7b9debedc8 d3d11: Don't use hardcoded maximum resolution value
Maximum supported texture dimension is pre-defined based on
feature level and it couldn't be INT_MAX in any case.

0f7af4b143 d3d11: Move core methods to gst-libs
Move d3d11 device, memory, buffer pool and minimal method
to gst-libs so that other plugins can access d3d11 resource.
Since Direct3D is primary graphics API on Windows, we need
this infrastructure for various plugins can share GPU resource
without downloading GPU memory.
Note that this implementation is public only for -bad scope
for now.

59a1897c39 d3d11: Privatize d3d11memory implementation
Hide most of symbols of GstD3D11Memory object.
GstD3D11Memory is one of primary resource for imcoming d3d11 library
and it's expected to be a extensible feature.
Hiding implementation detail would be helpful for later use case.

Summary of this commit:
* Now all native Direct3D11 resources are private of GstD3D11Memory.
  To access native resources, getter methods need to be used
  or generic map (e.g., gst_memory_map) API should be called
  apart from some exceptional case such as d3d11decoder case.
* Various helper methods are added for GstBuffer related operations
  and in order to remove duplicated code.

a9314b4554 d3d11upload/d3d11download: Make use of staging buffer
... instead of direct cpu map for d3d11memory object. In this way,
we don't need per GstD3D11Memory staging texture.

ea24a2e527 d3d11: Add support for packed 8bits 4:2:2 YUV formats
Note that newly added formats (YUY2, UYVY, and VYUY) are not supported
render target view formats. So such formats can be only input of d3d11convert
or d3d11videosink. Another note is that YUY2 format is a very common
format for hardware en/decoders on Windows.

9b72b04dad d3d11download: Allow linking with downstream d3d11 elements
It will make pipeline configuration easier since d3d11download
element can be placed unconditionally. This behavior is similar
to that of gldownload element.

9ee40679b5 Revert "d3d11: Add support for D3D11_USAGE_DYNAMIC"
This reverts commit ddd13fc7c0

Dynamic usage can reduce the number of copy per frame but make
things complicated and the benefit seems to not significant.
Also since we don't provide _map() method for the dynamic usage,
application cannot read buffers which make "last-sample" property
unusable in case of d3d11videosink.

81dde0f5b8 d3d11: Aggregate d3d11 memory usage query for dynamic-usage type decision
Even if one of downstream d3d11 elements can support dynamic-usage memory,
another one might not support it. Also, to support dynamic-usage,
both upstream and downstream d3d11device must be the same object.

0788492461 d3d11: Use GRecMutex to protect immediate context and dxgi API call
In some cases, rendering and dxgi (e.g., swapchain) APIs should be
called from window message pump thread, but current design (dedicated d3d11 thread)
make it impossible. To solve it, change concurrency model to locking based one
from single-thread model.
