[PATCH v11 03/19] dyndbg: add write-to-tracefs code

adds: dynamic_trace() uses trace_console() temporarily to issue printk:console event uses internal-ish __ftrace_trace_stack code: 4-context buffer stack, barriers per Steve call it from new funcs: dynamic_printk() - print to both syslog/tracefs dynamic_dev_printk() - dev-print to both
