4918430858 msdk: enc: fix missing some frames to be encoded
There was not handling the end of encoding sequence in encoder.
This patch does drain any remaining internal streams while decoder
already does this.

Document says:
"To mark the end of the encoding sequence, call this function with a
NULL surface
pointer. Repeat the call to drain any remaining internally cached
bitstreams—one
frame at a time—until MFX_ERR_MORE_DATA is returned."

ae8d956c2c msdk: encode: Add more rate control options
MediaSDK has support for a number of rate control algorithms.
Adding all possible options to the property rate-control.

Fixme1: In case of failure, currently we don't have a proper method
to show which rate-control has been failed. It could be better
to add some extensive validation on EncQuery output in case of error.
Unfortunately, not all ratecontrol methods are supported by every codecs
and we don't have the dynamic detection of supported ratecontrol methods yet.

f076f1948e msdk: encode: Add property to set slice/partitioning

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.

375a50a876 msdk: add async depth from each msdk element to GstMsdkContext to be shared
In case that pipeline is like ".. ! decoder ! encoder ! ..." with using
video memory,
decoder needs to know the async depth of the following msdk element so
that it could
allocate the correct number of video memory.

Otherwise, decoder's memory is exhausted while processing.

f2b35abcab msdkdec/enc: query GstContext to share GstMsdkContext
How to share/create GstMsdkcontext is the following:

- Search GstMsdkContext if there's in the pipeline.
  - If found, check if it's decoder, encoder or vpp by job type.
    - If it's same job type, it creates another instance of
GstMsdkContext
     with joined-session.
    - Otherwise just use the shared GstMsdkContext.
  - If not found, just creates new instance of GstMsdkContext.

dc82ccb9a2 msdk: context: add job type to figure out if joining session is necessary
According to the driver's instruction, if there are two or more encoders
or decoders in a process, the session should be joined by
MFXJoinSession.

To achieve this successfully by GstContext, this patch adds job type
specified if it's encoder, decoder or vpp.

If a msdk element gets to know if joining session is needed by the
shared context,
it should create another instance of GstContext with joined session,
which
is not shared.

580a52ec49 msdkenc: use bufferpool
1\ Proposes msdk bufferpool to upstream.
  - If upstream has accepted the proposed msdk bufferpool,
    encoder can get msdk surface from the buffer directly.
  - If not, encoder get msdk surface its own msdk bufferpool
    and copy from upstream's frame to the surface.

2\ Replace arrays of surfaces with msdk bufferpool.

3\ In case of using VPP, there should be another msdk bufferpool
   with NV12 info so that it could convert first and encode.

Calls gst_msdk_set_frame_allocator and uses video memory only on linux.
and uses system memory on Windows until d3d allocator is implemented.

6ce9a66b80 msdk: implements GstMsdkContext.
Makes GstMsdkContext to be a descendant of GstObject so that
we could track the life-cycle of the session of the driver.

Also replaces MsdkContext with this one.
Keeps msdk_d3d.c alive for the future.

ddd9355767 msdkenc: handle the MORE_DATA case
If the driver requires more data, just unref the frame at the moment
then retreive/finish the frame after encoding is finished.

This also fixes a memory leak.

dcd9032d95 msdk: enc: set pts and dts, fix inverted sync_point flag
Set the pts and dts on the frame that we receive from the msdk.
Also fix the inverted logic in setting sync points, previously we
were marking all frames as sync points except IDRs.
