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.

Add -c cmdline option to do the same as / in addition to the
OSMO_GSM_TESTER_CONF var, because setting the var is cumbersome in daily
development.

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.

Tweak test expectations to include the new debug logging.
Go through the paths in alphabetical order to get deterministic logging output,
so the test expectations always match.

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.

The original osmo-gsm-tester was an internal development at sysmocom, mostly by
D. Laszlo Sitzer <dlsitzer@sysmocom.de>, of which this public osmo-gsm-tester
is a refactoring / rewrite.
This imports an early state of the refactoring and is not functional yet. Bits
from the earlier osmo-gsm-tester will be added as needed. The earlier commit
history is not imported.
