glx: Fix __glXWireToEvent for BufferSwapComplete

In the DRI2 path this event is magically synthesized from the
corresponding DRI2 event, but with Present, the server sends us the

egl: improve attribute checking for eglCreateContext

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.

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

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.
