43efab46bc Intial Re-layout of the Cogl source code and introduction of a Cogl Winsys
As part of an incremental process to have Cogl be a standalone project we
want to re-consider how we organise the Cogl source code.

Currently this is the structure I'm aiming for:
cogl/
    cogl/
	<put common source here>
	winsys/
	   cogl-glx.c
	   cogl-wgl.c
	driver/
	    gl/
	    gles/
	os/ ?
    utils/
	cogl-fixed
	cogl-matrix-stack?
        cogl-journal?
        cogl-primitives?
    pango/

The new winsys component is a starting point for migrating window system
code (i.e.  x11,glx,wgl,osx,egl etc) from Clutter to Cogl.

The utils/ and pango/ directories aren't added by this commit, but they are
noted because I plan to add them soon.

Overview of the planned structure:

* The winsys/ API is the API that binds OpenGL to a specific window system,
  be that X11 or win32 etc.  Example are glx, wgl and egl. Much of the logic
  under clutter/{glx,osx,win32 etc} should migrate here.

* Note there is also the idea of a winsys-base that may represent a window
  system for which there are multiple winsys APIs.  An example of this is
  x11, since glx and egl may both be used with x11.  (currently only Clutter
  has the idea of a winsys-base)

* The driver/ represents a specific varient of OpenGL. Currently we have "gl"
  representing OpenGL 1.4-2.1 (mostly fixed function) and "gles" representing
  GLES 1.1 (fixed funciton) and 2.0 (fully shader based)

* Everything under cogl/ should fundamentally be supporting access to the
  GPU.  Essentially Cogl's most basic requirement is to provide a nice GPU
  Graphics API and drawing a line between this and the utility functionality
  we add to support Clutter should help keep this lean and maintainable.

* Code under utils/ as suggested builds on cogl/ adding more convenient
  APIs or mechanism to optimize special cases. Broadly speaking you can
  compare cogl/ to OpenGL and utils/ to GLU.

* clutter/pango will be moved to clutter/cogl/pango

How some of the internal configure.ac/pkg-config terminology has changed:
backendextra -> CLUTTER_WINSYS_BASE # e.g. "x11"
backendextralib -> CLUTTER_WINSYS_BASE_LIB # e.g. "x11/libclutter-x11.la"
clutterbackend -> {CLUTTER,COGL}_WINSYS # e.g. "glx"
CLUTTER_FLAVOUR -> {CLUTTER,COGL}_WINSYS
clutterbackendlib -> CLUTTER_WINSYS_LIB
CLUTTER_COGL -> COGL_DRIVER # e.g. "gl"

Note: The CLUTTER_FLAVOUR and CLUTTER_COGL defines are kept for apps

As the first thing to take advantage of the new winsys component in Cogl;
cogl_get_proc_address() has been moved from cogl/{gl,gles}/cogl.c into
cogl/common/cogl.c and this common implementation first trys
_cogl_winsys_get_proc_address() but if that fails then it falls back to
gmodule.

ecfa0c4f92 [build] Split out the custom silent rules
The silent rules we use for custom targets should be moved into a
separate Makefile.am that gets included from all the others.

3425331cc1 [tests/tools] Don't install libdisable-npots.so
The libdisable-npots library is just used as a helper as part of
make test so it should not be installed.

If noinst_* is used then automake will generate a static library but
this won't work with LD_PRELOAD so we then need an extra custom rule
to link that into a shared library. The custom rule uses the $(LINK)
Makefile var which gets put in the Makefile because of the static
library. We pass libtool a stub -rpath option which causes it to
generate a shared library.

e5543a658f Make libdisable-npots a bit more portable
Instead of including GL/gl.h directly it now includes cogl/cogl.h
instead which should include the right GL header.

Instead of using dlopen to specifically open libGL it now tries to use
dlsym with RTLD_NEXT. This requires defining _GNU_SOURCE on GNU
systems. If RTLD_NEXT is not available it will try passing NULL which
is unlikely to work but it will at least catch the case where it
returns the wrapper version of glGetString to prevent infinite
recursion.

This should hopefully make it work on OS X where the name of the
header and library are different (although this is currently
untested).

596d4628e6 Add a wrapper library to help testing without NPOTs.
* tests/tools/Makefile.am: Optionally build the
	libdisable-npots.la library depending on whether libdl was
	detected in the configure script. A helper script is also
	generated to setup the LD_PRELOAD.

	* tests/conform/Makefile.am: There are now two versions of the
	test-report and full-report rules. test-report-normal is the same
	as before and test-report-disable-npots runs the tests with the
	disable-npots wrapper script. The full-report rule runs both of
	them and displays two separate HTML files. The test-report rule
	just runs the normal version as before.

	* configure.ac: Add a test for libdl

	* tests/tools/disable-npots.sh.in: New file. Template for the
	helper script

	* tests/tools/disable-npots.c: New file

603f936745 Bug 1162 - Re-works the tests/ to use the glib-2.16 unit testing
framework

	* configure.ac:
	* tests/*:
	The tests have been reorganised into different categories: conformance,
	interactive and micro benchmarks.
	- conformance tests can be run as part of automated tests
	- interactive tests are basically all the existing tests
	- micro benchmarks focus on a single performance metric

	I converted the timeline tests to conformance tests and also added some
	tests from Neil Roberts and Ebassi.

	Note: currently only the conformance tests use the glib test APIs,
	though the micro benchmarks should too.

	The other change is to make the unit tests link into monolithic binaries
	which makes the build time for unit tests considerably faster. To deal
	with the extra complexity this adds to debugging individual tests I
	have added some sugar to the makefiles so all the tests can be run
	directly via a symlink and when an individual test is run this way,
	then a note is printed to the terminal explaining exactly how that test
	may be debugged using GDB.

	There is a convenience make rule: 'make test-report', that will run all
	the conformance tests and hopefully even open the results in your web
	browser. It skips some of the slower timeline tests, but you can run
	those using 'make full-report'
