[PATCH 4/7] tracing: make print_(b)printk_msg_only global

[Steven Rostedt]

From: Steven Rostedt <srostedt@xxxxxxxxxx>

This patch makes print_printk_msg_only and print_bprintk_msg_only
global for other functions to use. It also renames them by adding
a "trace_" to the beginning to avoid namespace collisions.
