All radioDevice subclasses except USRPDevice have already been reworked
to use the new SetPowerAttenuation() methods, hence we can drop the
compatibility layer that was added to transition from the old API to the
new one, and move those functions to USRPDevice.
This way we simplify the parent abstract class with methods not needed
by most devices and not used anymore by external users of those classes.

Right now, according to a few measurements taken on LimeMicro devices, we
expect the Tx Gain at UHD level to relate 1:1 with the slope in Tx output
power given a specific band.
If more fine-grained results are wanted or some device doesn't follow a
1:1 slope relationship, functions TxGain2TxPower and TxPower2TxGain need
to be adapted/improved.
This patch is basically doing the same thing as was done previously for
UHDDevice in 992c9bd1ce.

All the Tx gain related APIs are left out of reach from radioInterface,
and in there we simply interact with radioDevice passing the attenuation
received from TRXC.
Prior gain logic is moved in base radiodevice class, with the idea that
the setTxGain() and related functions will be dropped over time in each
sublcass in favour of an specific implementation of the
SetPowerAttenuation API.

It allows the BTS to retrieve the nominal transmit output power value of
each TRX in order to compute attenuation later on and apply it through
SETPOWER or ADJPOWER TRXC commands.

When the logging category TRXCLK is set to info osmo-trx prints a
logline that informs about the sending of clock indications. In practice
this those log lines are often used to identify that osmo-trx and
osmo-bts are running properly, so it would be helpful, even in
productive use, if there would be an information in the log that the
sending of clock indications has begun. However, the regular printing of
the clock indication log line would soon flood the log. So, lets have an
addional log line that logs only once when the transceiver starts and
quickly informs at loglevel NOTICE that clock indications are now sent.

New define is available since libosmocore 1.1.0, and we already require

There is no need to have n threads handle n ctrl sockets, since they all
will immediately respond to commands, so handle them from the existing
main osmo select loop.
Care must be taken to ensure that calls from within the command handler
do not block, or at least don't block too long, which currently is the
case.

The out "isControl" parameter is only used by internal callers of
USRPDevice, and not used at all by any user of the generic API
(radioInterface*.cpp). Hence, we can get rid of it and keep it as a flag
for an internal API of USRPDevice.

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

LimeNet-micro coefficients have yet not been tested.

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.

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.

multi-arfcn feature uses a hardcoded disposition of logical channels on
a physical channel. Logical channels in the phisical channel are
separated by MCBTS_SPACING Hz, that is 4 GSM ARFCNs.
As a result, multi-arfcn restricts the TRX ARFCN setup to the following:
ARFCN(TRX0)=N, ARFCN(TRX1)=N+1*4, ARFCN(TRX2)=N+2*4, ...
Let's make sure radioInterfaceMulti verifies the requested Rx/Tx
frequencies for each logical channel over TRXC match the restriction
explained above. It will check freq going to be set is indeed separated
by MCBTS_SPACING from already set channels, making sure the ARFCN series
is consistent.
Otherwise, before this patch, one could set in osmo-bsc:
ARFCN(TRX0)=N, ARFCN(TRX1)=N+2
and osmo-trx would silently ack the related Rx/TxTUNE TRXC commands, but
actually still transmit on ARFCN N+4 instead. As a result, in this
scenario TRX!=0 were unusable with multi-arfcn.

In the command line options time, filler table/filer burts settings
were a bit difficult to undertand because the number of one-letter
settings was limited. Now, with VTY configuration, there is no reason
to keep it so difficult.
Also, after the previous commit it was no longer posible to enable
random 8-PSK filler bursts. With this patch you can configure all
supported filler bursts in a simple and logical way.

Since libosmocore Id7711893b34263baacac6caf4d489467053131bb, a new API
log_enable_multithread() is available which takes care of protecting
logging infrastructure from us (and actually does it correctly since we
cannot protect internal libosmocore structures from osmo-trx).
Let's drop all mutex related code from osmo-trx logging infra and simply
rely on libosmocore's.

Otherwise, it could happen that underrun events are lost:
TxLower (isUnderrun): RxLower (pullBuffer):
read(underrun)
read(underrun)
write(underrun, |val) [maybe underrun becomes TRUE]
write(underrun, false)
Similary, it could happen the other direction if atomic was only applied
to isUnderrun:
TxLower (isUnderrun): RxLower (pullBuffer):
read(underrun) -> true
read(underrun)-> true
write(underrun, false)
write(underrun, true|val) where val=false
So in here isUnderrun would return true twice while it should only
return one.

In multi arfcn mode, osmo-trx would drop some bursts because it couldn't detect it

vector failed. Correcting copying of history in pullBuffer method fixes this issue.
