Only keep track of a single current context, instead of separate
contexts for GL and GLES.
In EGL 1.4 (and 1.5), EGL_OPENGL_API and EGL_OPENGL_ES_API are supposed
to be interchangeable for all purposes except for eglCreateContext.
The _EGLThreadInfo::CurrentContexts array is now a single pointer to the
current context, which may be a GL or GLES context. In addition, it now
keeps track of the current API as an enum instead of an index.
eglMakeCurrent will now replace the current context, regardless of which
client API is used for for the current and new contexts. It no longer
checks for a conflicting context. In addition, calling eglMakeCurrent
with EGL_NO_CONTEXT will now release the current context regardless of
the current API.

This patch enables an EGL extension, EGL_KHR_reusable_sync.
This new extension basically provides a way for multiple APIs or
threads to be excuted synchronously via a "reusable sync"
primitive shared by those threads/API calls.
This was implemented based on the specification at
https://www.khronos.org/registry/egl/extensions/KHR/EGL_KHR_reusable_sync.txt
v2
- use thread functions defined in C11/threads.h instead of
using direct pthread calls
- make the timeout set with reference to CLOCK_MONOTONIC
- cleaned up the way expiration time is calculated
- (bug fix) in dri2_client_wait_sync, case EGL_SYNC_CL_EVENT_KHR
has been added.
- (bug fix) in dri2_destroy_sync, return from cond_broadcast
call is now stored in 'err' intead of 'ret' to prevent 'ret'
from being reset to 'EGL_FALSE' even in successful case
- corrected minor syntax problems
v3
- dri2_egl_unref_sync now became 'void' type. No more error check
is needed for this function call as a result.
- (bug fix) resolved issue with duplicated unlocking of display in
eglClientWaitSync when type of sync is "EGL_KHR_REUSABLE_SYNC"

Patch provides a default for a set pbuffer surface size when
EGL_LARGEST_PBUFFER is used by the client. MIN2 macro is moved
to egldefines so that it can be shared.
Fixes following Piglit test:
egl-create-largest-pbuffer-surface
From EGL 1.5 spec:
"Use EGL_LARGEST_PBUFFER to get the largest available pbuffer
when the allocation of the pbuffer would otherwise fail."
Currently there exists no API to query largest available pixmap size
using xlib or xcb so right now this seems most straightforward way to
ensure that we fulfill above API and also we don't attempt to allocate
'too big' pixmap which might succeed on server side but not work in
practice when driver starts to use it as a texture.

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:

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.
