[PATCH 2/8] trace-cmd library: Add tracecmd_info() log function

["Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>]

The pr_stat() function is removed from the traceevent library. This function
was used by trace-cmd to print statistics. Introduce tracecmd_info() log
function and replace pr_stat() with it in the trace-cmd library.
However, pr_stat() is used also in the trace-cmd application. In order no
to change the existing behaviour, add a static pr_stat() implementation for
that usage.
