It's up to the caller whether it's fatal.  It's a perfectly valid use of
the interface to ignore apr_dso_open() errors; image an application
which optimistically opens a set of named extension modules, some of
which might not be present.  If a particular extension can't be loaded
the app could just ignore it and carry on.  It did *not* ask for stuff
to be printed to stderr, so APR should not do that either.
