Add a CoglFrameInfo object that tracks timing information for frames
that are drawn. We track a frame counter and frame timing information
for each CoglOnscreen. Internally a CoglFrameInfo is automatically
created for each frame, delimited by cogl_onscreen_swap_buffers() or
cogl_onscreen_swap_region() calls.
CoglFrameInfos are delivered to applications via frame event callbacks
that can be registered with a new cogl_onscreen_add_frame_callback()
api. Two initial event types (dispatched on all platforms) have been
defined; a _SYNC event used for throttling the frame rate of
applications and a _COMPLETE event used so signify the end of a frame.
Note: This new _add_frame_callback() api makes the
cogl_onscreen_add_swap_complete_callback() api redundant and so it
should be considered deprecated. Since the _add_swap_complete_callback()
api is still experimental api, we will be looking to quickly migrate
users to the new api so we can remove the old api.

This fixes some problems which were stopping --disable-glib from
working properly:
• A lot of the public headers were including glib.h. This shouldn't be
necessary because the API doesn't expose any glib types. Otherwise
any apps would require glib in order to get the header.
• The public headers were using G_BEGIN_DECLS. There is now a
replacement macro called COGL_BEGIN_DECLS which is defined in
cogl-types.h.
• A similar fix has been done for G_GNUC_NULL_TERMINATED and
G_GNUC_DEPRECATED.
• The CFLAGS were not including $(builddir)/deps/glib which was
preventing it finding the generated glibconfig.h when building out
of tree.

This adds api to be able to request that the window system allows a
given onscreen framebuffer to be resizable, and api to add and remove
resize handlers to be called whenever the framebuffer does actually
change size.
The new functions are:
cogl_onscreen_{get,set}_resizable()
cogl_onscreen_{add,remove}_resize_handler()
The examples cogl-hello and cogl-x11-foreign have been updated to use
the new api. To smoke test how Cogl updates the viewport automatically
in response to window resizes the cogl-hello test doesn't explicitly
respond to resize events by setting the viewport and cogl-x11-foreign
responds by setting a viewport that is offset by a quarter of the
window's width/height and half the width and height of the window.

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.

This option to GCC makes it give a warning whenever a global function
is defined without a declaration. This should catch cases were we've
defined a function but forgot to put it in a header. In that case it
is either only used within one file so we should make it static or we
should declare it in a header.
The following changes where made to fix problems:
• Some functions were made static
• cogl-path.h (the one containing the 1.0 API) was split into two
files, one defining the functions and one defining the enums so that
cogl-path.c can include the enum and function declarations from the
2.0 API as well as the function declarations from the 1.0 API.
• cogl2-clip-state has been removed. This only had one experimental
function called cogl_clip_push_from_path but as this is unstable we
might as well remove it favour of the equivalent cogl_framebuffer_*
API.
• The GLX, SDL and WGL winsys's now have a private header to define
their get_vtable function instead of directly declaring in the C
file where it is called.
• All places that were calling COGL_OBJECT_DEFINE need to have the
cogl_is_whatever function declared so these have been added either
as a public function or in a private header.
• Some files that were not including the header containing their
function declarations have been fixed to do so.
• Any unused error quark functions have been removed. If we later want
them we should add them back one by one and add a declaration for
them in a header.
• _cogl_is_framebuffer has been renamed to cogl_is_framebuffer and
made a public function with a declaration in cogl-framebuffer.h
• Similarly for CoglOnscreen.
• cogl_vdraw_indexed_attributes is called
cogl_framebuffer_vdraw_indexed_attributes in the header. The
definition has been changed to match the header.
• cogl_index_buffer_allocate has been removed. This had no declaration
and I'm not sure what it's supposed to do.
• CoglJournal has been changed to use the internal CoglObject macro so
that it won't define an exported cogl_is_journal symbol.
• The _cogl_blah_pointer_from_handle functions have been removed.
CoglHandle isn't used much anymore anyway and in the few places
where it is used I think it's safe to just use the implicit cast
from void* to the right type.
• The test-utils.h header for the conformance tests explicitly
disables the -Wmissing-declaration option using a pragma because all
of the tests declare their main function without a header. Any
mistakes relating to missing declarations aren't really important
for the tests.
• cogl_quaternion_init_from_quaternion and init_from_matrix have been
given declarations in cogl-quaternion.h

This moves all the cogl_framebuffer_ apis relating to swap buffer

Resizing a wayland client framebuffer should not affect the viewport
of additional primitives drawn to that framebuffer before the next swap
buffers request nor should querying the framebuffer's width and height
be affected until the next swap buffers request completes.
This patch changes cogl_wayland_onscreen_resize() so it only saves the
new geometry as "pending" state internal to the given CoglOnscreen. Only
when cogl_framebuffer_swap_buffers() is next called will the pending
size be flushed to the wayland egl api.
We've avoiding using the redundant glib typedefs such as guint, gint
gpointer etc and prefer to use the equivalent C types so this patch
removes a few uses of gint that slipped past review.
We are in the process of removing all _EXP suffix mangling for
experimental APIs (Ref: c6528c4b6c) and adding missing gtk-doc
comments so that we can instead rely on the "Stability: unstable"
markers in the gtk-doc comments. This patch tackles the onscreen
framebuffer api symbols.
This function will call into the Wayland EGL platform API and resize the
surface that the window is using and update the internal dimensions for
framebuffer and viewport to reflect the change.

Notably some of the functions pulled out are currently namespaced as
cogl_framebuffer but we know we are planning on renaming them to be in
