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.

Allow selecting a specific LimeSDR device by setting dev-args in the
config file. Split up the given dev-args address by comma and select
the device where all substrings can be found.
I could not test this with real hardware, but I have added a test case
to make sure this works as expected.

Under failure, it could still be that stream status is updated, so let's
father that in all cases.

This change fixes lots of memory leaks inside libLimeSuite as
announced by ASan after exiting the osmo-trx process (throgh
CTRL+C for instance).
This way also we make sure libLimeSuite can communicate with the HW and
close whatever subsystems were enabled during LMS_Open time.

They are recreated during start(). Actually, if they are not stopped
here, during start() after stop(), LMS_SetupStream() will fail because
it will detect the streams are already opened.

So far, the Rx gain was set to 34 dB, wile the comment stated it
would be set to half-point, which is 73/2=36dB. Let's adjust the
code to match the comment.

The following warning was observed with GCC 4.8.5:
make[4]: Entering directory `.../osmo-trx/Transceiver52M/device/lms'
CXX LMSDevice.lo
LMSDevice.cpp: In member function 'LMSDevice::writeSamples()':
LMSDevice.cpp:582:22: warning: 'rc' may be used uninitialized
in this function [-Wmaybe-uninitialized]

Let's fix this by zero-initializing 'rc'.

If LImeSDR device is unplugged or its fw crashes during operation,
reading from the device will fail and will first receive short reads and
finally 0 byte reads. Let's quickly notify these events to upper layers
instead of trying to process the buffer and checking timestamps for
something we know it's already not useful.

The DMAIN category got too overloaded. Let's have the code in
Transceive52M/device/* use the new DDEV category.
Also, in some cases the log levels have been adjusted to ensure
that enabling INFO level should not result in a complete overflow
of messages during normal operation.

Until now, setRxGain in LMSDevice did not take into account the setter
parameter and was always using hardcoded 34dB, which was experimentally
found to be a good default value.
Let's force that value during initialization, but still allow the upper
layers (controlled by BTS) to set different values. osmo-bts only sends
a SETRXGAIN command (which calls setRxGain in osmo-trx) if a value is
explicitly set in its VTY config, so we are on the safe side if the user
doesn't explicitly configure a desired dB.

There might be some configuration that's not supported by osmo-bts-lms,
and we should reject that properly.

In Change-Id Ib2fca81b76d027b08e2891056fa076d071597783 we introduced
some coding style violations. Let's make newly-added code follows
standard Osmocom coding style.

It's not good style to have the derived classes initialize members
inherited from the base class using "this->foo = bar". Rather, let's
make the base class have a constructor, and call that constructor to
initialize the members of the base class.
While doing this
* rename 'offset' to 'lo_offset' to avoid confusion with timestamp offset
* move 'InterfaceType' into the base class
* move 'chans' into the base class
* move 'rx_sps' into the base class
* mark base class members as 'protected'

Before this patch, any configuration in osmo-trx.cfg regarding the rx
and tx "antenna" (path) would have been completely ignored, as the
radioDevice::make() function would simply drop those arguments to the
floor.

Initially, Rx gain was hardcoded to be 47. This was too high for our
setup and we were constantly getting "clipping detected" messages.
Reducing Rx gain to 34 solved the issue. However, it looks like gains
should be controlled through configuration files.

LMS_StartStream() (in LMSDevice::start()) was moved to separate loop. It
is because LMS_SetupStream() would fail for second channel if streaming
has already been started (LMS_StartStream()) for single channel
configuration.

The tx timestamp offset was not set. We set it to the same value as it

As of LimeSuite 618fbb9c3188b36d75ad5785a97b8887dcc468f6, it seems 5e6
is within the returned range, but LMS_SetLPFBW fails anyway.

I'm not quite sure what the ts_offset is for, but by using "0"
we are now receiving exactly the timestamp that we're expecting:
LMSDevice.cpp:486 [tid=140576250332928] chan 0 recv buffer of len 2500 expect 305ed0 got 305ed0 (305ed0) diff=0
Change-Id: I270c94945b1af9662cfc468cfda1ae3af3ac0a27
ts_initial must not point to the timestamp of the first sample
in the last "flush" sample buffer, but to the first timestamp we
expect in the next buffer.

Rx 1.4 MHz, Tx 5MHz. Both massively too wide for GSM, but there's
no smaller band-width available.

LMS_Init() will override basically all device settings with their
default value, including the sample rate. We hence have to make sure
to call it before any other API function that changes the device config
such as sample rate, frequency, filter bandwidth, ...

This is work in progress towards a direct LimeSuite driver in OsmoTRX,
bypassing the currently rather complex stack of wrappers by going
through UHD, SoapyUHD, SoapySDR and LimeSuite.
