Since there's now a rate counter, we can drop log level for those events
which can be bursty and hence print lots of output in short periods of
time, which may affect performance. This way setting them to INFO it's
enough to avoid getting them in stderr unless explicitly configured by
the user (for instance to debug stuff), while still allowing a good
enough level to be enabled for other targets such as gsmtap.

The queue was being accessed sequentially obtaining and releasing the
mutual exclusion zone twice. First in getStaleBurst() dropping all
FN<currTime, then in getCurrentBurst() trying to obtain FN=currTime.
However, since in between the mutex is released, it could happen that
for instance upper layer would introduce currTime-1 in the queue, which
would make then getCurrentBurst() detect that one instead of potential
currTime in the queue and return NULL.
By holding the mutex during the call to both functions we make sure the
state is kept during the whole transaction.

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.

If more fine-grained results are wanted or some device doesn't follow a

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.

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,

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.

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

TxLower (isUnderrun): RxLower (pullBuffer):
read(underrun) -> true

The underrun parameter in radioDevice's readSamples() is not a "Rx
Underrun" event, but rather it's used to retrieve a "Tx Underrun" which
on some SDRs (like USRP1) seems to be (so far) available only at
readSamples() times.
Thus, underrun parameter for both readSamples() and writeSamples() is
actually flagging the same event, and should be ORed in pushBuffer() as
it's already done in pullBuffer(). Otherwise if implementation is
setting the underrun pointer to false, it could erase the flag being
marked by the counterpart function before isUnderrun() is called (which
is the one responsible to clear the flag).
