Add two parameters to testpmd:

  --print-event <event name>
  --mask-event <event name>

To enable or disable to printing of events. This display is configured
on a per-event basis. By default, all except VF_MBOX are displayed.

Fixes: 76ad4a2d82d4 ("app/testpmd: add generic event handler")

Additionally, I'm thinking about runtime commands for events, in the form

event <name|all> show
event <name|all> print <bool>

where show could display the state of the display for this event as well
as statistics for the event. print on|off would do the same as the two
parameters introduced by this patch.

But this is a little heavier and I wanted to propose this fix as soon as
possible.

v1 -> v2:

  * Rebased on top of master
  * Fixed typos in doc

v2 -> v3:

  * Fixed doc alignment issues.
