The EGL 1.4 spec states for eglCreateContext:
"attribute EGL_CONTEXT_CLIENT_VERSION is only valid when the current
rendering API is EGL_OPENGL_ES_API"
Additionally, if the EGL_KHR_create_context EGL extension is supported
(this is mandatory in EGL 1.5) then the EGL_CONTEXT_MAJOR_VERSION_KHR,
which is an alias for EGL_CONTEXT_CLIENT_VERSION, and
EGL_CONTEXT_MINOR_VERSION_KHR attributes are also accepted by
eglCreateContext with the extension spec stating:
"The values for attributes EGL_CONTEXT_MAJOR_VERSION_KHR and
EGL_CONTEXT_MINOR_VERSION_KHR specify the requested client API
version. They are only meaningful for OpenGL and OpenGL ES
contexts, and specifying them for other types of contexts will
generate an error."
Add the necessary checks against the extension and rendering APIs when
validating these attributes as part of eglCreateContext.

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:

When calling either eglCreateWindowSurface or eglCreatePixmapSurface it
was possible for an application to be aborted as a result of it failing
to create a DRI2 drawable on the server. This could happen due to an
application passing in an invalid native drawable handle, for example.

Both eglCreatePixmapSurface and eglCreateWindowSurface were incorrectly
setting the EGL error to be EGL_BAD_ALLOC when an invalid native drawable

eglCreatePixmapSurface:
"If pixmap is not a valid native pixmap handle, then an EGL_BAD_-
NATIVE_PIXMAP error should be generated."
(eglCreateWindowSurface has similar text)

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.

Calling eglQuerySurface on a window or pixmap with the EGL_LARGEST_PBUFFER
attribute resulted in the contents of the 'value' parameter being modified.
This is the wrong behaviour according to the EGL spec, which states:
"Querying EGL_LARGEST_PBUFFER for a pbuffer surface returns the
same attribute value specified when the surface was created with
eglCreatePbufferSurface. For a window or pixmap surface, the
contents of value are not modified."
Avoid this from happening by checking that the surface type is EGL_PBUFFER_BIT
before modifying the contents of the parameter.
