We only care about displayable pixel formats (as defined in
WGL_ARB_pixel_format) for window context creation.
This changes pixel format enumeration to ignore non-displayable formats,
which are specified to be listed after displayable ones, by always using
the return value of DescribePixelFormat as the pixel format count.

The native access functions for context handles did not verify that the
context had been created with the same API the function was for.
This makes these functions emit GLFW_NO_WINDOW_CONTEXT on API mismatch.

There is no need to enumerate framebuffer configs that will just be
filtered out later by the GLFW_DOUBLEBUFFER hard constraint.
(cherry picked from commit fd79b02840)
This should have been done when the WGL extension members were moved
from the context struct to the library struct.

Files built for Win32 must use C89 style declarations for compatibility
with VS 2010 and 2012, which are still supported by GLFW.
(cherry picked from commit 56aad76b16)
DWM composition is always enabled on Windows 8 and later, so there's no
need to call DwmIsCompositionEnabled on those platforms.
Fixes#1452.
Closes#1453.
This completes support for window framebuffer transparency on Windows,
macOS and X11. Note that the hint/attribute may be renamed before
release to clarify its relationship to GLFW_OPACITY.

PFN_FunctionName is more readable than SCREAMSOUP_T.
Context creation API function typedefs are kept as-is where the original
header provided them, for compatibility and familiarity reasons.
This removes window re-creation logic by performing the initial context
creation on the helper window, simplifying both window and context
creation and paving the way for attaching to existing window handles
without compromising on context or framebuffer hint support.
