I am setting out to refactor various details about logging. To show the effect,
I am first adding this new test to illustrate the exact effects on the various
osmo programs.
Add logging_vty_test.c as a standalone program that simply defines a few
logging categories and opens a telnet vty to play with.
Add logging_vty_test.vty, as an osmo_verify_transcript_vty.py test script.
Add --enable-external-tests to configure.ac, to enable running
logging_vty_test.vty during 'make check'.
Also allow running 'make vty-test' without the need to first configure with
--enable-external-tests (a flexibility I've missed many times over in the other
osmo source trees).
Add a Makefile.am stub for external CTRL tests, basically a copy-paste from
osmo-msc.git. I doubt that libosmocore will get python driven CTRL interface
testing any time soon, but if so we will know to not run it concurrently.
