As we move towards Cogl 2.0 we are aiming to remove the need for a
default global CoglContext and so everything should be explicitly
related to a context somehow. CoglPipelines are top level objects and
so this patch adds a context argument to cogl_pipeline_new().

Most of the conformance tests read a pixel value and assert that it
matches a known value. However they were all doing this with slightly
different methods. This adds a common test_utils_check_pixel function
which they now all use. The function takes an x and y coordinate and a
32-bit value representing the color. It is assumed that writing a
known color is most convenient as an 8 digit hex sequence which this
function allows. There is also a test_utils_check_pixel_rgb function
wrapper which takes the components as separate arguments. This is more
convenient when the expected color is also calculated by the test.

This removes some redundant initializing of the modelview matrix since
we can assume the initial state is already the identity matrix. The
explicit initialization was only really necessary when running as a
clutter test because there the default matrix isn't the identity matrix.
Also some calls to cogl_orth to change the projection matrix have been
moved into the test entry point functions instead of calling this in the
paint function. Again the previous style probably came about because
with clutter we always had to re-assert the projection but now we are in
full control of the projection and can assume it doesn't need
re-asserting once set.

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.
