Allow configuring MGW conns with multiple codecs. The new codecs filter
can have multiple results, and MGCP can configure multiple codecs. Get
rid of this bottleneck in-between that so far limits to a single codec.
Many members, arguments and logging say "codec", which should
accurately now say "codecs" (plural). Postpone such renaming to a
separate patch, to better show actual functional changes here.

Codec List (BSS Supported) is received once in Complete Layer 3 and
again in Assignment Complete messages. Use the most recent one, i.e. the
one from Assignment Complete, when it occurs.

I noticed by chance that the Assignment Complete message generated in
the test lacks a remote RTP address for the RAN side.
Make the test more realistic by adding a remote RTP address and port. It
doesn't have any bearing on the tests besides more accurately showing
RTP stream setup in the logs.

Use either the SDP or the Bearer Capabilites indicated in the incoming
MNCC to apply the remote call leg's codecs selection to the codecs
filter. Use the codecs filter result for outgoing Bearer Capabilites.
So far, we just forwarded the Bearer Capabilities received in MNCC from
the remote call leg, and omitted Bearer Cap if the remote call leg did
not provide any.
Instead, always include Bearer Cap, and compose it from the codecs
filter result. Hence the Bearer Cap is now an intersection of MS, BSS
and remote call leg, instead of just the remote call leg.

The initial Compl L3 happens long before we establish a CC transaction.

codecs filter with it. Subsequent patches implement feeding the filter.

Converting between different codec representations is confusing. This
codec mapping provides a consolidated overview of all our codec
representations, and how they match up.
In particular, it adds the SDP codec representation repertoire,
preparing the use of full SDP on the MNCC interface.

When the HLR fails to return auth info and authentication and ciphering
are configured to be optional, fall back to no-auth.
This patch concludes a series of preparatory patches and implements the
actual functional change.

Add third outcome of auth_fsm: the no_auth_info_event, which should be
dispatched when auth failed because the HLR has no auth info for this
subscriber, i.e. not because an actual auth challenge failed.
No functional change: Handling no_auth_info_event separately follows in
another patch (to allow fallback to no-auth). Feed the same
_E_AUTH_FAILURE as no_auth_info_event to still behave unchanged.

Explicitly send distinct parent events on auth success and failure. So
far determining success depended only on the data pointer passed on with
the event. Distinct events clarify the logging and the FSM code.
This prepares for a third FSM outcome to be added in a subsequent patch,
to separately signal when the HLR has no auth data.
No functional change.

For establishing Layer 3, pass a flag from msc_a to VLR that indicates
to fail if encryption is not possible.
An earlier patch [1] renamed a previously existing flag
require_ciphering to is_ciphering_to_be_attempted, because the naming
was not accurate. This new flag now indicates what its name suggests.
This new flag is needed for upcoming patch [2] to distinguish between
optional and mandatory encryption.

Clarify the name to avoid confusion in upcoming patches.
This function actually returns whether any ciphering mode besides A5/0
is enabled, and does not imply that ciphering is mandatory. A5/0 may
well be allowed when this function returns true.

Since call_leg_fsm_releasing_onenter() calls immediatelly
osmo_fsm_inst_term(), it meant we couldn't receive any event in that
state because osmo_fsm disables event dispatching to FSMs being
terminated.
As a result, CALL_LEG_EV_MGW_ENDPOINT_GONE was never received and hence
call_leg_mgw_endpoint_gone() was never called, which means the
mgcp_client used in cl->mgw_endpoint was never put back to the pool.
By first freeing all the children (rtp_streams), we make sure
cl->mgw_endpoint ends up with no conns and sends us the GONE event
before we go ourselves into termination state.

Let's use the new API available in libosmo-mgcp-client to control more
consciously where the mgw pool config is printed.

Large RAN installations may benefit from distributing the RTP voice
stream load over multiple media gateways.
libosmo-mgcp-client supports MGW pooling since version 1.8.0 (more than
one year ago). OsmoBSC has already been making use of it since then (see
osmo-bsc.git 8d22e6870637ed6d392a8a77aeaebc51b23a8a50); lets use this
feature in osmo-msc too.
This commit is also part of a series of patches cleaning up
libosmo-mgcp-client and slowly getting rid of the old non-mgw-pooled VTY
configuration, in order to keep only 1 way to configure
libosmo-mgcp-client through VTY.

Those commands are not controlled/implemented in this repository, so
it's a bad idea having them show up here, since they may change. be
modified, become deprecated, etc.
They are actually becoming deprecated now in libosmo-mgcp-client
(osmo-mgw.git Change-Id Id55af13d2ecde49d968b9dca6a2f8108a17ec484) and
hence they don't appear anymore when listing the node.

The timer "mgw X2" (RTP stream establishing timeout)
is set by default to 30 seconds.
When an MT call is ringing and remains unanswered, it
is this timer that will expire, and the call is terminated.
Up to now this results in a CC_CAUSE of Resource Unavailable
and if osmo-sip-connector is in use, the SIP agent will
get 503 Service Unavailable.
While "resource unavailable" may be technically correct, in
that the MGW did not return an rtp stream in time, returning
"No User Responding" (resulting in SIP 480) is probably a
more accurate description of what actually happened,
allowing the switch to inform the caller.
