When osmo-remsim was originally developed, libosmocore logging was
not yet thread-safe. This meant that the worker threads of remsim-bankd
and remsim-server could not log via the libosmocore logging framework
but directly used stderr/stdout, which produced rather inconsistent log
output.
However, since 1.3.0, libosmocore has received support for
multi-threaded applications. Let's make use of this and consistently
use it in remsim-server and remsim-bankd. This obviously also means
adding some more log categories.
