logging: log to stderr when logging is not initialized
When the logging framework is not initialized we get an error:
"ERROR: osmo_log_info == NULL! You must call log_init() before
using logging in ..."
There are sometimes situations where some code tries to log before
logging was initialied. This is a problem because the actual log
line with the debug info we need is covered up by the error message
from the logging framework.
Lets introduce a fallback logging function that is called when the
the logging framework is not available. This function can just use
fprintf to output to stderr.
