Alexis Berlemont 21e8c81095 perf hists browser: Dynamically change verbosity level
Here is a small patch which tries to fulfill a point in the perf todo
list:

* Make pressing 'V' multiple times to go on cycling thru various
  verbosity levels in 'perf top', so that info that is present in
  'perf top -v' can be obtained without having to restart the tool
  (acme).

After a small grep in the code, the max verbosity level seems 3; so,
we cycle at 4; I did not dare define a MAX_VERBOSE_LEVEL constant.
