804082abd3 Expose EGL context/display and GLX context
To help facilitate integration with third party frameworks this exposes
the EGL context and display to applications as well as the GLX context.
(Note that the GLX display is already available via
cogl_xlib_renderer_get_display())

This adds a new top-level <cogl/cogl-glx.h> header that needs to be
included explicitly to access the glx specific api.

Anyone using these apis will be responsible for checking that Cogl
is indeed using EGL or GLX by calling cogl_renderer_get_winsys_id()

This will enable GStreamer, for example, to be able to create a GL
context that shares resources with Cogl's context.

081acdc146 move GLeglImageOES define into cogl-egl-private.h
This splits out the GLeglImageOES define in cogl-egl.h into a private
cogl-egl-private.h header and updates the guards in cogl-egl.h to be
consistent with other top-level headers where we need to be careful
about how __COGL_H_INSIDE__ is defined and undefined, esp when the
gobject introspection scanner is running.

dca992a160 egl: remove NativeWindowType/NativeDisplayType defines
This ensures we use EGLNativeWindowType and EGLNativeDisplayType
everywhere instead. The previous names come from EGL 1.2 but it seems
reasonable to require more recent EGL versions. If someone wanted to add
compatibility for EGL 1.2 later it would be straightforward to define
the new names to the old.

a0441778ad This re-licenses Cogl 1.18 under the MIT license
Since the Cogl 1.18 branch is actively maintained in parallel with the
master branch; this is a counter part to commit 1b83ef938fc16b which
re-licensed the master branch to use the MIT license.

This re-licensing is a follow up to the proposal that was sent to the
Cogl mailing list:
http://lists.freedesktop.org/archives/cogl/2013-December/001465.html

Note: there was a copyright assignment policy in place for Clutter (and
therefore Cogl which was part of Clutter at the time) until the 11th of
June 2010 and so we only checked the details after that point (commit
0bbf50f905)

For each file, authors were identified via this Git command:
$ git blame -p -C -C -C20 -M -M10  0bbf50f905..HEAD

We received blanket approvals for re-licensing all Red Hat and Collabora
contributions which reduced how many people needed to be contacted
individually:
- http://lists.freedesktop.org/archives/cogl/2013-December/001470.html
- http://lists.freedesktop.org/archives/cogl/2014-January/001536.html

Individual approval requests were sent to all the other identified authors
who all confirmed the re-license on the Cogl mailinglist:
http://lists.freedesktop.org/archives/cogl/2014-January

As well as updating the copyright header in all sources files, the
COPYING file has been updated to reflect the license change and also
document the other licenses used in Cogl such as the SGI Free Software
License B, version 2.0 and the 3-clause BSD license.

This patch was not simply cherry-picked from master; but the same
methodology was used to check the source files.

4f6fe6f0e2 Fixes for --disable-glib
This fixes some problems which were stopping --disable-glib from
working properly:

• A lot of the public headers were including glib.h. This shouldn't be
  necessary because the API doesn't expose any glib types. Otherwise
  any apps would require glib in order to get the header.

• The public headers were using G_BEGIN_DECLS. There is now a
  replacement macro called COGL_BEGIN_DECLS which is defined in
  cogl-types.h.

• A similar fix has been done for G_GNUC_NULL_TERMINATED and
  G_GNUC_DEPRECATED.

• The CFLAGS were not including $(builddir)/deps/glib which was
  preventing it finding the generated glibconfig.h when building out
  of tree.
