v2:
   - compile only on platforms that have drm (Eric)
   - use standard drm definitions for fourcc instead of duplicated
     local (Daniel, Eric)
   - use helper variables for width, height and cpp instead of
     repeating the magic numbers over and over again (Eric)
   - use the stride and offset provided by the framework instead of
     hardcoded assumed values (Eric)
   - rewritten excess attribute test vector using only one set of
     attributes with a re-writable slot for one excess attribute
     (Eric)
   - check that EGL stack does not take the ownersip of the buffer
     and revise the explanation for it (Eric)
   - check also for EGL_DMA_BUF_PLANE2_* as excess attributes (Eric)
   - removed irrelevant quotes of the spec (Eric)
   - changed the error expected for non-NULL context from
     'EGL_BAD_CONTEXT' to 'EGL_BAD_PARAMETER' (Eric)

v3:
   - use properly linked egl-extension calls (Eric)
   - make a distinction between invalid and unsupported formats.
     The former is signified by 'EGL_BAD_ATTRIBUTE' while the latter
     generates 'EGL_BAD_MATCH'. There is test only for the former
     as the latter is driver dependent.

v4:
   - add to 'all.tests' (Eric)
   - removed inclusion of standard EGL entrypoints as there is the
     special dispatcher for the test cases to use (Eric)
   - removed irrelevant quote of the spec (Chad)
   - initialised 'pass = true' and used '&& pass'-pattern (Chad, Eric)
