Add a new common L1 SAPI enum, to unify all the BTS specific SAPIs.
Translate to this enum, and set the context for uplink messages in
each BTS specific implementation.
Set the context for downlink messages in the common l1sap code, by
converting the osmo_phsap_prim back to the SAPI value (mostly looking at
chan_nr). The new functions for doing this conversion,
get_common_sapi_by_trx_prim() and get_common_sapi_ph_data(), are based
on the existing to_gsmtap() and gsmtap_ph_data() functions.
Note that we can't set the uplink SAPI context in the common code,
because then we can't set it as early as possible. In this patch, the
SAPI context is set for the PHYs where the SAPI is readily available.
With additional conversion from the RSL channel, the SAPI context could
be set for osmo-bts-trx in a follow up patch.

Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its
parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However,
definition in C file doesn't contain "(void)", which means number of
parameters is undefined and thus compiler doesn't complain. Let's remove
parameters from all callers before enforcing "(void)" on it.
API osmo_stats_vty_add_cmds never had a param list but has seem problem
(no "void"), so some users decided to pass a parameter to it.

The radio link quality is defined by C/I (Carrier-to-Interference
ratio), which is computed from the training sequence of each
received burst, by comparing the "ideal" training sequence with
the actual (received) one.
Link quality measurements are used by L1SAP to filter out "ghost"
Access Bursts, and by the link quality adaptation algorithms. One
can define minimum link quality values using the VTY interface.
On the VTY interface we expect integer C/I values in centiBels
(cB, 10e-2 B), while the internal structures are using float
values in deciBels (dB, 10e-1 B). Some PHYs (sysmo, octphy,
oc2g, and litecell15) expose C/I measurements in deciBels,
while on the L1SAP interface we finally send then in centiBels.
Let's avoid this confusion and stick to a single format, that
will be used by the internal logic of OsmoBTS - integer values
(int16_t) in centiBels. This will give us the range of:
-32768 .. 32767 centiBels, or
-3276.8 .. 3276.7 deciBels,
which is certainly sufficient.

It looks like the status LED on the sysmobts2100 never worked correctly
since lc15bts-mgr expects osmo-bts-lc15 to create and manage
/var/run/osmo-bts/state, but there is nothing to do so in osmo-bts.
This patch copies the functions from oc2g to manage the state file in
lc15.

This commit doesn't change internal logic of any model, only the API to
be able to return result of connect TS asyncrhonously since some models
(like osmo-bts-trx) require some time to process the result. This way
PDCH ACT/DEACT (N)ACK can be sent once the result of this long process
is known. For instance, nowadays in osmo-bts-trx we PDCH (DE)ACT ACK
before getting the result from SETSLOT on the TRX iface.
With this new API, bts_model_ts_connect doesn't return any value
synchronously. Instead, it is expected to always end up calling
cb_ts_connected with the return code from the TS activation process. 0
is considered a successs, while any other value is considered an error.

No need to pass -t num_trx anymore to specify number of TRX to use. It
is calculated based on dynamic allocation from VTY config.
Using parameter -t is flagged as deprecated and is transformed into a
NOOP por backward compatibility.
As a result, TRX now are allocated after the BTS is allocated and
initial config (pre-VTY) is applied.
A new function bts_trx_init() is added, to set default config on each
TRX during allocation and before setting VTY config on it.
A new per BTS model function bts_model_trx_init() is added, to allow
per model specific default configuration of each TRX.

The existing implementation used a simplistic macro, which was wrong
in many ways:
1) it returned a negative value for "fn % 51 < 5" conditions without
raising any error message or asserting
2) it returned a wrong block number for many different input frame
numbers, as it didn't account properly for the FCCH/SCH gaps between
the blocks
Let's replace the simplistic macro with a proper lookup table based on
TS 05.02, and let's OSMO_ASSERT() if this is ever called with non-CCCH
frame numbers.

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.

Commit c2b4c668f3
I3b989580cb38082e3fd8fc50a11fedda13991092 introduces evaluation of ra_ind
members below the msgb_trim() call that actually invalidates ra_ind.
A symptom is that it breaks detection of Handover RACH, wich always ends up
with lchan == NULL and interpreting all RACH as chan_nr == 0x88.
Fix: do all evaluation of ra_ind before the msgb_trim(), for osmo-bts-sysmo,
litecell-15 and octphy.
To guard against similar mistakes in the future, set ra_ind = NULL before the
msgb_trim() call.

Before this patch we had:
* osmo-bts-trx internally using 1/256th bit/symbol period
* osmo-bts-sysmo internally using 1/4 bit/smbol period
* PCU interface using 1/4
* L1SAP interface using 1/4
* measurement processing code on top of L1SAP using 1/256
So for sysmo/lc15/octphy we are not loosing resolution, but for
osmo-bts-trx we're arbitrarily reducing the resolution via L1SAP
only then to compute with higher resolution again.
Let's change L1SAP to use 1/256 bits and hence not loose any resolution.
This requires a corresponding change in libosmocore for l1sap.h, which
is found in Change-Id Ibb58113c2819fe2d6d23ecbcfb8b3fce4055025d

In the past, rach_busy counting was performed below L1SAP, while
reporting was handled above. This lead to subtle differences between

Combined CCCH with CBCH is a separate PCHAN type and hence we must

impossible to use.

L1SAP uses 'ber10k' values, i.e. BER in 1/10000 units, where 10000
is all errors are bit-errors (= 100%).
The PHY on osmo-bts-sysmo and osmo-bts-lc15 is reporting a float fBer
value scaled to 1, i.e. 1.00 = 100% and hence must be 10000 as ber10k.
Before this patch, BER values reported on those BTS models were too
low by a factor of 100, resulting in way too optimistic RxQual values
reported to the BSC.
