This commit pushes --disable-glib to the extreme of embedding the par of
glib cogl depends on in tree to be able to generate a DSO that does not
depend on an external glib.
To do so, it:
- keeps a lot of glib's configure.ac in as-glibconfig.m4
- pulls the code cogl depends on and the necessary dependencies

The test creates a pipeline with two layers which add two different
color constants together and then tries various combinations of
removing the layers and checks that it gets the right color.
Currently this is failing if a pipeline is copied and then a layer is
removed from the copy.

This adds a version header which contains macros to define which
version of Cogl the application is being compiled against. This helps
applications that want to support multiple incompatible versions of
Cogl at compile time.
The macros are called COGL_VERSION_{MAJOR,MINOR,MICRO}. This does not
match Clutter which names them CLUTTER_{MAJOR,MINOR,MICRO}_VERSION but
I think the former is nicer and it at least matches Cairo and Pango.
The values of the macro are defined to COGL_VERSION_*_INTERNAL which
is generated by the configure script into cogl-defines.h.
There is also a macro for the entire version as a string called
COGL_VERSION_STRING.
The internal utility macros for encoding a 3 part version number into
a single integer have been moved into the new header so they can be
used publicly as a convenient way to check if the version is within a
particular range. There is also a COGL_VERSION_CHECK macro for the
very common case that a feature will be used since a particular
version of Cogl. There is a macro called COGL_VERSION which contains
the pre-encoded version of Cogl being compiled against for
convenience.
Unlike in Clutter this patch does not add any runtime version
identification mechanism.
A test case is also added which just contains static asserts to sanity
check the macros.

This splits the GL header inclusion from cogl-defines.h into a
separate headear called cogl-gl-header.h which we will only include
internally. That way we don't leak GL declarations out of our public
headers. The texture functions that were using GLenum and GLuint in
the public header have now changed to just use unsigned int. Note
however that if an EGL winsys is enabled then it will still publicly
include an EGL header. This is a bit more awkward to fix because we
have public API which returns an EGLDisplay and we can't determine
what type that is.
There is also a conformance test which just verifies that no GL header
has been included while compiling. The test isn't added to
test-conform-main because it doesn't actually test anything at
runtime.

This adds a conformance test which renders a texture point using a 2x2
texture with a different color for each texel. It then verifies that
each texel is mapped to the correct position on the point. The test is
currently failing.
The test requires the point sprite feature flag so this patch also
adds a TEST_REQUIREMENT_* flag for that.

This adds a test similar to the test-read-texture-formats test but
that updates data on a 1x1 pixel RGBA texture instead. On GLES2 this

GL only supports reading back RGBA data.

The test-read-alpha-texture test has been replaced with a test that
tries reading an RGBA texture in all current pixel formats. On GLES2
this should end up testing all of the convesion code because in that
case GL only supports reading back RGBA data. The test now works on
GLES2 since the conversion code for all of the formats has been added
so this also removes the GL requirement.

This just creates a 1x1 RGBA texture and then reads it back in

This patch reworks our conformance testing framework because it seems
that glib's gtesting framework isn't really well suited to our use case.
For example we weren't able to test windows builds given the way we
were using it and also for each test we'd like to repeat the test
with several different environments so we can test important driver and
feature combinations.
This patch instead switches away to a simplified but custom approach for
running our unit tests. We hope that having a more bespoke setup will
enable us to easily extend it to focus on the details important to us.
Notable changes with this new approach are:
We can now run 'make test' for our mingw windows builds.
We've got rid of all the test-*report* make rules and we're just left
with 'make test'
'make test' now runs each test several times with different driver and
feature combinations checking the result for each run. 'make test' will
then output a concise table of all of the results.
The combinations tested are:
- OpenGL Fixed Function
- OpenGL ARBfp
- OpenGL GLSL
- OpenGL No NPOT texture support
- OpenGLES 2.0
- OpenGLES 2.0 No NPOT texture support

There are currently quite a few places in Cogl where we muddle the
layer index and the texture unit number. The theory is that these two
numbers shouldn't be related and it should be possible to pick large
layer numbers with gaps.
This patch adds a test case to check that we can reference a large
layer number from a texture combine string by creating a pipeline with
only three layers but that have very large layer indices. This doesn't
currently work because Cogl interprets the numbers in the combine
strings to be the unit indices and not the layer indices. The
documentation however calls these numbers layer numbers so presumably
it is not meant to work that way.
There are probably many other bugs related to this that the test case
doesn't pick up so it would be good to add some more tests here, for
example to test that you can bind an attribute to the texture
coordinates for a large layer index.

This adds a test which tries manipulating some bits on a CoglBitmask
and verifies that it gets the expected result. This test is fairly
unusual in that it is directly testing some internal Cogl code that
isn't exposed through the public API. To make this work it directly
includes the source for CoglBitmask.
CoglBitmask does some somewhat dodgy things with converting longs to
pointers and back so it makes sense to have a test case to verify that
this is working on all platforms.

This makes a start on porting the Cogl conformance tests that currently
still live in the Clutter repository to be standalone Cogl tests that no
longer require a ClutterStage.
The main thing is that this commit brings in is the basic testing
infrastructure we need, so now we can port more and more tests
incrementally.
Since the test suite wants a way to synchronize X requests/replies and
we can't simply call XSynchronize in the test-utils code before we know
if we are really running on X this adds a check for an environment
variable named "COGL_X11_SYNC" in cogl-xlib-renderer.c and if it's set
it forces XSynchronize (dpy, TRUE) to be called.
By default the conformance tests are run off screen. This makes the
tests run much faster and they also don't interfere with other work you
may want to do by constantly stealing focus. CoglOnscreen framebuffers
obviously don't get tested this way so it's important that the tests
also get run on screen every once in a while, especially if changes are
being made to CoglFramebuffer related code. On screen testing can be
enabled by setting COGL_TEST_ONSCREEN=1 in your environment.
