RAW_NS used previous a single TTCN3 port for a single UDP port
(source/listen side).
This has the limitation that only a single NSVC could be tested for a
local UDP port. However SNS tests require multiple NSVCs over a single UDP port.
NS_Provider_IPL4 already supports multiple NSVCs for the NS_Emulation.
Extend the support in NS_Provider_IPL4 to also allow RAW_NS to use
multiple NSVCs.

Thew newly-introduced "endpoint" mode of NS_Provider_IPL4 allows us
to have multiple NS-VC within one endpoint. NS_CT takes care of
creating the NS_Provider_IPL4 components on-the-fly, and then
associating the per-NSVC components with it.
For the user nothing changes, other than that he can now configure
multiple NSVCs with identical local IP + port, which was not possible
before.

This adds a new, optional "endpoint" mode to the IPL4 provider,
where we remove the constraint of "one NSVC per provider", which
in turn is a pre-requirement for real IP-SNS support with full
mesh of NS-VCs.
This code doesn't introduce any users of this "endpoint" mode yet.

This is something we need to simulate more complex scenarios,
particularly in the context of frame relay.

We want to see useful identification for components in the log, and
hence must be giving every component a name at create() time.

This allows NS_Emulation to react to changes of the underlying
transport layer (e.g. Frame Relay Link/DLCI up).

NSConfiguration currently contains parameters relevant only for IP
based transport. Move IP/UDP parameters into a sub-structure in
anticipation of Frame Relay support.

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.
