Some bits were already there for texture views but some were missing.
In particular for cube map views things needed to change a bit.
For simplicity I ended up removing the separate face addr bit (just use
the z bit) - cube arrays didn't use it already, so just follow the same
logic there. (In theory using separate bits could allow for better hash
function but I don't think anyone ever did some measurements of that so
probably not worth the trouble, if we'd reintroduce it we'd certainly
wanted to use the same logic for cube arrays and cube maps.)
Also extend the seamless cube sampling to cube arrays - as there were no
piglit failures before this is apparently untested, but things now generally
work quite the same for cube textures and cube array textures so there
hopefully shouldn't be any trouble...

49 new piglits, 47 pass, 2 fail (both due to fake multisampling).

v2: incorporate Brian's feedback, add sampler view validation,
function rename, formatting fixes.

All the functionality was pretty much there, just not tested.
Trivially fix up the missing pieces (take target info from view not
resource), and add some missing bits for cubes.
Also add some minimal debug validation to detect uninitialized target values
in the view...

49 new piglits, 47 pass, 2 fail (both related to fake multisampling,
not texture_view itself). No other piglit changes.

v2: move sampler view validation to sampler view creation, update docs.

This enables EGL_KHR_fence_sync and EGL_KHR_wait_sync.

Below is the difference in piglit results, before and after this patch.
No regressions and several tests improve from 'skip' to 'pass'. Out of
EGL_KHR_fence_sync tests, two of the multithreaded tests skip; all other
tests pass.
