cogl-program: Move the code for CoglBoxedValue to its own file The code for manipulating CoglBoxedValues is now separated from cogl-program.c into its own file. That way when we add support for setting uniform values on a CoglPipeline the code for storing the values can be shared. Reviewed-by: Robert Bragg <robert@linux.intel.com>

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.
