It's not available on Win7.

Use the glReserved1 area in the Teb to cache the latest pixel format
information requested from the driver.

Introduce a new wgl driver callback function to allow the driver to provide
a complete list of all pixel formats and their attributes. If the driver
provides the information use it to implement wglDescribePixelFormat.

We want to use wgl_pixel_format in the wgl driver API.

And update tests to show that Windows does the same.

This makes stdole32.tlb generated by widl have proper [in,out,retval]
parameter flags.

It looks like the lowest bit in the param name offset actually indicates
whether type description follows the name, and since the name offsets are
always aligned that makes sense.

This makes oleview.exe from PSDK running under Windows7 correctly show mix
of different very complex and relatively simple type descriptions generated
by widl's SLTG generator.

In source_reader_create_transform(), store the result of
IMFActivate_ActivateObject() so that in the event of failure, resources
are freed and an appropriate HRESULT is returned.

Previously, if every object's activation failed, the last part of the
function was not aware of this.

Note that this won't compile very many shaders until vkd3d-shader's GLSL
support is much more complete.

Much like we do for e.g. shader_glsl_generate_vertex_shader().

The default behaviour for gstreamer is to use the URI to create the
stream-id. Without this, gstreamer creates a random stream-id per pad
which can cause inconsistent ordering on the decodebin src pads.

This in turn can cause issues, for example, with audio stream selection.

This is a partial cherry-pick of eda34f74c6ad from Proton.
