Pau Espin 1fba10409b Transceiver: Fix logging TN and version
Since tn is declared as uint8_t, it's actually a char, and by default
c++'s ostream& operator<<(ostream&, unsigned char) tries to print chars
with its ASCII visible character instead of numeric value.

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).

Pau Espin 4e6ec4554d Transceiver: Fix idle ul burst indications being dropped
pullRadioVector() should return true on idle frames because those
indications may be handled by upper layers (TRXDv1). Clarify return code
in function documentation.

Pau Espin ca6a78e193 Transceiver: fix segfault during init if IP addr binding fails
If osmo-trx is started and IP addr binding fails (ie because the IP
address is not assigned in the system), it will try to access a
heap-allocated Thread instance which was not initialized (because init()
function returned earlier).

Pau Espin 67aa91b2c0 Drop old setPriority related code
This code is not needed anymore since we are setting SCHED_RR scheduler
with a real time priority in main thread during startup, so all threads
will inherit same rt priority, which should be enough to keep the
process working reliably even on high system loads (from non rt
processes).

osmo-trx was tested to be reliable during test with stress-ng as
explained in related ticket below.

Previous commit started using IPPROTO_UDP without including required
include. Newer versions of libosmocore's osmocom/core/socket.h include
that header so the define is present, but older versions of libosmocore
(such as 0.12.0) don't, so let's include it explicitly (the correct
thing to do).

TransceiverChannel naming was misleading there. It's simply a data type

function, so let's clearly specify is a storage for thread params.
Furthermore, we don't need a full C++ class for that, let's simply use a
struct.

>>>     CID 200212:  Uninitialized members  (UNINIT_CTOR)
>>>     Non-static class member "mExtRACH" is not initialized in this constructor nor in any functions that it calls.

The current status is actually harmless since the field will be set
during init() time, and the variable is never used before init() is
called.

Make the interface using trx_ul_burst_ind more implementation agnostic
as well as easier to use. For instance, we don't care about SoftVector
size one returned from pullRadioVector(); we want to use nbits instead.
As a result, we no longer spend time normalizing guard periods. While at
it, change vectorSLicer to return void since it always returns true.

A new struct trx_ul_burst_ind is introduced, which will handle
information filled by lower layers upon decoding of uplink bursts.

Methods pullRadioVector() and logRxBurst() are adapted to use that
struct. This way it's easier to understand in/out parameters and it's
also easier to add further parameters to be filled in in the future.

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.

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.

Pau Espin 5b60c98769 Use pthread_setname_np to name threads
osmo-trx can start a considerable amount of threads that can make
debugging it challenging at least. By using phtread_setname_np, the
system sets a meaningful name to the thread which can be seen while
debugging with gdb or by printing /proc/$pid/task/$tid/comm.

Now we also log system TID when setting the name so we can identify
different tasks in /proc even if pthread_setname_np fails.

Pau Espin db936b9b55 osmo-trx: Add osmo_signal to stop whole transceiver chain correctly on error
Transceiver::stop() can only be called from either CTRL iface thread or
from main thread (running osmocom loop). That's because stop attempts to
cancel and then join all the other threads, which would then lock if
attempting to stop from some of them.
As a result, the best option is to indicate to the user of the
transceiver option (osmo-trx.cpp) to stop it in a correct fashion by
destroying the object from the main thread.
