cogl: Include DRM 4CC conversions into CoglPixelFormat

This is at the moment still part of both MetaRendererNative and
MetaDmaBuf, which means duplicated effort in code sections only barely
related to color formats. By doing this, we can keep more of the pixel
format code together, which is more future-proof as we want to add
support for new pixel formats (like YUV-based ones).

+/**
+ * SECTION:cogl-error
+ * @short_description: A way for Cogl to throw exceptions
+ *
+ * As a general rule Cogl shields non-recoverable errors from
+ * developers, such as most heap allocation failures (unless for
+ * exceptionally large resources which we might reasonably expect to
+ * fail) and this reduces the burden on developers.
+ *
+ * There are some Cogl apis though that can fail for exceptional
+ * reasons that can also potentially be recovered from at runtime
+ * and for these apis we use a standard convention for reporting
+ * runtime recoverable errors.
+ *
+ * As an example if we look at the cogl_context_new() api which
+ * takes an error argument:
+ * |[
+ *   CoglContext *
+ *   cogl_context_new (CoglDisplay *display, CoglError **error);
+ * ]|
+ *
+ * A caller interested in catching any runtime error when creating a
+ * new #CoglContext would pass the address of a #CoglError pointer
+ * that has first been initialized to %NULL as follows:
+ *
+ * |[
+ *   CoglError *error = NULL;
+ *   CoglContext *context;
+ *
+ *   context = cogl_context_new (NULL, &error);
+ * ]|
+ *
+ * The return status should usually be enough to determine if there
+ * was an error set (in this example we can check if context == %NULL)
+ * but if it's not possible to tell from the function's return status
+ * you can instead look directly at the error pointer which you
+ * initialized to %NULL. In this example we now check the error,
+ * report any error to the user, free the error and then simply
+ * abort without attempting to recover.
+ *
+ * |[
+ *   if (context == NULL)
+ *     {
+ *       fprintf (stderr, "Failed to create a Cogl context: %s\n",
+ *                error->message);
+ *       cogl_error_free (error);
+ *       abort ();
+ *     }
+ * ]|
+ *
+ * All Cogl APIs that accept an error argument can also be passed a
+ * %NULL pointer. In this case if an exceptional error condition is hit
+ * then Cogl will simply log the error message and abort the
+ * application. This can be compared to language execeptions where the
+ * developer has not attempted to catch the exception. This means the
+ * above example is essentially redundant because it's what Cogl would
+ * have done automatically and so, similarly, if your application has
+ * no way to recover from a particular error you might just as well
+ * pass a %NULL #CoglError pointer to save a bit of typing.
+ *
+ * <note>If you are used to using the GLib API you will probably
+ * recognize that #CoglError is just like a #GError. In fact if Cogl
+ * has been built with --enable-glib then it is safe to cast a
+ * #CoglError to a #GError.</note>
+ *
+ * <note>An important detail to be aware of if you are used to using
+ * GLib's GError API is that Cogl deviates from the GLib GError
+ * conventions in one noteable way which is that a %NULL error pointer
+ * does not mean you want to ignore the details of an error, it means
+ * you are not trying to catch any exceptional errors the function might
+ * throw which will result in the program aborting with a log message
+ * if an error is thrown.</note>
