This implements core support for priority handling. This is basically the same
as my RFCv3 patch series, except without some of the driver changes (I want to
do that for 2.6.39) and with the single fix to patch 05/16 I posted to the list.
Currently the only drivers this affects are ivtv (which is the only user of
v4l2_fh at the moment) and vivi.
I will probably also adapt cx18 this weekend since as it stands now it is possible
for a lower prio process to change controls for a higher prio process. To fix
this requires core prio handling anyway, so let's get this in for 2.6.38 so
people can start using it.

Hans
