e5279cd97a msdk: return the right pointer
The first channel in memory for MFX_FOURCC_RGB4 (VA_FOURCC_ARGB or
GST_VIDEO_FORMAT_BGRA) is B, not A. In MSDK, channle B is used to access
data for RGB4 surface. In addition, the returned pointers for
MFX_FOURCC_AYUV and MFX_FOURCC_Y410 in gst_msdk_video_memory_map_full
were wrong too before this fix.

ce4f9ae531 msdk: fix for mfx frame alloc response
Both MSDK and this plugin use mfxFrameAllocResponse for video and DMABuf
memory, it is possible that some GST buffers are still in use when calling
gst_msdk_frame_free, so add a reference count in the wrapper of
mfxFrameAllocResponse (GstMsdkAllocResponse) to make sure the underlying
mfx resources are still available if the corresponding buffer pool is in
use.

In addtion, currently all allocators for input or output share the same
mfxFrameAllocResponse pointer in an element, so it is possible that
the content of mfxFrameAllocResponse is updated for a new caps then all
GST buffers allocated from an old allocator will use this new content of
mfxFrameAllocResponse, which will result in unexpected behavior. In this
fix, we save the the content of mfxFrameAllocResponse in the corresponding
tructure to avoid such issue

Sample pipeline:

gst-launch-1.0 filesrc location=vp9_multi_resolutions.ivf ! ivfparse ! msdkvp9dec !
msdkvpp ! video/x-raw\(memory:DMABuf\),format=NV12 ! glimagesink

d4112d3d7b msdk: Allow video and system memory share among buffers
gst_buffer_make_writable() requires exclusive reference to the
GstMemory so the _make_writable() for the msdk buffer will result
to fallback system memory copy, because the msdk memory were initialized
with GST_MEMORY_FLAG_NO_SHARE flag.

Note that, disable sharing GstMemory brings high overhead but actually
the msdk memory objects can be shared over multiple buffers.
If the memory is not shareable, newly added GstAllocator::mem_copy will
create copied msdk memory.

ea92da6e54 msdk: dmabuf support
This patch includes:
1\ Implements MsdkDmaBufAllocator and allocation of msdk dmabuf memroy.
2\ Each msdk dmabuf memory include its own msdk surface kept by GQuark.
3\ Adds new option GST_BUFFER_POOL_OPTION_MSDK_USE_DMABUF

c3438b5a0f msdk: generalize the parameter of msdk video memory functions
There needs to be generalized for the parameter from
GstVideoMsdkVideoMemory to GstMemory.

Thus we can call these functions if using DMABuf memory.

b08b8ddae3 msdk: manage MSDK surfaces seperately
Currently a gst buffer has one mfxFrameSurface when it's allocated and
can't be changed.
This is based on that the life of gst buffer and mfxFrameSurface would
be same.
But it's not true. Sometimes even if a gst buffer of a frame is finished
on downstream,
mfxFramesurface coupled with the gst buffer is still locked, which means
it's still being used in the driver.

So this patch does this.
Every time a gst buffer is acquired from the pool, it confirms if the
surface coupled with the buffer is unlocked.
If not, replace it with new unlocked one.
In this way, user(decoder or encoder) doesn't need to manage gst buffers
including locked surface.

To do that, this patch includes the following:
1. GstMsdkContext
- Manages MSDK surfaces available, used, locked respectively as the
following:
  1\ surfaces_avail : surfaces which are free and unused anywhere
  2\ surfaces_used : surfaces coupled with a gst buffer and being used
now.
  3\ surfaces_locked : surfaces still locked even after the gst buffer
is released.

- Provide an api to get MSDK surface available.
- Provide an api to release MSDK surface.

2. GstMsdkVideoMemory
- Gets a surface available when it's allocated.
- Provide an api to get an available surface with new unlocked one.
- Provide an api to release surface in the msdk video memory.

3. GstMsdkBufferPool
- In acquire_buffer, every time a gst buffer is acquired, get new
available surface from the list.
- In release_buffer, it confirms if the buffer's surface is unlocked or
not.
  - If unlocked, it is put to the available list.
  - If still locked, it is put to the locked list.

This also fixes bug #793525.

2542b2d34d msdk: supports bufferpool
Implements 2 memory allocators:
1\ GstMsdkSystemAllocator: This will allocate system memory.
2\ GstMsdkVideoAllocator: This will allocate device memory depending
on the platform. (eg. VASurface)

Currently GstMsdkBufferPool uses video allocator currently by default
only on linux. On Windows, we should use system memory until d3d
allocator
is implemented.
