This fixes a bug introduced more than one year ago in commit
e38bd6caa34005816a9336f021fd17d328d5c901:
The RSL_IE_CHAN_IDENT is a TLV, but the GSM48_IE_CHANDESC_2 contained in
it, is a mere TV type IE with fixed length.
The problem specifically has caused problems on Nokia MetroSite BTS,
which apparently read the TSC out of this Layer3 IE.
Reset the BTS MO State on BTS bootstrap. This way we will always
test the BTS disconnect/reconnect case of the BTS.
Do not reset the administrative state of objects. The BSC might
have set these and wants to maintain them across disconnect/
reconnect. Right now this is true for the TRX state.
The daemons set up nanoBTS and HSL femto sockets by default, ie. the
three sockets to support these two drivers are open even if we have
no BTS of that kind.
This patch enables on-demand socket creation, ie. we only enable them
if we have one BTS at least that requires it.
I added two new attributes to the gsm_bts object, they are:
* the start() function includes the code that we need to run to start
the BTS. This new function contains the socket creation in the
particular case of nanoBTS and HSL femto.
* the started boolean, which is used to know if we have already
started the BTS, ie. we have already invoked start().
Note that, I have splitted the bts_model_*_init() function into two
functions, the _init() functions that register the BTS driver
and the _start() functions that start BTS driver on-demand.
While I was at it, I added several changes/cleanups to this patch:
* Group all bts_model_*_init() calls into one function bts_init(),
which is called in the initialization path of osmo-nitb and
osmo-bsc.
* Add openbsc/bss.h that contains the declaration of
bsc_bootstrap_network, bsc_shutdown_net and bts_init.
* Add missing e1inp_init() in osmo-bsc.
* Fix missing declaration of hsl_setup in openbsc/e1_input.h
The error message was missing in case of problems bootstrapping the BTS.
The E1 input driver initialization was displayed in the standard output,
now this error is reported via logs.
The code to create the struct gsm_bts is in libcommon right now
and we can not call paging_init from there. Right now it appears
to be the easiest of doing the init internally.
Be able to configure a list of destinations (duplicates allowed)
that will be tried in a round robin fashion. The change is in
the bsc_msc_connection to operate on a list. We achieve the
round robin nature with the same trick used in the paging code
to delete and append the current entry. The nat code was updated
to compile but one can only configure one destination.
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]

This change is required to finish the integration of the VTY and
the per-application logging categories that provides:
"vty: integration with logging framework"
in libosmocore.
It has been tested with osmo-nitb. The other just compiled tested.
This is the case of osmo-nitb, since it does not call
osmo_bsc_rf_create().
term1: $ ./osmo-nitb -c ../openbsc.cfg.nanobts
