Frame counters can overflow relatively easily (INT_MAX number of frames is
slightly more than 1 year for 60 fps content), so make sure we use 64 bit
values for them.

Previous version of this patch series was on the mailing list for 2 weeks, and did not receive any objection (unlike the alternate version of this patchset earlier) so I plan to apply this version in a couple of days, if people still not raise any concern.

Thanks,
Marton


Also deprecate the old 32 bit frame_number attribute.
