This method replace the manual adjustment of PTS and DTS to avoid
negative DTS issues. Using this method will also update the segment so
we don't loos sync.

Provide new frame-packing property to directly set
x264enc frame packing, or pass through upstream settings
The explicit layout from the frame-packing property is
preferred over any info from the caps.
Currently we only shift DTS to compensate that we don't support negative
timestamp. This cause a problem that PTS is no longer >= DTS and may
make muxers live much harder. Instead, shift both PTS/DTS forward. Also
remove all the hack to handle this which seems the result of thinking libx264
is bugged.

Makes x264 select its stream-format based on what's available
on caps, the user selected option will be chosen as a fallback
when both options are available.

Use of a rate control method (pass, bitrate, quantizer, etc properties), a
preset and possibly a profile and/or tuning are now the recommended way to
configure x264 through x264enc.
If a preset/tuning are specified then these will define the default values and
the property defaults will be ignored. After this the option-string property is
applied, followed by the user-set properties, fast first pass restrictions and
finally the profile restrictions.
Addresses part of bug #607798
- Make defaults append the appropriate default value to a string. This is
needed to differentiate between something user-set and the actual prop
default.
- Add an internal option string to which _set_property () cases append for the
majority of properties.
- Use gst_x264_enc_parse_options () to clean up application of settings. This
will make order of application with respect to the presets and tunings quite
simple.
Addresses part of bug #607798
In X264_BUILD >= 86 there is a new API for applying restrictions to an H.264
Profile. This makes it easier to achieve Baseline Profile for example.

* ext/x264/gstx264enc.h:
Do not deal with duplicated input (timestamps). If needed,
a generic element can do so.
Do not manipulate input timestamps on the way out,
since that shifts the timeline and A/V sync.
