[omxplayer] Always enable timestamp fifo mode.

hints.ptsinvalid is only set for h264 in avi files. However it also can affect any videos with B frames in any container
(we have reports of mp4 and mkv stuttering because of invalid pts values).

To solve this we always enable the timestamp fifo mode, and the gpu treats this as an optional flag, and falls back to non-fifo timestamp
mode if the variance of that timestamp stream is better.

[omxplayer] Fix incorrect settings query that can cause video stutter

A change in CSettings was missed here, and results in the clock component not being configured correctly.
This doesn't apply the correct filtering to clock changes and can create video stutter
[omxplayer] Reduce rate of clock change to reduce video stutters

After analysing some files with video stutter, it was found that the filter coefficients used
for adjusting the clock were set higher than the maximum hdmi clock deviation allowed.

This means when gpu makes small clock adjustments to correct for lip-sync, the video drops frames.

With this patch the frame drops are fixed.

[omxplayer] When setting fullscreen flag we don't want noaspect

We set the fullscreen on 3d videos to avoid scaling breaking the 3d affect.
However we also set the noaspect flag which means widescreen videos (e.g. 1920x800) will get stretched vertically which is unwanted.
