Thanks for looking into this. I agree that the sqlite configuration should be
removed because it only causes confusion at this point. The original intention
was to have backwards compatibility with OpenBTS-style sqlite options, but the
number of users of that approach is approximately -1.

Logging is the other concern. Have you tried removing the configuration
table entirely? The existing queries are rarely, if ever, used. Without
sqlite, the table shouldn't exist at all.

Some general comments. Please remove code when you intend to remove it -
committing commented out lines makes code and the patch difficult to read.
Git will track the changes. Pull requests work well for large commits,
such as sqlite3.c removal.

The shutdown variable is a relic from OpenBTS, and exists because of
the mess involving threads and shutdown. That issue is unrelated to logging or
sqlite.

Please put whitespace / formatting changes in a separate patch. Osmocom
projects generally use kernel style, which becomes somewhat odd and less
strict in the context of C++. In this case, the code change is fine, but don't
add it to an already massive patch.
