I did not realize with my previous patch that there's a common place
where features available for all backends should be enabled. So move it
there.

According to osmo-bsc I0e80ca5afc06737273b6699bde6e325e454b57f6, the
PAGING_COORDINATION feature should be well supported in osmo-bts. Adjust
the bts_model_init functions to report this to the BSC, so it properly
sets this in SI13 and so we can avoid this notice in the log:
Get Attributes Response: reported feature 'PAGING_COORDINATION' is not supported, while we thought it is.

This will allow in the future advertising children objects that the
parent object has been configured. It is useful for instance to let TRX
know that the BTS is configured.

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.

New channel mode values have recently been added with change [1]
to 'enum gsm48_chan_mode'. The lack of default branch in
lchan2lch_par() caused build failures on Jenkins:
oml.c:956:2: error: enumeration value ‘GSM48_CMODE_SPEECH_V2_VAMOS’
not handled in switch [-Werror=switch]

This function is duplicated in osmo-bts-{lc15,oc2g,octphy,sysmo},
so we unfortunately need to apply the same fix to all copy-pasted files.

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.

Previous code relied on abort() switching sigaction to SIG_FDL +
retriggering SIGABRT in case the signal handler returns, which would
then generate the coredump + terminate the process.
However, if a SIGABRT is received from somewhere else (kill -SIGABRT),
then the process would print the talloc report and continue running,
which is not desired.

Similar to bts_vty_init(), BTS specific bts_model_vty_init()
requires a pointer to 'struct gsm_bts'. Not only it's used
as a parent talloc context, but also stored locally, so then
it can be used by some VTY commands.
Let's expose the global 'struct gsm_bts' from main, and pass
the application's talloc context like was done in [1].
This finally makes the BTS model specific options appear in
the automatically generated VTY reference (--vty-ref-xml).

All the Operative State logic to manage a RadioCarrier//BBTransc NM objects is
centralized in these FSM, where other parts of the code simply send
events to it.
This allows keeping state consistent and offloading logic from each bts
backend, since they are only required to submit events now.
The idea in the long run is to also replace other NM objects with
similar FSMs.
This improved logic fixes bug where PHY + RSL link became available before
OPSTART and hence op state changed to Enabled before receiving any OPSTART message.

This fixes old behavior mimicing broken behavior in nanoBTS (according to TS 12.21)
where BTS Site Mgr NM object was announced as Enabled despite no OPSTART
was sent by the BSC.
With this new FSM, BTS SiteManager will be announced as Disabled Offline
during OML startup conversation, instead of Enabled.
The new osmo-bsc OML management FSMs use this change in behavior to find
out whether it should use the old broken management states (without
Offline state, as per nanoBTS) or use the new state transitions (which
allow fixing several race conditions).
Change-Id: Iab2d17c45c9642860cd2d5d523c1baae24502243
This fix allows osmo-bts to play fine with newer osmo-bsc NM OML FSMs,
which expectes for non-nanoBTS types to follow TS 12.21 guidelines.
Until now, BSC simply waited to received State Event Change Dependency
for each TS and then sent all required commands (Set Chan Attr, Adm
Unlock and Opstart). In newer osmo-bsc FSMs, Opstart is only sent when
in Offline state, so we need to transit to that state. For the above
mentioned reason, since we pass through the Dependency state anyway
after this patch, older osmo-bscs will work correctly too.

We originally wanted to intrdouce an OML router which would permit
external proceses to implement certain OML MOs. However, that code
was never completed, and all the existing implementation (in three
copies) does is to create a unix domain socket and discard what
is received there.

Some backends like osmo-bts-trx require exchanging messages like
POWEROFF to close the TRX, and hence need some time. Switch the function
to expect result asynchronously by calling a callback.
This will be used later to wait until all TRX are really powered off
before exiting the process.

It was a very bad idea to mix "public" BTS features, that are
reported to the BSC via OML, and those features, that are used
locally (and exclusively) in osmo-bts.
Why? At least because we already have the BTS feature manipulation
API in libosmocore, that is used by osmo-bsc, but for some reason
not by osmo-bts. New features added to libosmocore would clash
with the existing "internal" ones like BTS_FEAT_MS_PWR_CTRL_DSP.
So what this change does can be described as follows:
- remove duplicate definition of the "public" features,
- use libosmocore's API for the "public" features,
- separate both "internal" and "public" features:
- the "public" features continue to live in bitvec,
- the "internal" features become flags,
- s/BTS_FEAT/BTS_INTERNAL_FLAG/g.
Change-Id: Icf792d02323bb73e3b8d46384c7890cb1eb4731e
New define is available since libosmocore 1.1.0, and we already require
1.3.0, so no need to update dependenices.
Let's change it to avoid people re-using old BSC_FD_READ symbol when
copy-pasting somewhere else.

The struct members ber10k, ta_offs_256bits and lqual_cb in ph_data_ind
are only populated when the pcu_direct flag is not set.
The pcu_direct flag is set when the pcu is directly attached to the phy
and all pcu related traffic (pdtch) is handled without sending it through
osmo-bts-sysmo. For those cases osmo_bts_sysmo will not make use of
those struct members, even if they were populated. When the PCU is not
directly attached the data is needed because it is sent through the
pcu_sock to the PCU.
Lets remove the check because it is not required. Also in future patches
where measurement indications and data / tch indicatins are merged the
struct members are also needed to carry the measurement information for
SACCH as well.

It indicates whether BTS model supports managing an MS Power Control
Loop over HW/DSP instead of using the software based osmocom algorithm
present in osmo-bts.
osmo-bts-trx own loop implementation is considered to be a "DSP/HW" one
since it acts on lower layers and interferes with osmocom algorithm
since it controls the same end variable "lchan->ms_power_ctrl.current",
this way we make sure both aren't enabled at the same time.
Old behavior in kept: if common upper-layer algo is not enabled
explicitly in VTY (ms-power-control osmo) and bts-trx specific lower
layer algo is neither enabled (osmotrx ms-power-loop <xyz>), then no
power control is done at all.
