This adds much more comprehensive support for gobject-introspection
based bindings by registering all objects as fundamental types that
inherit from CoglObject, and all structs as boxed types.

Since the Cogl 1.18 branch is actively maintained in parallel with the
master branch; this is a counter part to commit 1b83ef938fc16b which
re-licensed the master branch to use the MIT license.
This re-licensing is a follow up to the proposal that was sent to the
Cogl mailing list:
http://lists.freedesktop.org/archives/cogl/2013-December/001465.html
Note: there was a copyright assignment policy in place for Clutter (and
therefore Cogl which was part of Clutter at the time) until the 11th of
June 2010 and so we only checked the details after that point (commit
0bbf50f905)
For each file, authors were identified via this Git command:
$ git blame -p -C -C -C20 -M -M10 0bbf50f905..HEAD
We received blanket approvals for re-licensing all Red Hat and Collabora
contributions which reduced how many people needed to be contacted
individually:
- http://lists.freedesktop.org/archives/cogl/2013-December/001470.html
- http://lists.freedesktop.org/archives/cogl/2014-January/001536.html
Individual approval requests were sent to all the other identified authors
who all confirmed the re-license on the Cogl mailinglist:
http://lists.freedesktop.org/archives/cogl/2014-January
As well as updating the copyright header in all sources files, the
COPYING file has been updated to reflect the license change and also
document the other licenses used in Cogl such as the SGI Free Software
License B, version 2.0 and the 3-clause BSD license.
This patch was not simply cherry-picked from master; but the same
methodology was used to check the source files.
The Cogl 1.x API exports cogl_set_path() and cogl_get_path(), which
means that the regular expression needs to catch those two symbols
as well.

Since we now have more time to ensure that Clutter is updated to check
for the now separate cogl-path package as part of its build
configuration we are now making the package split, in line with Cogl
master.

This reverts commit bc41489336.
The reason this was causing problems for Clutter is that it defines
COGL_ENABLE_EXPERIMENTAL_2_0_API which is meant to cause the Cogl
headers not to declare the deprecated API. The reverted patch moved
some additional clipping API to a deprecated header which was
previously being used by Clutter. Clutter was still successfully
compiling but with some warnings for the missing function
declarations. However when the binary is run the clipping would get
completely messed up because it would assume all of the arguments to
the functions are integers instead of floats and the wrong values
would be passed.
Clutter now has commit to make it use the 2.0 API instead of the
deprecated functions so the revert is no longer necessary.

This reverts commit ae9cd7ca01.
Pushing this for now so we can get gnome-shell working again without
memory corruption. Let's push a proper fix later for everybody.
There used to be a function called cogl_clip_stack_save in the public
API which was used when temporarily switching to an offscreen buffer
to save the clip state. This is no longer necessary because each
framebuffer has its own clip stack anyway so the function was removed
in master. However the code to maintain the stack of stacks was
retained. This patch removes it in an effort to simplify the code.
On the 1.18 branch this function is deprecated and the documentation
says that it does nothing. However that is incorrect because it does
actually the push clip stack. I think it would be safe to backport
this patch to the 1.18 branch and actually make it do nothing like it
is documented to do.

This patch has some extra changes while backporting to the 1.18
branch. Here the cogl-clip-state file still contained some deprecated
functions. Instead of deleting the file completely it has been moved
to the deprecated folder. The declarations for this functions have
been moved from cogl1-context.h to a new deprecated/cogl-clip-state.h
header.

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.

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
This adds a centralized autotools Makefile to be used in the completion
of the project files for Cogl-Path for now, which can be used also in
Cogl, Cogl-Pango and possibly Cogl-Gst so that we could have less clutter
in the autotools files.
This patch set will also allow the Cogl-Path project files to be filled in
during 'make dist' and make them distributed during a tarball release.

The data->fill_primitive member is meant to be generated on demand in
an accessor function. However when using it for clipping the code was
trying to directly use it without calling the accessor so it would
crash if nothing else caused the primitive to be generated. This was
making the texture-fbo test in Clutter crash.

This splits out the cogl_path_ api into a separate cogl-path sub-library
like cogl-pango and cogl-gst. This enables developers to build Cogl with
this sub-library disabled if they don't need it which can be useful when
its important to keep the size of an application and its dependencies
down to a minimum. The functions cogl_framebuffer_{fill,stroke}_path
have been renamed to cogl_path_{fill,stroke}.
There were a few places in core cogl and cogl-gst that referenced the
CoglPath api and these have been decoupled by using the CoglPrimitive
api instead. In the case of cogl_framebuffer_push_path_clip() the core
clip stack no longer accepts path clips directly but it's now possible
to get a CoglPrimitive for the fill of a path and so the implementation
of cogl_framebuffer_push_path_clip() now lives in cogl-path and works as
a shim that first gets a CoglPrimitive and uses
cogl_framebuffer_push_primitive_clip instead.
We may want to consider renaming cogl_framebuffer_push_path_clip to
put it in the cogl_path_ namespace.

So as to avoid breaking the 1.x API or even the ABI since we are quite
late in the 1.16 development cycle the patch was modified to build
cogl-path as a noinst_LTLIBRARY before building cogl and link the code
directly into libcogl.so as it was previously. This way we can wait
until the start of the 1.18 cycle before splitting the code into a
separate libcogl-path.so.
This also adds shims for cogl_framebuffer_fill/stroke_path() to avoid
breaking the 1.x API/ABI.
