When BCCH INFO is received via RSL message, the rest octet of the System
Information 1 message is parsed to get the position of the NCH. The
position is stored in the gsm_bts structure. If the position is not
present int the rest octet, the stored value is set to negative.

This way the data model in TS 12.21 (Figure 1) is followed, where
there's a BTS Site Manager containing one or more BTS. In our case we
only support 1 BTS (cell) so far.

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.

* we have to use modulo 51, not 50
* the check for FACCH/SCH has to be applied to to the fn % 51 result

The parameter bs_ag_blks_res, which is loaded into the BTS via the SI3
setting, defines how many of the CCCH blocks shall be used for AGCH. The
remaining CCCH blocks will then be available as PCH for paging.
Unfortunately there is no unit-test yet that verifies that all of the 8
different settings for bs_ag_blks_res.
- Separate the the decision logic that checks if a given fn is part of
an AGCH into a function to have it available in the unit-test.
- Add a test that checks all possible bs_ag_blks_res settings.

Completely drop bts_log_init(), call osmo_init_logging2() directly instead: all
callers of bts_log_init() passed NULL as category string, so all it ever did
was call osmo_init_logging(). The bts_log_info is already declared in the .h.
Here and there also define a proper talloc root context instead of using NULL.

gsm_bts_role_bts was introduced at a time when we still shared
gsm_data_shared.[ch] between BSC and BTS, and where we then subsequently
needed a BTS-private structure. Since that sharing was abandoned quite
some time ago, we can merge gsm_bts_role_bts into gsm_bts and do away
with the bts/btsb dualism in a lot of the code.

we changed the gsm_bts_alloc() function signature to include
a second argument (the BTS number). This broke omso-bts, and this
commit is intended to make it build again.

This patch extends paging_gen_msg() by adding an output parameter
is_empty that is true, if only a paging message with dummy entries
has been placed into buffer. This feature is then used by
bts_ccch_copy_msg() to insert an AGCH message if is_empty is true.

Issue the RfDeactivate.REQ before sending the MphClose.REQ. Ideally
we would issue MphClose.REQ after the RfDeactivate.CNF but this is
not possible right now.
The current approach makes the following warning of the DSP go away
on shutdown. This was tested with my E71 and an active silent-call
using a SDCCH.
DSP Warning:
[ERROR] : DeviceMng_ValidateL1Handle() => Invalid layer 1 handle
The unit test created and used the paging request in the same
second and was passing because of that. Add a second test with
a delay to force now to not be equal to the expiration time.
Check that adding a paging command works, check that it is expired
after the first call to paging_gen_msg. The test will be extended
to test the scheduling and selection of the various paging messages.
