First of all, it was found that vty allocation must be forced (-t -t)
during ssh session creation to make sure SIGHUP is forwarded when
session is closed.
Second, since osmo-trx ignores SIGHUP (osmo_init_ignore_signals()), we
must add a wrapper script which converts received SIGHUP into a SIGINT
to stop osmo-trx.

2nd TRX arfcn is changed in defaults.conf because multi_arfcn requires
them to be alocated in steps of 4 starting from TRX0.
It is not enabled by default yet on B200 (it must use it to support
several TRX) because current host running osmo-gsm-tester is not
performant enough and cannot keep up with timers due to multi-arfcn CPU
overhead.

* This commit is a preparation for future commits to add support for
different osmo-trx devices and backends like osmo-trx-lms.
* Drop deprecated osmo-trx-* cmd line params and use VTY cfg to set them.
* As number of osmo-trx related osmo-gsm-tester attributes grow, group
them togther in an "osmo_trx" dictionary.

After bug described in OS#3456 and fixed in last commit, let's
categorize and place variables in its correct plac to avoid similar
issus. We leave under the class keyword (class scoped variables) the
attributes which are to be used as static class attributes. All other
ones are initialized during __init__(). This way w avoid scenarios in
which while using an object from an instance attribute we end up reading
a class scoped variable which is shared among all instances.

Some tests may want to reproduce some scenarios in which it is expected
that a BTS process is stopped, for instance if the BSC link is dropped.
Provide a keepalive parameter to start() for bts and pcu objects to
inform suite that failures are expected and that it should keep them
alive in case that ocurrs by respawning the BTS process.

A lot of code can be shared by all osmocom related BTS we currently use
(sysmo, octphy, trx). This commits moves all this easily shareable code
to an abstract class OsmoBts which all (osmocom) BTS use.
Some bits of code do not apply for osmo-bts-sysmo but it's still shared
by BTS running in the main unit (octphy, trx), for instance the pcu
socket handling. Those are put together in OsmoBtsMainUnit.
This way we have:
log.Origin<-OsmoBts<-OsmoBtsMainUnit<-OsmoBtsOctphy
log.Origin<-OsmoBts<-OsmoBtsMainUnit<-OsmoBtsTrx
log.Origin<-OsmoBts<-OsmoBtsSysmo
Also take the chance to categorize the different APIs in the new
abstract class based on their use and scope.
Some code changes while moving which were required:
- A new protected abstract API "create_pcu", which returns an object of
"pcu" interface. Subclasses implement this API returning either a
PcySysmo or a PcuOsmo object. This is needed to abstract the pcu()
getter into the base class.
- For BTS running in the main unit, pcu_sk_tmp_dir object is allocated
when first used (API pcu_socket_path()) instead of doing it in the
constructor. This is moved into OsmoBtsMainUnit

This is required to start osmo-pcu after osmo-bts is already setup and
activated. Otherwise osmo-pcu ends after connecting to socket with:
"pcu_l1_if.cpp:416 BTS not available"

This is a first step to add support for osmo-bts-octpy to
osmo-gsm-tester.
There's no point in building separate insts for different osmo-bts
variants which run on the main unit and which come from the same git
repository, this we make the osmo-bts-trx one generic to handle all
variants which fall into the description above.
Tested locally on my laptop that it builds susccessfully.
Once this patch is applied, jenkins jobs need to be adjusted:
- RnD: osmo-gsm-tester_manual-build-all
- Prod: osmo-gsm-tester_build-osmo-bts-trx (and rename it)

We are currently seeing this issues in prod setup, which uses python
3.4:
File "/home/jenkins/workspace/osmo-gsm-tester_run/osmo-gsm-tester/src/osmo_gsm_tester/bts_osmotrx.py", line 44, in __init__
self.pcu_sk_tmp_dir = tempfile.mkdtemp(None, 'ogtpcusk', None)
File "/usr/lib/python3.4/tempfile.py", line 432, in mkdtemp
file = _os.path.join(dir, prefix + name + suffix)
TypeError: Can't convert 'NoneType' object to str implicitly
Acording to mkdtemp man in python3:
"Changed in version 3.5: suffix, prefix, and dir may now be supplied in
bytes in order to obtain a bytes return value. Prior to this, only str
was allowed. suffix and prefix now accept and default to None to cause
an appropriate default value to be used."
This issue went unnoticed because the RnD env is running debian 9, which
probably has python version >= 3.5.

