Add a cogl-version header 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.

Don't use config.h in clutter and cogl In cogl use cogl-config.h and in clutter use clutter-build-config.h. We can't use clutter-config.h in clutter because its already used and installed. https://bugzilla.gnome.org/show_bug.cgi?id=768976

Declare interface types as void and remove cast macros This declares the interface types CoglFramebuffer, CoglBuffer, CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when including the public cogl.h header so that users don't have to use lots of C type casts between instance types and interface types. This also removes all of the COGL_XYZ() type cast macros since they do nothing more than compile time type casting but it's less readable if you haven't seen that coding pattern before. Unlike with gobject based apis that use per-type macros for casting and performing runtime type checking we instead prefer to do our runtime type checking internally within the front-end public apis when objects are passed into Cogl. This greatly reduces the verbosity for users of the api and may help reduce the chance of excessive runtime type checking that can sometimes be a problem. (cherry picked from commit 248a76f5eac7e5ae4fb45208577f9a55360812a7) Since we can't break the 1.x api this version of the patch actually defines compatible NOP macros within deprecated/cogl-type-casts.h
