I'd like you to reexamine a change. Please visit

https://gerrit.osmocom.org/c/osmo-bsc/+/16352

to look at the new patch set (#4).

fix inp_sig_cb(): dispatch TS_EV_OML_DOWN to all transceivers

When running a multi-trx setup, upon stopping osmo-bts one can see:

DCHAN ERROR lchan_fsm.c:80 lchan(0-1-7-TCH_F-0)[0x612000010120]{UNUSED}: (type=NONE) lchan allocation failed in state UNUSED: LCHAN_EV_TS_ERROR DCHAN ERROR lchan_fsm.c:144 lchan(0-1-7-TCH_F-0)[0x612000010120]{UNUSED}: (type=NONE) lchan activation failed (lchan allocation failed in state UNUSED: LCHAN_EV_TS_ERROR)

These messages show up when the following conditions are met:

* BTS model speaks A-bis over IP (ip.access, e.g. nanoBTS), and * BTS has more than one transceiver configured.

The problem is that unlike traditional E1 based BTS models, ip.access ones have a single global A-bis/OML link for all transceivers. Thus when it goes down, in inp_sig_cb() we need to notify all timeslots *of all TRXes*, not just TRX0.
