Hi,

Here's an update on the EGL/DRM integration extensions and patches.
I've updated the patches with the feedback from the discussions on the
list to the extent that I think is feasible.  I think we're pretty
close to consensus on how to do this, but let me know what you think.
There's also a new extension in the series, the EGL_INTEL_no_surface
extension, which lets us make a context current without a surface.

I updated the eglkms.c test case, and it now compiles and runs against
this patch series:

[PATCH 1/6] egl: Add MESA_typed_display infrastructure

  This is the updated version of the alternative eglGetDisplay
  extension.  I've incorporated the feedback from Chia-I regarding
  naming of the entry point and tokens, and Jakobs suggestion that we
  add tokens for the existing platforms (Win32 and X11).

  It's still a new entrypoint, not separate .so's as Chia-I suggested.
  I don't think it's a terrible idea to have separate .so's with
  different names, but I still like this better, and with separate
  .so's we'll have to compile libEGL several times to output the
  different libraries, which is awkward and a pain for distributions.
  I dropped the XCB display for now.

[PATCH 2/6] egl_dri2: Support EGL_DISPLAY_TYPE_DRM_MESA

  This one just adds support to egl_dri2, should be pretty harmless.

[PATCH 3/6] egl: EGL_INTEL_no_surface extension

  The new extension mentioned above.  It adds a new config attribute
  to inidicate the APIs that support making a context current with
  that config and no surfaces.  Previous discussion on this have
  stalled on the problem that not all client APIs have a meaningful
  way to make a context current without surfaces.  By specifying the
  supported APIs in the config we solve this problem.  See the spec in
  the patch for details.

[PATCH 4/6] egl: MESA_image_drm extension

  This is the extension to create drm images from nothing using
  eglCreateDRMImageMESA, share them using eglShareDRMImageMesa, and
  import them using the EGL_DRM_BUFFER_MESA target with
  eglCreateImageKHR.  Sharing an image is a separate entrypoint
  because a drm buffer doesn't necesarily have a global name and
  creating one is an extra step that we don't always want to incur.

[PATCH 5/6] egl_dri2: Add support for MESA_image_drm

  Nothing to see here, just the implementation.  Some of the
  attrib_list checking could be lifted to egl/main.

[PATCH 6/6] intel: Add support for MESA_drm_image

  The intel dri driver side of things.
