d99e97af80 msdkh264enc: add dblk-idc property 
The SDK can support deblocking reference structure [1], so add a new
property to enable this feature.

be1f66a491 msdkenc{h264,h265}: add intra-refresh-type property 
The SDK allows user to specify the intra refresh type which can improve
error resilience without significant impact on encoded bitstream size
caused by I frames [1]

1f1a5b4ad1 msdkenc{h264,h265}: add min-qp and max-qp properties 
The SDK allows user to set a QP range [1], so add min-qp and max-qp to
sepecify QP range. By default, there is no limitations on QP.

55f3590317 msdkenc: support tune property in msdkh264enc and msdkh265enc 
Introduce a new property for encoding mode selection, the default value
for this new property allows the SDK to decide what to do. In addition,
low-power is marked as deprecated since this fix

e924dec4e1 msdk: h264_enc: Enable B-pyramid prediction support 
Since there is already an "adaptive-B" option, just
use boolean property for B-pyramid enabling.

Fixme: Not sure whether this can be supported in vp8 and vp9.
It could be possible through GPB (b without backward ref) but
can't verify currently. We can move this as common property
once verified with vp8 and vp9 without breaking any backward
compatibility.

f25bcf7cb8 msdk: h264_enc: Add slice size tuning option 
According to spec, it is a general property. But based on
testing it only works for h264 encoder.
Let's keep it as h264 specific for now.

b7dbcb26b8 msdk: encoder: h264: Enable trellis quantization tuning 
Add a new property "trellis" to enable trellis quantization.
Keeping trellis as a flag value (which is boolean for gst x264 enc element)
since it is possible to enable/disable this seperately for
I,P and B frames through MediaSDK ext option headers.

The subclass implementations always need to inform base-encoder
if it requires the inclusion of Extend Header buffers (mfxExtCodingOption2
 and mfxExtCodingOption3).

d58c0bd509 msdk: h264_enc: Add LookaheadDownsampling support 
This option controls down sampling in look ahead bitrate
control mode. According to spec it is only supported in AVC.

Fixme: Probably HEVC also have support for this in recent
MSDK versions. We could move the enumeration types to common
header usable for multiple codecs.

fa0911c3f6 msdk: encoder: register only the required properties 
The base encoder common properties are not valid for
mjpeg encoder where there is no motion compensation or rate control.
Delaying the property installation on the base gobject
untill the subclass class_init get invoked.

that's not the case nowadays.
