Since we already depend on 'new enough' headers for EGLDeviceEXT you
can use PFNEGLQUERYDEVICEATTRIBEXTPROC and friends. This has the added
benefit of being Windows friendly, if one is building/using libEGL for
the platform - iirc some versions of the Android emulator did.

Don't see the spec mentioning this, but I would make perfect sense.

s/before EGL initialized/with EGL_NO_DISPLAY/ ?
This one isn't covered in the spec either. From mesa POV we won't be
able to get the device if eglInitialize hasn't been called but it
might be worth checking with Khronos/the author(s) and tweak the spec
text ?

Please drop the == EGL_{TRUE,FALSE} hunks

Use piglit_check_egl_error over the direct eglGetError calls ?
