Remove the "If only executable code is distributed..." paragraph from
the license text. Everything now uses a normal MIT license.
The only code from Khronos that's included in libglvnd is the EGL/GL
header and XML files, which do not contain that paragraph.
Fixes https://gitlab.freedesktop.org/glvnd/libglvnd/-/issues/221
Fix the message types in the _eglReportError and _eglReportCritical macros.
In eglDebugMessageControlKHR, check if the attribute list is valid even if the
callback is NULL.
In eglDebugMessageControlKHR, set the callback pointer whether or not the
attribute list is NULL.
In eglLabelObjectKHR, if the vendor library returns an error for an object type
other than EGL_OBJECT_THREAD_KHR, then return that error to the caller.
Fix the error handling and return value in eglBindAPI if the API isn't one of
GL or GLES.
Add a missing error callback in eglMakeCurrent.
Implemented the EGL_KHR_debug extension in libEGL.
Updated the error reporting throughout libEGL to call the debug callback.
This requires that all vendor libraries also support EGL_KHR_debug. The reason
is that the debug callback has to be called every time an EGL error is
generated, and vendor libraries are still responsible for keeping track of EGL
errors on their own.
libEGL should be able to cope with a vendor library that doens't support
EGL_KHR_debug, but if that vendor library is used, then the extension won't
work correctly.
