egl: don't allow eglGetConfigs to set num_configs param to a negative value

When a buffer is provided to eglGetConfigs it's supposed to set the value
of the num_config parameter to the total number of configs that have been
copied into this buffer. For some reason the EGL spec doesn't consider it
to be an error to pass this function a buffer while specifying its size to
be less than 0. Given this, one would expect this combination to result in
the num_config parameter being set to 0 but this wasn't the case. This was
due to the buffer size being copied straight into num_configs without being
clamped to 0.

This was causing the following dEQP EGL test to fail:
dEQP-EGL.functional.query_config.get_configs.get_configs_bounds

egl/x11: fix use of EGL_BAD_NATIVE_WINDOW

Commit 4ed23fd590 introduced some calls to _eglError inappropriately
passing it EGL_BAD_NATIVE_WINDOW. This was actually harmless in two of the
cases as _eglError gets called later on with a more appropriate error code
but (just to be safe) switch these to _eglLog calls instead.

The final case is a little trickier as it actually needs to set an error
of which the following are available (according to the EGL spec):
EGL_BAD_MATCH, EGL_BAD_CONFIG, EGL_BAD_NATIVE_(PIXMAP|WINDOW) and
EGL_BAD_ALLOC.

Of these, EGL_BAD_ALLOC seems to be the most appropriate given that
failure can occur either as a result of xcb_get_setup failing due to an
earlier error on the connection (where the most commonly occurring error
code is XCB_CONN_CLOSED_MEM_INSUFFICIENT) or as a result of the
xcb_screen_iterator_t 'rem' field being 0.

In addition to this, commit af2aea40d2 unconditionally set the error to
EGL_BAD_NATIVE_WINDOW when creating a window or pixmap surface with a NULL
native handle. Change this to correctly set the error based on surface
type.

i965: Stop aux data compare preventing program binary re-use

Items in the program cache consist of three things: key, the data
representing the instructions and auxiliary data representing
uniform storage. The data consisting of instructions is stored into
a drm buffer object while the key and the auxiliary data reside in
malloced section. Now the cache uploading is equipped with a check
that iterates over existing items and seeks to find a another item
using identical instruction data than the one being just uploaded.
If such is found there is no need to add another section into the
drm buffer object holding identical copy of the existing one. The
item just being uploaded should instead simply point to the same
offset in the underlying drm buffer object.

Unfortunately the check for the matching instruction data is
coupled with a check for matching auxiliary data also. This
effectively prevents the cache from ever containing two items
that could share a section in the drm buffer object.

The constraint for the instruction data and auxiliary data to
match is, fortunately, unnecessary strong. When items are stored
into the cache they will anyway contain their own copy of the
auxiliary data (even if they matched - which they in real world
never will). The only thing the items would be sharing is the
instruction data and hence we should only check for that to match
and nothing else.

Trivial.
