These two messages indicate that no ACK/NACK message is going to be
sent to the BSC because activation/deactivation was requested by the
PCU. This is absolutely normal and requires no attention from the
user/operator, so better use LOGL_INFO.

Parse the RTP CSD Format and reply with NACK if the mode is not
RSL_IPAC_RTP_CSD_TRAU_BTS, which is the only one we plan to implement
for now.

osmo-pcu requires to get DATA.ind for all FN/TS it manages in order to
tick its internal FN clock and trigger timeouts. Without this, some
events are ticked in a delay fashion when osmo-pcu detects FN jumps.

The variable rc holds the return code of accept(), which returns a file
descriptor on success. So lets call the variable "fd" to make this
clear.

A request to send an Immediate Assignment over the PCH (not AGCH)

Fix condition `block_nr == 4`, which was never reached, by effectively
replacing
- `4` by `msg->num_segs`, so we truly check if the current
block is the last of this message
- the index `block_nr` (which starts at zero) by `block_nr + 1`,
so it is comparable to `msg->num_segs`

The VTY command is "local-port", but write-config would write "port"
instead, which would fail when re-reading the config file.

Both power_ramp_start() and power_ramp_force() are now small macros
around _power_ramp_start()
The new behavior is:
* ramp down power when stopping bts through Ctrl-C
* the other shutdown causes skip power ramping
This will cause the bts to reconnect faster when the oml link is
dropped and power ramping is enabled.

There is no reason why they should have different initial
states. Keep it consistent with the other MOs.

This reverts commit c96d34f828.
Reason for revert: This breaks ramping up power since the power ramp logic still assumes the output is full power.

For the other shutdown causes power ramping doesn't make sense. Instead
shutdown quickly so we can reconnect faster

The pointer variable l1sap is only used to determine the size of the
related struct but for nothing else. We can use the struct name in
sizeof also directly and get rid of it.

Before this patch, the free CID with the smallest number was always
selected to be used. This caused more or less the same subset of CIDs to
be used all the time, while the CIDs with bigger numbers were mostly
unused.
Let's distribute the use so that all CIDs are used roughly the same.
This has the advantage, among others, that the same CID will not be
re-used immediatelly after being freed if a new call is established.
It is useful to leave the CIDs unused for some time since the other end
peer may know of the call being tear down with some delay.
Hence if a new call is established immediately after the CID was
released, the same CID would be allocated and passed at the peer, which
would then detect that the old call (in its view still active) would
already make use of that remote CID.

Lchans which are marked as non-connected have not yet received
information about its remote peer, hence they may not have some fields
available yet. Let's skip them to avoid accessing such fields
(lchan->abis_ip.osmux.in).

This is actually quite common, since our peer may be sending some osmux
packets to us a while after we have closed the conn on our side,
specially if latency is high in the network (eg satellite links).

This way we have no more access to internal osmux structures.
If those counters are needed in the future they can be counted by
osmo-bts by means of adding rate counters to the caller of
osmux_xfrm_input() and deliver_cb.

Otherwise some shared variables used by both Osmux and RTP was left set,
like connect_ip and connect_port, and next time the lchan was selected,
those were already configured even if they didn't come in IPAC CRCX.
This is specially bad if the channel was reused to set up an Osmux call,
since the osmux code path relied on those fields being properly reset
until set by IPAC CRCX.

when something fails in osmo-bts during startup and it goes into SHUTDOWN state,
it is desirable to close new RSL links (sockets) which are in progress to connect,
while it waits for a while to complete shutdown (power ramping down, etc.).
This way we don't end up with new interactions and new state against a BSC if we
are shutting down.
The new libosmo-abis API is used since the higher layer struct e1inp_sign_link assigned
to each struct gsm_bts_trx is not provided to the osmo-bts code layer by libosmo-abis API
until the TCP+IPA handshake in the socket becomes fully established (sign_link_up()
callback).

The function is long/complex enough, so having one extra struct in_addr
declared the function top only used in one specific small path to print
the variable is unnecesary.
Let's move it to the conditional path where it is used to print the
ip address.
