simpletrace: Move st_init() error reporting
User emulator builds do not have error_report() so it should not be usedby simpletrace.c. In fact, error reporting inside simpletrace.c isinappropriate and should be done by the caller instead.
This patch moves st_init() error reporting out to its caller,...
simpletrace: Thread-safe tracing
