As the comment above the fix suggest, the encoding is in 10ms units.
osmo-bts is also doing the proper:
"""
uint8_t t3105 = *TLVP_VAL(&tp, NM_ATT_BTS_AIR_TIMER);
bts->t3105_ms = t3105 * 10;
"""

The VTY defun already indicates BSC_VTY_ATTR_RESTART_ABIS_OML_LINK
correctly, but so far we would immediately start using the new values
internally, and wrongly interpret interference levels. Fix that.
Have bts->interf_meas_params twice: interf_meas_params_cfg for the VTY
configured values, and interf_meas_params_used for the values that the
BTS actually knows about, after they were sent via OML.
In a running BSC, when changing the interference level boundaries on the
telnet VTY, the BTS is not immediately told about the change. That would
require a BTS restart. Hence store the cfg values separately in
interf_meas_params_cfg. For comparing/printing interference levels in a
running BTS, only employ the values that were actually sent via OML and
placed in interf_meas_params_used.

According to 3GPP TS 45.008, the BSS shall monitor the levels of
interference on its IDLE traffic channels. The actual measurements
are performed in the BTS and then reported to the BSC over the
A-bis/RSL link(s) in RF RESource INDication messages.
3GPP TS 45.008 defines the following measurement parameters:
* Intave: Interference Averaging period (see table A.1),
* Interference level Boundaries (see table A.1).
Both parameters are sent to the BTS over the A-bis/OML, and can
now be configured via the VTY interface. Only those BTS models
which 'speak' the OML protocol defined in 3GPP TS 52.021 will
actually get the configured parameters, others will keep using
the hard-coded parameters.

The only real 1-1 relationship between BTS NM objects is the one between
GPRS Cell and BTS (which is actually a BTS cell).
In our current osmo-bts implementation we don't care much since we only
handle 1-cell BTSses, but let's make the data structure organization
more generic.
Implementation notes:
The gsm_bts_sm is moved to its own file, APIs to allocate are added and
the new public object is hooked correctly in the allocation process of
osmo-bsc.

The old IE NM_ATT_IPACC_NS_LINK_CFG didn't support IPv6 NSVC.

Place all code related to the object into the related file.
Having all the data model in one file made sense in early stage of
development to make progress quickly, but nowadays it hurts more than
helps, due to constantly growing size and more and more bits being
added to the model, gaining in complexity.
Currently, having lots of different objects mixed up in gsm_data.h is a hole
of despair, where nobody can make any sense were to properly put new stuff
in, ending up with functions related to same object in different files
or with wrong prefixes, declarations of non-existing functions, etc.
because people cannot make up their mind on strict relation to objects
in the data model.
Splitting them in files really helps finding code operating on a
specific object and helping with logically splitting in the future.

Add a new VTY command "ccch load-indication-threshold <0-100>"
by which the user can configure the threshold after which the BTS
shall send CCCH LOAD IND. It used to be hard-coded to a
default value of 10.

Move the T_defs API to libosmocore as osmo_tdefs: remove the local T_defs API
and use libosmocore's osmo_tdef* API instead.
The root reason is moving the mgw_endpoint_fsm to libosmo-mgcp-client to be
able to use it in osmo-msc for inter-MSC handover.
When adding osmo_tdef, the new concept of timer groups was added to the API. It
would make sense to apply group names here as well, but do not modify the VTY
configuration for timers. The future might bring separate groups (or not).

This slightly simplifies things by making endianness more obvious and
removing abstraction.

Move all of libbsc/ into osmo-bsc/, and separate/move some implementations to
allow linking from utils/* and ipaccess/* without pulling in unccessary
dependencies.
Some utilities use gsm_network and gsm_bts structs, which already include data
structures for fairly advanced uses. Move initialization that only osmo-bsc
needs into new bsc_network_init() and bsc_bts_alloc_register() functions, so
that the leaner tools can use the old gsm_* versions without the need to link
everything (e.g. handover and lchan alloc code).
In some instances, there need to be stubs if to cut off linking "just before
the RSL level" and prevent dependencies from creeping in.
- abis_rsl_rcvmsg(): the only program currently interpreting RSL messages is
osmo-bsc, the utils are merely concerned with OML, if at all.
- paging_flush_bts(): ip.access nanobts models call this when the RSL link is
dropped. Only osmo-bsc actually needs to do anything there.
- on_gsm_ts_init(): the mechanism to trigger timeslot initialization is related
to OML, while this action to take on init would pull in RSL dependencies.
utils/ and ipaccess/ each have a stubs.c file to implement these stubs. Tests
implement stubs inline where required.
From src/utils/, src/ipaccess/ and tests/*/, link in .o files from osmo-bsc/.
In order for this to work, the osmo-bsc subdir must be built before the other
source trees. (An alternative would be to include the .c files as sources, but
that would re-compile them in every source tree. Not a large burden really, but
unless linking .o files gives problems, let's have the quicker build.)
Minor obvious cleanups creep in with this patch, I will not bother to name them
individually now unless code review asks me to.
Rationale:
1) libbsc has been separate to use it for osmo-nitb and osmo-bsc in the old
openbsc.git. This is no longer required, and spreading over libbsc and osmo-bsc
is distracting.
2) Recently, ridiculous linking requirements have made adding new functions
cumbersome, because libbsc has started depending on osmo-bsc/*.c
implementations: on gscon FSM and bssap functions. For example, neither
bs11_config nor ipaccess-config nor bts_test need handover_cfg or BSSMAP
message composition. It makes no sense to link the entire osmo-bsc to it, nor
do we want to keep adding stubs to each linking realm.
