = 3 },
},

...
}
Adjust the naming of the SI2quaterRestOctets members to more closely resemble
this structure, adopting the naming in 3GPP TS 48.018:

because it is really a collection of multiple E-ARFCNs
EUTRAN_NeighborCells -> EUTRAN_RepeatedNeighborCells

"Repeated Neighbor Cells".
