Avoid calling libtool to link every single test case, by building just one
binary from all the sources.
This binary is then given the task of choosing tests to run (based on user
selection and individual test requirement), forking each test into its own
process and accumulating the results.
src/cairo-array.c src/cairoint.h src/cairo-surface.c: Refactor user data code from cairo-surface.c into cairo_user_data_array_t.
Switch these types to be like cairo_surface_t where the generic code frees the wrapper object.
src/cairo-atsui-font.c src/cairo-ft-font.c src/cairo-win32-font.c: Fix up for the above changes.
Implement a complicated mutual-referencing scheme to make sure that a face from cairo_ft_font_face_create_for_ft_face() is freed only when the FT_Face is no longer needed.
Update the docs to describe how to figure out when the FT_Face can be freed.
Fix refcount leaks when creating fonts.
Remove excess call to _cairo_unscaled_font_reference().
Remove stray initialization of font matrix to the identity.
test/user-data.c: Fix a bug when setting/unsetting a key with a free key slot before it, add that to the test case.
Don't append an element when user_data is NULL.
Add const qualifier to cairo_user_data_key_t arguments.
