The new vty option "rtp hr-format (rfc5993|ts101318)" selects the
RTP output format to be used for HR1 codec, consistently across
all models. The default is set to match legacy behavior: ts101318
on osmo-bts-{lc15,oc2g,sysmo} and rfc5993 on osmo-bts-trx.
On models where no legacy behavior is applicable, the default is
set to rfc5993 as a forward-looking measure - see OS#6036.

In all OsmoBTS models in FR and EFR speech modes, as the UL traffic
frame stream is passed from the PHY to l1sap and ultimately to RTP
output, all passed frames are checked for SID. The Boolean result
of this SID check is used in two ways:
* RFC 3551 instructs that the Marker bit in the RTP header SHOULD be
set in the first packet of a talkspurt after a period of silence
suppression. OsmoBTS implements this recommendation by setting
the Marker bit in the first RTP-transmitted non-SID UL packet
that was preceded by SID.
* In osmo-bts-trx only, this same SID check serves a second purpose:
handling of BFI conditions depends on whether or not the last received
good traffic frame was a SID. If a BFI condition is received after
a non-SID traffic frame, the ECU is invoked, and if this ECU fails
or when libosmocodec does not provide an ECU for the codec in use,
a special FR (EFR) BFI frame of 260 (244) zero bits is emitted.
Both the ECU call and the peculiar form of BFI are skipped when the
last received good traffic frame was a SID.
For both of the above purposes, in all BTS models, change the SID check
from osmo_{fr,efr}_check_sid() to osmo_{fr,efr}_is_any_sid(). The
effect of this change is that "what counts as a SID" for the just-listed
purposes changes from recognizing only perfectly uncorrupted SID frames
without any bit errors to recognizing all frames which the rules of
GSM 06.31 (FR) or 06.81 (EFR) classify as either valid or invalid SID.

Commit 32682c63f6 fixed EFR SID handling in osmo-bts-sysmo,
but that fix was never propagated into osmo-bts-{lc15,oc2g} versions,
which are essentially copies of osmo-bts-sysmo. Fix that oversight.

This way we have further control on how to handle the SetAttr meessages
received. For instance, NACK them if the NM object FSMs are not at the expected
correct state.
The originating msgs are now kept owned and freed by the OML layer
(oml.c), and the NM FSMs only uses them and create new OML msgb when
answering with ACK/NACK.

This default phase of the Codec Mode Indication in downlink direction is
called "odd", which is defined by starting with CMC in every 26
multiframe.
At call set-up, after every successful handover and after a channel mode
modify, the default phase (odd) shall be used in downlink direction.
During a call, the phase of Codec Mode Indication may be changed in
downlink by using a RATSCCH message.
As we don't implement RATSCCH, odd is always correct.

When we receive a SID_FIRST_P1 frame from the PHY (during AMR/HR DTXu),
we must generate a SID frame on the RTP side.
The existing code
* ignored that the Amr_SidFirstP1 PHYIF message actually contains the
RTP payload
* manually generated the same content using osmo_amr_rtp_enc()
* forgot to prefix that with the AMR CMR+TOC
* in the end, sent a completely broken (too short) AMR SID frame over RTP
Let's fix this by simply using the 7-byte RTP payload with CMR+TOC that
the PHY is providing to us.

So far, we've had LOGPLCHAN() and LOGPFN(). This resulted in a number
of log lines containing frame numbers *not* containing the lchan
context, which makes it difficult to deterine which of potentially many

Let's introduce LOGPLCFN() for a FN-extended version of LOGPLCHAN(),
and convert all callers that have the related context.

ph_tch_req() is a recursive function and conditionally calls itself at
the very bottom. The recursive call happens iff all of the following
conditions are met:
* DTXd is enabled,
* AMR codec is in use,
* DTX DL AMR FSM state is recursive.
The problem is that ph_tch_req() may pull sizeof(*lsap) from the given
msgb twice: during the initial and the recursive calls. The second
attempt to pull sizeof(*lsap) causes the process to abort, because
the remaining room is less than it's attempting to pull.
AFAICT, doing msgb_pull() is not really necessary, given that
l1sap_tch_rts_ind() thankfully does set msg->l2h before pushing
the lsap header in front of the actual frame.
Update osmo-bts-sysmo and its copy-pasted siblings, which are likely
affected too, except osmo-bts-octphy which does not do the recursion.

This way it can be changed together with operative/availability state,
and changes announced to the BSC if present.
This commit presents no real change in osmo-bts behavior, since the only
place where adm_state is passed different than -1 is in
st_op_disabled_notinstalled_on_enter(), which is actually never called
(yet) since it's the initial state and no other states transition later
to it.
However, this will change in the future once we support re-connecting to
a (possibly different) BSC, which means objects will need to be moved to
that state to restart the whole OML install procedure on the new BSC.

lower layer specific APIs require first to enable the TRX object
(GsmL1_PrimId_MphInitReq, which requires ARFCN received during Set
Radio Carrier Attributes) before enabling the per-TS structure.
Hence, OPSTART must happen in RCARRIER MO before OPSTART can be sent to
the Radio Channel MOs, otherwise the initialization of the TS objet will
fail and OPSTART for the RadioChannel MO will send back a NACK.
In order to avoid this, we need to keep the RadioChannel MO announced as
"Disabled Dependency" until RCARRIER is OPSTARTed.

In change [1] the new power control structures and default params
were introduced. In change [2], the existing VTY commands for MS
power control in the BTS were deprecated and changed to use the
new structures as storage. Finally, in change [3], handling of
the power control parameters on the A-bis/RSL was implemented.
This change is the final logical step in the mentioned chain: it
makes both MS/BS power control loops use the new parameters, and
removes the old structures. The actual implementation of both
power control loops remains the same, however the expected output
of some unit tests for the Downlink loop needs to be changed:
- TC_fixed_mode: disabling dynamic power control becomes a separate
step of the test script since the field 'fixed' is removed;
- TC_rxlev_target: RxLev thresholds are printed 'as-is'.
Not all of the new parameters are used by the power control loops
yet. Further improvements to be done in the follow up commits.
