Pau Espin 553a25033e Use new libosmovty cpu sched config features
Using the new libosmovty features allow for:
* Setting different cpu-affinity masks for each thread in the process,
  both at startup through .cfg file as well as changing it at runtime.
* Unified VTY interface to change the scheduling policy of the process
  inherited by all osmocom processes enabling the feature.

Pau Espin 1d165a043e Transceiver: Add several rate_ctr for rx error conditions
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.

Pau Espin df675784a7 Transceiver: Restrict conditions where FN gaps are detected
In pushRadioVector, like we did for driveTxPriorityQueue already, gaps
are possible in any channel for TRX!=0, since TRX0 is the only one
expected to be always transmitting.

Since we always need to transmit there, it makes no sense to check for
channel being not NONE.

Pau Espin 8b0c5368f5 Transceiver: Fix race condition obtaining Dl burst from Upper layer
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.

basically counts if burstrs from it arrived too late to osmo-trx.

Philipp Maier fdefbfac39 Transceiver: Log when sending of CLK indications begins
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.

Eric Wild a7143bf7a1 transceiver: get rid of the ctrl threads
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.

Pau Espin 76ff96e210 Transceiver: exit process when BTS drops connection
We don't want to keep osmo-trx running in a started state once the BTS
controlling it becomes unavailable. If a socket towards the BTS fails,
it means the BTS is gone and the best thing to do is to stop the process
(alternatively we could go back to stopped state instead, and wait for
BTS to re-connect, fur so far this action is good enough).