In commit 329b6f4 pcu-socket path was moved to run inside the test run
dir to avoid issues between different tests creating a socket in the
same place.
However, it seems unix sockets paths are limited to 108 bytes (with Null
char included). In some cases, the run dir for a test can be quite long,
as it contains suite name, test name, etc. and the path can be longer
that the limit defined above.
In order to fix this issue, create a tmp dir using mkdtemp to ensure the
path to be used for the pcu-socket doesn't collide between different
instances of osmo-bts-trx.
Clean up of tmp dir and pcu socket is done inside the cleanup() method
called by suite.py.
method pcu_socket_path() is added to help with new implementation, and
it will be used as well as a public API later soon to be used by OsmoPcu
classes.

We may want to support running a device which runs its own TRX
(osmo-trx or different implementation). Furthermore, this TRX may be
available in some specific hwardare rather than on the main unit.
This makes it easy to configure OsmoBtsTrx to launch it's own
osmo-trx or not. In case it is launched, all IPs are configured correctly
to ensure connection can be established.
Before this commit, osmo-trx was binding to 127.0.0.1. Now we can
support multiple osmo-trx being launched on the main unit.

When splitting osmo-trx to its own class the env injection part was
removed because it seemed not needed as it has no dependencies included
by default in the trial.
However, it may still be required by the osmo-gsm-tester main unit to
launch osmo-gsm-tester with LD_PRELOAD_PATH to point to specific
versions of libuhd, so let's add the env injection back in there.

Otherwise osmo-bts stores the socket file in /tmp. If an earlier
instance doesn't finish cleanly, the file is left there and a new
instance will fail to start because it cannot create a new socket file
in the same place.

Processes created have the scope of the test, so we should store
everything in a per-suite_run/per-test directory, otherwise everything
is stored in the same trial run_dir directory and it's really messy.

We get sporadic clock skews when running osmo-bts-trx, causing the process to
end and the test to fail. Try to give some seconds for the osmo-trx process to
sort itself out, in the hope to avoid the clock skews.

With the recent fix of the junit report related issues, another issue arose:
the 'with log.Origin' was changed to disallow __enter__ing an object twice to
fix problems, now still code would fail because it tries to do 'with' on the
same object twice. The only reason is to ensure that logging is associated with
a given object. Instead of complicating even more, implement differently.
Refactor logging to simplify use: drop the 'with Origin' style completely, and
instead use the python stack to determine which objects are created by which,
and which object to associate a log statement with.
The new way: we rely on the convention that each class instance has a local
'self' referencing the object instance. If we need to find an origin as a new
object's parent, or to associate a log message with, we traverse each stack
frame, fetching the first local 'self' object that is a log.Origin class
instance.
How to use:
Simply call log.log() anywhere, and it finds an Origin object to log for, from
the stack. Alternatively call self.log() for any Origin() object to skip the
lookup.
Create classes as child class of log.Origin and make sure to call
super().__init__(category, name). This constructor will magically find a parent
Origin on the stack.
When an exception happens, we first escalate the exception up through call
scopes to where ever it is handled by log.log_exn(). This then finds an Origin
object in the traceback's stack frames, no need to nest in 'with' scopes.
Hence the 'with log.Origin' now "happens implicitly", we can write pure natural
python code, no more hassles with scope ordering.
Furthermore, any frame can place additional logging information in a frame by
calling log.ctx(). This is automatically inserted in the ancestry associated
with a log statement / exception.

The "Affero" nature makes sense for the Osmocom network components like
BSC, SGSN, etc. as they are typically operated to provide a network
service.
For testing, this doesn't make so much sense as it is difficult to
imagine people creating a business out of offering to run test cases on
an end-to-end Osmocom GSM network. So let's drop the 'Affero' here.
All code is so far developed by sysmocom staff, so as Managing Director
of sysmocom I can effect such a license change unilaterally.

To start an MGCPGW, we so far need the BTS address in advance (should get fixed
at some point, but so far we do).
The sysmoBTS has a fixed IP address configured. The osmo-bts-trx so far always
uses 127.0.0.1 (should also be fixed at some point). Both now return this
address with the remote_addr() function.
This also replaces a SysmoBts.remote_addr member variable (which is not
sufficient because it is only populated during configure()).

A NITB is a BSC + MSC, and if a BTS talks to a NITB, it talks to the BSC part
of the NITB. Hence it makes more sense to name certain things 'bsc' instead of
'nitb', to prepare for a separate BSC process appearing soon.

able to run it because it is overwriting the previous variable.

Clearly separate the kinds of BTS hardware the GSM tester knows ('type') from
the NITB's bts/type config item ('osmobsc_bts_type' -- not 'osmonitb_...' to
stay in tune with future developments: it is the libbsc that needs this).
For BTS hardware kinds, use the full name of the binary for osmo driven models:
osmo-bts-sysmo, osmo-bts-trx, osmo-bts-octphy.
