ifpps: Optionally display median values for CPU load and interrupts
Using the -m/--median command line option, median values across all CPUs are displayed for CPU load, interrupts per interval, sw interrupts per interval and absolute number of interrupts. Also update the manpage accordingly. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

And only the reference count of connectors that were previously bound to an encoder and are unbound afterwards should ever be decremented. The reference counts of the temporary copies in the save_connectors should not be touched at all. This patch fixes the above error by only incrementing the reference count of those connectors in the set that are initially not bound to any encoder, and also by restoring the reference count of only those connectors in the set in the failure case. "Note that this can only be hit when fbdev emulation is disabled, since then the refcount drops from 1 to 0 and we call the connector destroy functions on the backup copy, which eventually results in tears. With fbdev emulation the refcount only goes down from 2 to 1 ever. And since we unconditionally increment the refcount on the real object, the refcount of that will slowly increase. The backup connector's refcount doesn't matter, since we kfree() that either way in the end of drm_crtc_helper_set_config()."
