A convenience function/macro to log a normal message.
g_log_default_handler() is used as the log handler function, a new-line
character will automatically be appended to @…, and need not be entered manually.
If structured logging is enabled, this will use g_log_structured(); otherwise it will use g_log(). See [Using Structured Logging][using-structured-logging].
This function is not directly available to language bindings.
