It's not a good idea to request big changes in MS Power based on
sporadic bad signal received, let's instead change announced MS power
levels more smoothly to avoid possible big signal strength fluctations,
similar to what is already done in osmo-bts-trx specific loop (loops.c).

Thies field is used to store and retrieve whether MS power needs to be
calculated and updated by osmo-bts software or autonomously by lower
layers. Previous name was not clear
and may have been understood as indicating whether MS Power Control loop
is done or not in general, and the responsible for that is located under

The ETWS (Earthquake and Tsunami Warning System) uses a so-called
ETWS Primary Notification which is sent
* to phones in dedicated mode (via DCCH from the BSC)
* to phones in idle mode (via P1 Rest Octets on PCH/CCCH)
This patch implements the second part of the functionality, i.e.
transmitting the related ETWS Primary Notification via PCH. As
3GPP doesn't specify how this is communicated over Abis, we use
a new, vendor-specific RSL message type.

This commit doesn't change internal logic of any model, only the API to
be able to return result of connect TS asyncrhonously since some models
(like osmo-bts-trx) require some time to process the result. This way
PDCH ACT/DEACT (N)ACK can be sent once the result of this long process
is known. For instance, nowadays in osmo-bts-trx we PDCH (DE)ACT ACK
before getting the result from SETSLOT on the TRX iface.
With this new API, bts_model_ts_connect doesn't return any value
synchronously. Instead, it is expected to always end up calling
cb_ts_connected with the return code from the TS activation process. 0
is considered a successs, while any other value is considered an error.

No need to pass -t num_trx anymore to specify number of TRX to use. It
is calculated based on dynamic allocation from VTY config.
Using parameter -t is flagged as deprecated and is transformed into a
NOOP por backward compatibility.
As a result, TRX now are allocated after the BTS is allocated and
initial config (pre-VTY) is applied.
A new function bts_trx_init() is added, to set default config on each
TRX during allocation and before setting VTY config on it.
A new per BTS model function bts_model_trx_init() is added, to allow
per model specific default configuration of each TRX.

The function is_meas_overdue() was introduced to allow
lchan_meas_process_measurement() to detect when the end of a measurement
interval has been missed. Interval ends may be missed when the SACCH
block of the related measurement interval gets lost. This is due to the
fact that the SACCH block is used as a trigger to start the measurement
result computation.
The idea behind is_meas_overdue() was to check the frame number of the
current measurement against the frame number of the previous measurement
in order to see if there was a measurement for SACCH in between or not.
Unfortunately SACCH and TCH Voice data is not necessarly processed in
order by each phy. Depending on the phy there may be a jitter between
the timing of SACCH and TCH Voice. Depending on the phy this jitter may
be enough to mess up the timing so that we see a SACCH block earlier
than expected. So we can not use the current frame number of TCH Voice
measurements to check for missed SACCH blocks.

The parameter bs_ag_blks_res, which is loaded into the BTS via the SI3

At the moment the measurement calculation of osmo-bts works by
collecting the measurement reports the phy emits during a measurement
interval. Normally one would expect a well defind fixed number here, but
some phys will not emit a measurement report for lost blocks. Also
blocks and their reports may get lost because of cpu overload etc.
The computation that is executed at the end of the measurement interval
computes over all received measurement. This evenutally means that
missing measurements will not taken into account and the result will
look better than it is in reality.
To fix this, the interval must be of a defined size and in cases where
less measurements as expected were collected, the algorithm must assume
they have been received with a 100%BER and take that into account.
However, all RSSI and TA/TOA related computations should continue to
rely on actual measurement data.
- make sure the algorithm works over a fixed interval
- replace missing measurements with 100%BER
- fix and extend unit-tests

the measurement interval end is detected by using the measurement
indication that is related to the SACCH block as a trigger to start the
computation. If the measurement indication for the SACCH gets lost
because the block could not be received then the processing is not
executed. This may cause wrong results or when it happens condecutively
an overflow of the measurement sample buffer.
- Store the frame number of the last received measurement indication
- Use the stored frame number to check if an interval was crossed when
the next measurement indication is received. If we detect that we
missed the interval, catch up by running the computation and
start the next interval.

We saw in a recent prod setup a BSC with saturated channels. Further
investigation lead to a AGCH queue of 1000 (previous hard_limit)
messages, most of them being regular IMM ASSIGN (non REJ). Hence, we
also want to get rid of other messages in the AGCH queue (like regular
IMM ASSIGN).
Furthermore, In this scenario, sending IMM ASS REJ is as important as other
messages given than nowadays we support dynamic wait indicatior
(calculated based on chan load), which means if we reach the MS, we can
tell it to wait for a long time to reach us again, which is desirable.

In a prod setup, complete channel saturation at the bsc was detected,
and Immediate Assignments were not being answered by the MS once sent by
the BTS.
Further investigation showed that the BTS was all the time printing
messages like this:
"bts.c:540 AGCH: too many messages in queue, refusing message type 0x3f, length = 1001/10"
So it seems the AGCH queue was becoming incredibly full (1000, hard
limit triggered the log), while acgch_queue.max_length was set to 10.
As a result, most probably the Immediate Assignments being sent to the
MS are super old in time, and the MS doesn't known about them anymore
once they are receivied, so no answer is sent back.
Let's try to avoid that by decreasing the hard limit so we never reach
that big queue_len scenario.
The number 100 is selected from data gatherered in agch_test.c which
prints a table of max_length values based on different setups. Some
values can reach around 80 messages, so let's use a slightly bigger hard
limit.

osmo-bts has a table of pchan/channel mode combinations for every

The end of the measurement reporting period is not aligned with the
SACCH block where the results are reported. The tables that are
used to detect the end of the measurement period are therefore
wrong. The frame number of the SACCH block must be used and not the
TDMA frame number (modulo 104) of the measurement reporing interval.
The tables are oriented to the frame number of the first SACCH block,
at the beginning of an interval. However, when a SACCH block is received
it will always contain the result of the recently passed measurement
reporting period.
To match the tables, introduce another lookup table to remap each
SACCH block that ends to the matching beginning block number.
