From: Steven Rostedt <srostedt@redhat.com>

During testing we often use randconfig to test various kernels.
The current configuration set up does not give an easy way to disable
all tracing with a single config. The case where randconfig would
test all tracing disabled is very unlikely.

This patch adds a config option to enable or disable all tracing.
It is hooked into the tracing menu just like other submenus are done.

[ Impact: allow randconfig to easily produce all traces disabled ]
