libosmocodec has recently introduced a generic ECU abstraction layer
which supports (pluggable) Error Concealment Units for not only the
FR codec, but potentially any other codec, too.

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.

For some strange historical reason, the baseband transceiver MO was
brought up in state "UNLOCKED".
The object should come up in "locked" state until it's explicitly
unlocked by the BSC.
See Section 6.8.2 of TS 12.21: "If there is yet no administrative state
value explicitly set by the BSC (e.g., at an initialization time), the
object shall be presumed to be administratively locked by default"

When osmo-bts connects to the BSC, it sends a ton of "State Change Event
Report" messages indicating the Operational State (NULL), Availability
status (power off) and [as an osmocom extension] also the Administrative
State. However, the value of the administrative state is "0", which is
not defined in TS 12.21 Section 9.4.4

TRX0 is allocated in a different place than other TRX.
Commit that introduced the bug added an initialization step
(bts_trx_init) applied in VTY cmd "trx <0-254>", where TRX are allocated
since same commit, but doesn't initialize TRX0 for reasons explained in
first paragraph.
As a result, some parameters were not applied to TRX0, like
power ramping increment step, which prevented MS from finding the network in
osmo-gsm-tester tests.

Before this patch it was being coded as SDCCH4 TS0 SS 0, and as a
result the state LCHAN_REL_ACT_OML applied in opstart_compl in abused
SDCCH4 TS0 SS 4 was not being checked when deciding whether to send a
Chan Act ACK in rsl_tx_chan_act_acknack.
Fixes: OS#3513

Previous implementation made no sense, since chan_nr is never read
before being set below from lchan_nr.
Furthemore, if lcahn_nr=CCH_LCHAN=4, then:
cbits = 0x4 + lchan_nr = 0x8 = b1000 which then becomes SDCCH8 according
to GSM 08.58 9.3.1, so it's totally wrong:
SDCCH/8 + ACCH 0 1 T T T

To allow switching a dyn TS also between TCH/H <-> TCH/F and anything else,
don't thwart RSL messages just because their chan_nr doesn't reflect the
current pchan mode. For dyn TS, leave that to message handling.
In particular, a TS switch is invoked by a Chan Activ message, in which case
the current pchan by definition mismatches the incoming chan_nr's reflected
channel type.
With this patch, I have tested successful direct TCH/H<->TCH/F switchover on
sysmoBTS, with osmo-bsc patch I72d5d833b186b1e1925d513885b405d8c19aa496 (and
'msc'/'codec-list' vty config to change TCH kinds while gprs mode was none).

In gsm_lchan2chan_nr(), use a switch to reflect both dyn TS kinds and enrich
with comments. Move GSM_PCHAN_TCH_F_PDCH out of gsm_pchan2chan_nr(), which is
now back to pure standard PCHAN values.
Rationale: it's easier to figure out what is going on and why.

in change-id Iebd2571726d1284a7431b3f9b23ad3185e832ed1 we introduced
tighter validation on whether the requested channel number matches the
underlying physical channel configuration. Unfortunately this broke
activation of an osmocom-style dynamic PDCH as TCH/F or TCH/H
rsl_lchan_lookup already permitted a chan_nr if the dynamic PDCH was
already switched to the given TCH mode, or at least the related
switching had already been initiated.
However, in the case of the bug, the current type is NONE, which means
that the compatibility check of rsl_lchan_lookup will fail
Let's relax the checks of rsl_lchan_lookup() slightly to permit
matching for "ts->dyn.pchan_is == GSM_PCHAN_NONE" cases.
This fixes BTS_Tests.TC_dyn_osmo_pdch_tchh_act and
BTS_Tests.TC_dyn_osmo_pdch_tchf_act

This is used only in integration testing, where in the TTCN-3 testsuite
we currently have no A-bis OML implementation, but only a RSL one.

What we remove here is a legacy from sharing this header file with
openbsc/osmo-bsc-sccplite, which we stopped to do quite some time ago
and hence can remove those parts that are only relevant to the BSC but
not to the BTS.

This adds printing of remote RTP IP/Port, LAPDm SAPI information,
MS Timing offset, propagation delay, encryption algorithm+state,
loopback status and radio link failure counter to the "show lchan"
command. It also adds TODO comments fro those bits that are not yet
printed but which would make sense to print.

The RTCP Sender Description is supposed to contain useful information
to identify the source of the RTP stream. So far, it only contained
compile-time default data of libortp. Let's put the BTS UnitID, the
lchan number and the OsmoBTS version in there.

* copy-paste gsm_data_shared.* from OpenBSC master
* remove corresponding configure check and option
* remove .deb dependency
Actual refactoring with removal of unnecessary structures/parts, moving
common OpenBSC/OsmoBSC parts into libraries etc. are left for further
patches.
Current patch will make coexistence with *BSC easier and will simplify
our build infrastructure.

This code re-works osmo-bts to add support for the upcoming sysmocom BTS.
It also tries to add some level of abstraction between the generic
part of a BTS (A-bis, RSL, OML, data structures, paging scheduling,
BCCH/AGCH scheduling, etc.) and the actual hardware-specific bits.
The hardware-specific bits are currently only implemented for the sysmocom
femtobts, but should be (re-)added for osmocom-bb, as well as a virtual
BTS for simulation purpose later.
The sysmocom bts specific parts require hardware-specific header files
which are (at least currently) not publicly distributed.
