The callback actually belongs there, since it's the code/thread in main the one
actually in charge of stopping everything. It simplifies current code,
and more important, allows for new clients of this signal to use it.
This callback will also be used in forthcoming commits by code
controlling rate_ctr thresholds to stop the process if the VTY
configured threshold is used.

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`
Fixes: OS#3339
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
the device.

ERR is osmo-trx legacy level, which actually converts to osmocom's
ERROR, so let's use that one directly.

* move class definition to .h file, like we do for other devices.
* move smpl_buf class to a different file inside uhd/.
* Preparation work to have smpl_buf being used in a generic way for
devices other than UHD (LMS).

ALERT log level is not Osmocom standard level, it's just a define in
osmo-trx to keep compatibility with old code.
Same goes for one reference to "ERR" intead of "ERROR".

No need to use the heap here since buffer is only used as a temporary
trash. Using the stack is quicker.

add device dependant max gain setup - limesdr mini and limenet micro need slightly reduced maximum gains to get a PASS on phase error measurements
rework clock reference setup - external clock needs to be selected before calling LMS_Init(), internal can only be set after.
remove now unused compat_LMS_VCTCXO* functions - we do not set the VCTXCO directly anymore

move enable: it is important that channels are actually enabled before applying any configuration (besides external clock)
move disable: move to close, so channels are not disabled and not enabled again while osmotrx is active.

We haven't even released any tagged version of libosmocore yet which
includes support for the renamed OSMO_FD_READ constant. Let's avoid
any breakage and use the new constants only with considerable delay,
at the very least only when released libosmocore versions provide it.

Maximum number of carriers is fixed to 3 channels on a single
physical RF channel in multi-ARFCN mode. For some reason, it
was limited to 5.
Let's fix this, and also follow this limitation in the
following VTY command handlers:
- cfg_multi_arfcn_cmd,
- cfg_chan_cmd.

This should avoid prolematic scenarios where different signal handlers
are running on different thread in parallel. Furthermore, we make sure
those signals are always run by main loop thread.

Recently a blocked osmo-trx process was found after ending SIGTERM to
it.
Apparently one thread was handling SIGTERM and calling fprintf()
(grabbing libc lock) while another thread was handling another signal
and also grabbing similar lock. Both thread looked deadlocked there.
Probably this change doesn't fix the block on its own, but at least
simplifies scenarios inside signal ctx which can go wrong.

Besides just general cleanup, the major changes are :
- Fully internal generation of reference data that doesn't
depend on glibc or even on any floating point math
- Golden results are included in a .h
Due to varying precision of different implementation or
architecture, any kind of textual compare is impossible, so
we include golden values and compare results of both the
'base' implementation the potentially 'optimized' one again
this set of values with a small error tolerance

Since I838c21db29c54f1924dd478c2b34b46b70aab2cd we have both TS1
and TS2 synch. sequences, in addition to "default" TS0. Let's
finally introduce the VTY configuration parameter, that can
be used to toggle optional detection of both TS1 and TS2.
Note: we keep this optional because of potentially bad impact on
performance. There's no point in paying the performance penalty
unless upper levels (BTS, PCU) actually make use of it.

There appears to have been some logic to operate a USRP1 in
transmit-only GSM mode. This is achieved using the skipRx member
of the transceiver object. However, there's nobody that ever
initializes it properly, and hence the feature is not possible to
use anyway.
I don't think this has any valid use case, so let's remove it.

boost is only used in USRPDevice class.
It looks like it can be removed entirely quite easily, since only
boost::shared_ptr is used for 2 variables. That's left for somebody with
the device and willingness to test the changes.
