The out "RSSI" parameter is only filled by USRPDevice, and not used at
all by any user of the API (radioInterface*.cpp).
RSSI seems to be computed nowadays in the common path in
Transceiver::pullRadioVector().

With current state multi-arfcn can be used (eg. I can place a call
between 2 phones using TRX1 and sustain for as long as wanted), but from
time to time (around every 20seconds), a burst of Tx packed dropped
events from LimeSuite appears.
LimeNet-micro coefficients have yet not been tested.

Right now the values are the same for all devices, but they will differ
in forthcoming commits once multi-arfcn support is added.

Add an enum containing each supported device type (LimeSDR-USB,
LimeSDR-Mini and LimeNet-Micro) plus "unknown", to leave some room for
yet-to-come devices to run with some generic parameters without
rebuilding osmo-trx.
Each device type is assigned a dev_desc structure, and all of them are
put in HashMap, similar to what's already done in UHDDevice.cpp.
Device type is infered from string provided by LMS_GetDeviceInfo(), as
it was already done before in several places. From now on, we only need
to parse the string once since we store the device type after first
during open time.
Later on, more fields will be moved to device-type specific structure,
such as Tx timing offset, clock rate, etc.

Release is done in destructor, so let's move allocation to constructor
since there's really no need to have them in open() which is already
quite complex and large.

channel number mangling based on multi-arfcn feature being enabled was
moved to generic radioDevice() to reuse code. Hence, the generic parent
constructor sets this->chans to 1 if multi-arfcn feature is requested.
However, LMSDevice constructor argument had same name as the class
instance attribute, taking preference. As a result, if multi-arfcn is
enabled in LMSDevice, the generic constructor first sets this->chans=1
but afterwards LMSDEvice constructor keeps calling .resize() with the
argument value "chans" instead of using this->chans.
Let's rename the argument in all radioDevice child class constructors to
avoid potential future bugs in all of them.

Make sure old configs using "logging level lms <level>" are still accepted.
Initialization order of VTY componenets need to be resorted since newly

beforehand.

This way switch is applied correctly to parent structures and features
can be used later by other children classes (other devices).

After previous changes, radioInterfaceMulti is expected to handle channel
conversion correctly, so it will always use chan 0 for all these
functions. This simplifies code in radioDevice avoiding need to add
checks to all devices supporting multi-arfcn in the future.

This code is not needed anymore since we are setting SCHED_RR scheduler
with a real time priority in main thread during startup, so all threads
will inherit same rt priority, which should be enough to keep the
process working reliably even on high system loads (from non rt
processes).
osmo-trx was tested to be reliable during test with stress-ng as
explained in related ticket below.

rx_underrun events are not happening in general for any SDR (don't
exist), so let's drop that counter. Instead, add Tx Dropped Packet counters,
which were not accounted prior to this commit.

It was initially thought that underruns/overrun fields were
increasing-over-time values.
However, after reading LimeSuite code, it seems overrun and
underrun fields are actually reset upon every call to
LMS_GetStreamStatus().

Introduce a unified implementation-agnostic interface for radioDevice to
signal SDR error counters to upper layers and manage them.
This patch only implements counters for osmo-trx-lms (other devices will
show all counters unchanged during time).
Sample use through VTY:
"""
OsmoTRX> show rate-counters
osmo-trx statistics 0:
device:rx_underruns: 0 (0/s 0/m 0/h 0/d) Number of Rx underruns
device:rx_overruns: 0 (0/s 0/m 0/h 0/d) Number of Rx overruns
device:tx_underruns: 0 (0/s 0/m 0/h 0/d) Number of Tx underruns
device:rx_drop_events: 4 (0/s 2/m 3/h 0/d) Number of times Rx samples were dropped by HW
device:rx_drop_samples: 513 (0/s 196/m 425/h 0/d) Number of Rx samples dropped by HW
"""

Existing code had a typo (value was assigned from wrong variable).
Furthermore, it was experimentally found that:
while underrun/overrun are documented as "FIFO overrun
count" in LimeSuite.h, it seems droppedPackets ("Number of dropped
packets by HW") is not actually an incrementing counter like the others,
but simply a value set every time LMS_RecvStream() is called. Since we
are actually interested in keeping the count over time, adjust code to
achieve that.

Also take the chance to make sure we handle properly short reads (keep
reading again).
Both scenarios can be tested by running osmo-trx-lms and then using
on a terminal:
sudo kill -STOP `pidof osmo-trx-lms`; sleep 0.5; sudo kill -CONT `pidof osmo-trx-lms`

Change-Id: Idfc4e69acc30afb11440b6b9cbdcfa09ff920265
Since in next commit osmo-trx-lms starts using smpl_buf.cpp, it seems
some automake step doesn't like including a cpp file twice from a
different directory, since race conditions can occur building it.
Instead we define the dependency by first building a static lib and then
using it on each libdevice.la (one per device type).
We already do the similar under arch/ subdir, where we have a common/
subdir and then one subdir and lib per architecture.

Buffer size is based on num of chans and rxBuffer size is based on num
of chans and rx_spp, and both are available and set during open(), so no
need to waste time allocating and freeing them everytime we read from
