[PATCH 7/9] perf (userspace): Introduce --verbose param for perf timechart

[Thomas Renninger]

by making use of the already available global verbose variable
from util/debug.h (similar to perf diff or perf top).

Some already introduced if (verbose) condtitions in util/svnhelper.c
will also be activated with that one.
