This sequence of event/data flow might happen
1) Initially we have one pending output event
1-1) Then, process the pending output data
2) No pending input event, then we should wait new pending input event
2-1) Wakeup by new pending event (but it's pending output event)
In above case, MFT will not report new pending input event
if pending output is not processed.

Add a new wasapi implementation mainly to support UWP application.
Basically the core logic of this plugin is almost identical to
existing wasapi plugin, but main target is Windows 10 (+ UWP).
Since this plugin uses WinRT APIs, this plugin most likely might not
work Windows 8 or lower.
Compared with existing wasapi plugin, additional features of this plugin are
* Fully compatible with both Windows 10 desktop and UWP application
* Supports automatic stream routing (auto fallback when device was removed)
* Support device level mute/volume control
But some features of existing wasapi plugin are not implemented
in this plugin yet
* Exclusive streaming mode is not supported
* Loopback feature is not implemented
* Cross-compile is not possible with current mingw toolchain
(meaning that MSVC and Windows 10 SDK are required to build this plugin)

d3d11videosink has an advantage over d3dvideosink, such as
* Zero-copy playback with d3d11 decoders
* HDR rendering with 10-bit format/swapchain support
* UWP support
* Any system memory alignment/padding can be supported
* User can select target GPU device
And old d3dvideosink's functionality (e.g., navigation event, overlaycomposition)
can be covered by d3d11videosink

all msdk output surfaces come from out_alloc_resp, so the buffer count is not resizable.
we need set min_buffers, max_buffers to same size.
steps to reproduce
1. ffmpeg -f lavfi -i testsrc=duration=10:size=320x240:rate=30:decimals=3 -pix_fmt yuv420p -c:v libx265 ~/bits/hevc/test.265
2. GST_GL_PLATFORM=egl gst-launch-1.0 -v filesrc location=~/bits/hevc/test.265 ! h265parse ! msdkh265dec ! msdkvpp ! queue ! glimagesink
you will see error like this:
ERROR default gstmsdkvideomemory.c:77:gst_msdk_video_allocator_get_surface: failed to get surface available
ERROR msdkbufferpool gstmsdkbufferpool.c:270:gst_msdk_buffer_pool_alloc_buffer:<msdkbufferpool2> failed to create new MSDK memory

The unit tests only checked for vulkan_dep.found(), which can
be true if the libs are there but glslc was not found, in which
case the plugin wouldn't be built and the unit tests would fail
because of missing vulkan plugins.
Doesn't really make much sense to build the vulkan integration lib
either if we're not going to build the vulkan plugin, so just disable
both for now if glslc is not available.

34af8ed66a changed the code to use the
packetizer's packets instead of the incoming buffers, but mpegtsbase
didn't actually push all packets to the subclass. As a result, padding
(PID 0x1FFF) packets got lost.
Add a new boolean to toggle pushing unknown packets to mpegtsbase and
have mpegtsparse make use of it.

If core is built as a subproject (e.g. as in gst-build), make sure to use
the gst-plugin-scanner from the built subproject. Without this, gstreamer
might accidentally use the gst-plugin-scanner from the install prefix if
that exists, which in turn might drag in gst library versions we didn't
mean to drag in. Those gst library versions might then be older than
what our current build needs, and might cause our newly-built plugins
to get blacklisted in the test registry because they rely on a symbol
that the wrongly-pulled in gst lib doesn't have.
This should fix running of unit tests in gst-build when invoking
meson test or ninja test from outside the devenv for the case where
there is an older or different-version gst-plugin-scanner installed
in the install prefix.
In case no gst-plugin-scanner is installed in the install prefix, this
will fix "GStreamer-WARNING: External plugin loader failed. This most
likely means that the plugin loader helper binary was not found or
could not be run. You might need to set the GST_PLUGIN_SCANNER
environment variable if your setup is unusual." warnings when running
the unit tests.
In the case where we find GStreamer core via pkg-config we use
a newly-added pkg-config var "pluginscannerdir" to get the right
directory. This has the benefit of working transparently for both
installed and uninstalled pkg-config files/setups.

Add MediaFoundation AAC encoder element.
Before Windows 10, mono and stereo channels were supported audio channels
configuration by AAC encoder MFT. However, on Windows 10,
5.1 channels support was introduced.
To expose correct range of support format by this element
whatever the OS version is, this element will enumerate
all the supported format by the AAC encoder MFT
and then will configure sink/src templates while plugin init.
