Having spent the last dev cycle looking at how we could specialize the
compositors for various backends, we once again look for the
commonalities in order to reduce the duplication. In part this is
motivated by the idea that spans is a good interface for both the
existent GL backend and pixman, and so they deserve a dedicated
compositor. xcb/xlib target an identical rendering system and so they
should be using the same compositor, and it should be possible to run
that same compositor locally against pixman to generate reference tests.

P.S. This brings massive upheaval (read breakage) I've tried delaying in
order to fix as many things as possible but now this one patch does far,
far, far too much. Apologies in advance for breaking your favourite
backend, but trust me in that the end result will be much better. :)
_cairo_atomic_int_set() was only used in the definition of
CAIRO_REFERENCE_SET_VALUE, which was never used.

I updated the Free Software Foundation address using the following script.
for i in $(git grep Temple | cut -d: -f1 )
do
sed -e 's/59 Temple Place[, -]* Suite 330, Boston, MA *02111-1307[, ]* USA/51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA/' -i "$i"
done

The macros CAIRO_BEGIN_DECLS and CAIRO_END_DECLS are declared in two
places: config.h and cairo.h. On Win32 build there is no config.h. So,
we can't rely on pulling CAIRO_BEGIN_DECLS from there. Hence, we now:
* Not add those declarations to config.h anymore,
* Test that every cairo private header includes some other cairo
header before any other includes.
These two are fairly enough to ensure that cairo.h is seen from all
private headers. There's still the case of headers not including
any header file at all. I'll fix that later.
Quick summary of changes:
- Move list of cairo source files out of src/Makefile.am and into
src/Sources.mk,
- Generate files src/Config.mk and src/Config.mk.win32 that choose
the right set of source files and headers based on configured
backends and features. This drastically simplifies building
using other build systems. The src/Makefile.win32 file needs
to be updated to reflect these changes.
- Add README files to various directories,
- Add toplevel HACKING file.
Introduce an opaque cairo_reference_count_t and define operations on it
in terms of atomic ops. Update all users of reference counters to use
the new opaque type.
