Let's keep some statistics about the min/max/average frame number
advance that we're observing above L1SAP when comparing the time in the
PH-RTS.ind and the frame number we observe in PH-DATA.ind of data
that was received on the uplink.
The statistics are currently only shown in the VTY, but this is a
precursor to using them to correctly advance the LAPDm timers in a
follow-up patch.

This adds the final missing part to full CBCH support:
* keep a tab on the current queue length for basic + extended CBCH
* keep rate counters about the number of sent / transmitted SMSCB
* send CBCH LOAD information via RSL to the BSC

The logic for Extended CBCH are the same as for the Basic CBCH, we just
need to
* duplicate our related state
* parse the optional RSL_IE_SMSCB_CHAN_INDICATOR IE
* start to send data on the Extended CBCH (TB=4..7)

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.

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 current implementation does not allow the user to specify a port
range in which the BTS is allowed to allocate a local RTP port. Also
the ports the BTS picks do not match the policy described in RFC3550.
An RTP Port must be at an even port number and the matching RTCP
port must be at the following (odd) port number. The BTS currently
picks random port numbers for both.
- Add a VTY command to specify a port range in which the BTS may
assign local ports.
- Pick ports as described in RFC3550.

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.

Normal Abis RSL MEasurement Results contain only the "MS Timing Offset
IE" in units of full symbols. In some use cases it is important to have
higher-accuracy timing information exposed to the BSC.
We do this by adding the average timing offset value during the last
measurement interval in 1/256th symbol accuracy to the "Supplementary
MEasuremen Information" part of the TS 48.058 9.3.25 Uplink Measurements
IE.
In order to avoid any compatibility issues, this feature is only enabled
if the new vty config command "supp-meas-info toa256" at the bts node
is enabled.

When decoding RACH bursts, we should use a BER threshold in order to
help distinguish 'ghost' RACH bursts from real RACH bursts.
The theoretical ideal threshold according to some papers is 7 out of 41
bits qhich aquals to Eb/N0 of 0 dB = 0.1707 (17.07%)
We add a new 'ber10k' parameter to the RACH indication l1sap primitive
(needs separate change for libosmocore), and then fill this value from
osmo-bts-{sysmo,lc15,trx,octphy}. The common part above L1SAP then
applies the threshold, which can be changed from vty using the
"max-ber10k-rach <0-10000>"
command available at the BTS node. The unit is BER in 1/10000, i.e. a
value of 100 equals 1% bit error rate.

OsmoBTS won't run without being connected to a BSC. The BTS wouldn't
start to transmit if the BSC doesn't properly initialize it. So if we
want to activate some channels manually for testing, we should do so
from the BSC, and not inside the BTS code. Doing this in the BTS means
that the BSC is not aware of it and might want to use that channel for
something else meanwhile.
Osmo{BSC,NITB} has gained ability to manually activate a channel from
the VTY in Change-Id I44fc3904678eb48bd3ab1a3da8c0c265fa082e0d as can be
seen at https://gerrit.osmocom.org/2759
So let's remove the old/obsoleted code here.

Making use of the multi-trx feature requires to tell osmo-bts that
more than one transceiver are available. Otherwise it will complain
that not enough transceivers are available. This can be quite
confusing, even a correct config file will fail to parse if it
specifies more transcrivers than available.
This patch adds a hint to the error message so that the user knows
that he should check the -t commandline option

The vty write for phy/inst is broken, leading to a written-out config being
unparsable; fix all of these:
- in common/vty.c, actually call bts_model_config_write_phy_inst().
- in sysmo and lc15 write the phy instance elements in
bts_model_config_write_phy_inst() and not in bts_model_config_write_phy(),
which lead to writing the members above their parent 'instance'.
- sysmo, lc15 and oct omit the bts_model_config_write_phy_inst()
implementation. This did not cause a compilation problem because it
was in fact never called.
- sysmo writes 'clock-source None' when clk_src is zero, leading to unparsable
config (related: OS#1944). Instead omit the 'clock-source' when zero.
- osmo-bts-trx seems to be the only part that lacks nothing, yet it
also didn't work properly because bts_model_config_write_phy_inst()
was never called.
This problem existed since commit d784e50747

OsmoBTS# configure terminal
OsmoBTS(config)# bts 0

This is the easiest way I found to make BTS level loopback to work.
Another way to implement this is to have BSC/NITB to send the OML command, but
it's a longer path with no clear benefits.
Note, that the current code hardcodes the channel to be TCH/F with v1 speech,
which is what we need for the basic BER testing. We may want to extend this
later to support more channel types.

In some cases we'd like to run multiple instances of osmo-bts on a
single machine. This is the case where we a multi-TRX PHY is to be used
for several BTSs, or in case osmo-bts-trx has multple SDRs attached.
This wa currently prevented by having a hard-coded PCU socket path
and telnet port, which are now configurable via VTY / config file
itself.
It remains up to the individual BTS hardware models to decide
whether or not to register those commands (depending on whether they
support the feature) via cfg_bts_auto_band_cmd / cfg_bts_no_auto_band_cmd
At the time the phy link / phy instance level VTY configuration
commands are parsed, we did not yet call l1if_open() and thus
pinst->u.{lc15,sysmobts}.hdl == NULL.
PHY or PHY instance specific configuration must thus be stored inside
the phy_link or phy_instance itself, and not inside the (not yet
existing) handle.
We solve this by moving around some parameters:
* clk_use_eeprom/clk_cal/clk_src/calib_path get replicated in
phy_instance
* min_qual_{rach,norm} are moved into the generic part (which means
that osmo-bts-octphy and osmo-bts-trx should also implement them)
Instead of limiting the number of TRX at VTY to the actual number of
supported TRX, VTY allows to configure any possible number of TRX. If a
TRX is configured, which is not supported by BTS model, an error message is
returned, which states that the given TRX is not supported.
MS uplink power control is required in pretty much any BTS, and we
cannot assume that they PHY / L1 will always take care of it by
itself. So the correspondign code is moved to common/power_control.c
and called from the generic part of L1SAP.
The corresponding VTY paramter has been moved from the sysmobts-specific
trx VTY node to the common BTS VTY node.
